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

Thanks for your post

 

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