Better to just run a v4 BGP mesh and a v6 BGP mesh.Ok. I've been having problems with this. What I was hoping for (even though I'm testing something that I know won't work) is that I can break something so I could push v4 traffic over a v6-only core. Is there _any_ way to do this (other than NAT/tunnel etc)?
MPLS - "The MP is for Multi Protocol!"Otherwise, no, you don't get to use IPv6 addresses as next hops for IPv4 routes, which I think is what you're asking to do.
Run IPv4 and IPv6 in parallel, iBGP for v4, iBGP for v6. Same for eBGP to peers/customers. Running v4 and v6 in one BGP session is weird and is asking for confusion, IMHO.
You get the same with OSPF - you run OSPFv2 and OSPFv3 in parallel. -- Nathan Ward
