BGP

More notes after the fact…. It was surprisingly easy actually. Started out on Torix.  Most everything locally can be had via the route servers.  One small annoying thing… Who the hell came up with

show ipv6 bgp sum

Whoever decided that syntax has either super long fingers, or does not type that combo of keys (v then 6) very much…  Try it…. ipv6… ipv6.  When you are debugging pathing issues, you have to type it a lot and its very annoying!

Total number of neighbors 6

A full view is only about 3000 routes

In terms of config, there is not a hell of a lot more than plain old bgp4

 address-family ipv6
 network 2607:f3e0::/32
 neighbor 2001:5a0:1000:200::5 activate
 neighbor 2001:5a0:1000:200::5 remove-private-AS
 neighbor 2001:5a0:1000:200::5 soft-reconfiguration inbound
 neighbor 2001:5a0:1000:200::5 prefix-list SENTEX-INET6 out
 neighbor 2001:5a0:1000:200::5 route-map TELEGLOBE-6-OUT out

In terms of dealing with peers it was fairly straight forward. Cogent was very easy. “Hey, I want IPV6 transit”… “Sign this paper” and that was that. A week later I had the info and was ready to go. TATA (6453) was a lot more paperwork and back and forth, but once I dealt with the ipnoc folks it was easy enough as they were pretty clueful. The peers at Torix were also easy to deal with. he.net is probably the most IPv6 gung ho org out there. They have a lot of tutorials and links aggregated into one location which I will write about later
