Display BGP routes originated in the local AS
The easiest way to display BGP routes originating in the local autonomous system is to use the regular expression ^$ (empty AS-path) in the show ip bgp regexp command, for example:
PE-A#show ip bgp regexp ^$
BGP table version is 10, local
router ID is 10.0.1.1
Status codes: s suppressed, d damped, h history,
* valid, > best, i - internal,
r RIB-failure, S
Stale
Origin codes: i - IGP, e - EGP, ? - incomplete
Network
Next Hop Metric LocPrf Weight Path
*> 10.0.1.1/32
0.0.0.0 0 32768 i
r>i10.0.1.2/32
10.0.1.2 0 100 0 i
If you want to apply a show filter to the printout of this command, you have to use the quote-regexp variant; otherwise the rest of the line is interpreted as regular expression. To skip the header explaining the BGP status code (we know them by heart by now, don’t we?), use …
PE-A#show ip bgp
quote-regexp "^$" begin Network
Network Next Hop Metric LocPrf Weight Path
*>
10.0.1.1/32 0.0.0.0 0 32768
i
r>i10.0.1.2/32 10.0.1.2 0 100 0
i
… and end with the eye candy – define this command as an alias: alias exec localbgp show ip bgp quote-regexp "^$" begin Network.
Use the explicit "address-family ipv4" in BGP configurations
If you use multiprotocol BGP (MP-BGP) in your network to support MPLS VPN, IPv6 or IP Multicast over BGP, it's best if you go all the way and configure an explicit ipv4 address family; the resulting BGP configuration is significantly easier to read and understand as the session-specific parameters are clearly separated from the routing-specific parameters and the IPv4 settings are nicely grouped in an explicit section.
To change the format of the BGP configuration, configure the IPv4 address family with the address-family ipv4 unicast router configuration command (the neighbor statements and other configuration settings pertinent to IPv4 configuration are automatically moved into the new address family) or manually activate a BGP neighbor for IPv4 route exchange with the neighbor activate router configuration command.To illustrate the differences between the traditional BGP configuration and the per-address-family configuration, consider a simple MPLS VPN+Internet setup. First the traditional approach:
router bgp 65000
template peer-policy Internal
send-community both
exit-peer-policy
!
template peer-session
Internal
remote-as 65000
update-source Loopback0
exit-peer-session
!
no synchronization
bgp
log-neighbor-changes
network 10.0.1.1 mask 255.255.255.255
neighbor 10.0.1.5 inherit peer-session Internal
neighbor 10.0.1.5
description PE-C(RR)
neighbor 10.0.1.5 inherit peer-policy
Internal
no auto-summary
!
address-family vpnv4
neighbor
10.0.1.5 activate
neighbor 10.0.1.5 send-community extended
exit-address-family
... and the changed configuration after the address-family ipv4 command has been entered:
router bgp
65000
template peer-policy Internal
send-community both
exit-peer-policy
!
template peer-policy InternalV6
send-label
inherit peer-policy Internal 1
exit-peer-policy
!
template peer-session Internal
remote-as 65000
update-source Loopback0
exit-peer-session
!
bgp
log-neighbor-changes
neighbor 10.0.1.5 inherit peer-session
Internal
neighbor 10.0.1.5 description PE-C(RR)
!
address-family ipv4

network 10.0.1.1 mask
255.255.255.255

PartnerBar: Google's feed aggregating magic javascript widget thingy
I was browsing the Google AJAX Search API blog recently when I discovered they were using an interesting widget at the bottom of the page, it turned out to be PartnerBar. PartnerBar was created as an example for the Google AJAX Feed API. I have been very busy with family stuff recently so I managed to completely miss this when news of it first broke in December (Ajax Feed Partner Bar and The PartnerBar - Contextual Cross Linking). In my defence this is easy to miss, it is called "PartnerBar", which means nothing to anybody on this side of the pond and the launch article talks about "contextual cross linking" (meaningless technobabble!). Essentially, PartnerBar is a feed aggregating magic javascript widget thingy, if it had been launched as such I would have spotted it sooner.
AnywayI have been playing with it recently and have made some minor tweaks to improve it for my own usage, I'm very happy with the results. I can't decide whether to install the resulting widget permanently on my blog because I think people would find it annoying if I were to place it somewhere prominent.
My tweaks and modifications
Feed titles and links.
In the instance of PartnerBar on their blog, Google store an array of their blogs in a JavaScript file: http://www.google.com/uds/solutions/partnerbar/google-blogs.js.
Incidentally, notice how it supports tags so that you can use the same array for multiple widgets with distinct content.
My first modification was to tweak the code so that I did not have to supply the feed name and link, this information is stored in the feed (why store it twice?). To achieve this I overrode the loadPartner method - I think the trick with overriding methods in JavaScript is to make sure the method you override is a small one!
My array of blogs looks like this: blogs.js
Alternating row colours
Secondly, I wanted the feed entries to display in alternating colours. Again, I found a small JavaScript method in PartnerBar (resetClassOnPartnerDom) and overrode it (AFAIK there is no "super" keyword in JavaScript, which is a shame). In order to do this I made use of a getElementsByClassName method that I found on the web.
Final result
You should be able to see the widget in action at the top of this blog entry. However, you can link out to see the final result in standalone glory here.
Hereis my final JavaScript which my customised widget uses: partnerBar.js.
Design
Although I suffer with CSS, I am not a graphic designer and so I tend to
stealgather inspiration from elsewhere. I based my widget on the Infected table theme from the CSS table gallery.

