BGP AFI/SAFI numbers

[Scott Cannon]

Hi Guys,

I'm currently studying for my MPLS 642-611 exam and I was wandering if anyone could point me to a repository for BGP AFI/SAFI numbers.

Specifically, what are the AFI numbers for VPNv4 and VPNv6 addresses?

Thanks

Regards

Scott

Hello Scott,

see Table 1 in the following

http://www.cisco.com/en/US/docs/ios/12_4t/ip_route/configuration/guide/tbrbover.html

for more details look for the listed RFCs in the table

to see the AFI and SAFI fields

http://www.ietf.org/rfc/rfc2858.txt

Hope to help

Thanks for your post

Very helpful post, I have it bookmarked. AFI/SAFI allows for the MP-BGP capability.