Die Pornografinnen (Dänemark, 2005, 50mn)
ZDF
Regie: Marita Neher
Pornografie galt lange Zeit als Domäne der Männer. Frauen waren in diesem Genre nur als Objekte männlicher Begierden anzutreffen. Doch heute werden pornografische Filme, Bilder, Texte, Comics und Performances immer häufiger auch von Frauen produziert. Die Dokumentation spürt dem wachsenden Selbstverständnis nach, mit dem Frauen ihre sexuellen Fantasien und Bedürfnisse in erotischen Werken umsetzen.Nach einer weit verbreiteten Meinung werden Pornos vor allem von Männern konsumiert, nicht nur weil sie speziell für die männlichen Fantasien zugeschnitten sind, sondern weil Frauen angeblich keine entsprechenden Bedürfnisse haben. Folglich war der Pornomarkt lange Zeit ein von Männern dominierter Markt und Pornografie für viele ein Synonym für Frauenfeindlichkeit.Heute werden pornografische und erotische Werke - Filme, Texte, Fotografien, Bilder, Comics und Performances - in zunehmendem Maße auch von Frauen produziert. Es scheint, als ob Frauen nicht nur zu einem selbstverständlicheren Umgang mit Pornografie finden, sondern dabei sind, sich dieses Genre anzueignen, um ihre eigenen sexuellen Fantasien darzustellen. Welche Bilder brauchen Frauen, wenn sie sich von Pornografie erregen lassen wollen, und inwieweit unterscheiden sich von Frauen kreierte Bilder und Texte von denen männlicher Produzenten?Pornodarstellerin und -produzentin Ovidie, Fotografin Natascha Merritt, Verlegerin Claudia Gehrke, Pornoregisseurin Petra Joy sowie Elke Kuhlen und Nicole Rüdiger, Herausgeberinnen von "Glück", einem Pornoheft für Mädchen, ließen sich bei ihrer aktuellen Arbeit von der Kamera begleiten. Sie erklären, nach welchen Regeln ihrer Meinung nach Erotik und Pornografie für Frauen funktionieren. Mit Humor und Selbstironie beschreiben sie ihre sexuellen Fantasien, ihre immer noch schwierige Rolle in der Gesellschaft und die kleinen Tricks, mit denen Sexualität auf der Leinwand "echt" aussieht.Senderinfo
Erfolgsgeschichte Mobiltelefon
Schon auf der Weltausstellung 1939 in New York wurde das Konzept des Mobiltelefons im Futurama Pavillon vorgestellt. Im Zweiten Weltkrieg kommunizierten amerikanische Soldaten mobil mit Motorola Walkie Talkies. Doch es dauerte noch über 30 Jahre bis es 1973 zum legendären ersten mobilen Telefongespräch zwischen Managern von Motorola und AT&T kam. Wie sah die Entwicklung des Mobiltelefons zur Marktreife aus? Welche technischen und politischen Hürden mussten genommen werden? Die DISCOVERY CHANNEL-Dokumentation ‘Erfolgsgeschichte Mobiltelefon’ erzählt die Produktgeschichte des Mobiltelefons spannend wie ein Krimi, berichtet von Höhen und Tiefen einer technischen Revolution, die die Welt verändert hat. Bis heute wurden 2 Milliarden Mobiltelefone weltweit verkauft.

IEEE 802.1X for Wired Networks and IPSec with Microsoft Windows XP / 2003 (Microsoft Whitepaper)
IEEE 802.1X for Wired Networks and Internet Protocol Security with Microsoft Windows (Microsoft Whitepaper)
This white paper examines and compared 802.1X for wired networks and IPsec.
Download:
8021X_IPsec.doc, 2/6/2008, version 1.1
Overview:
Microsoft Windows Server 2003 and Windows XP support both the IEEE 802.1X standard for wired networks and the Internet Protocol security (IPsec) Internet standard. The IEEE 802.1X standard for wired networks provides authentication and authorization protection at the network edge where a host attaches to the network. IPsec provides peer authentication and cryptographic protection of IP traffic from end-to-end. This white paper describes the security and capabilities of 802.1X for wired networks and IPsec based on industry standards and their support in Windows Server 2003 and Windows XP, and provides comparison information when evaluating deployment of these security technologies.

Stateful Failover for IPSec (Cisco Systems)
Stateful Failover for IPSec (Cisco Systems)
Stateful failover for IP Security (IPSec) enables a router to continue processing and forwarding IPSec packets after a planned or unplanned outage occurs. Customers employ a backup (secondary) router that automatically takes over the tasks of the active (primary) router if the active router loses connectivity for any reason. This process is transparent to the user and does not require adjustment or reconfiguration of any remote peer.
Stateful failover for IPSec is designed to work in conjunction with stateful switchover (SSO) and Hot Standby Routing Protocol (HSRP). HSRP provides network redundancy for IP networks, ensuring that user traffic immediately and transparently recovers from failures in network edge devices or access circuits. That is, HSRP monitors both the inside and outside interfaces so that if either interface goes down, the whole router is deemed to be down and ownership of Internet Key Exchange (IKE) and IPSec security associations (SAs) is passed to the standby router (which transitions to the HSRP active state). SSO allows the active and standby routers to share IKE and IPSec state information so that each router has enough information to become the active router at any time. To configure stateful failover for IPSec, a network administrator should enable HSRP, assign a virtual IP address, and enable the SSO protocol.
