Hello I'm curious about the overall recommendation when selecting a small class BGP router for IPv6 (with 1gig ports). We can see the current IPv4 routing table is around 615k routes and the IPv6 routing table is sitting around ~31k routes.
In our case, we advertise a single /24 from our head office to 2 upstream providers. The routing is %100 for redundancy.
Somebody mentioned that the Brocade CER-RT was once a best seller. Brocade are now offering the CER 4X-RT version at 256K IPv6 routes supported (1.5M IPv4 routes). We don't have immediate plans for IPv6, but I do foresee this in a few year. Question is - is 256k IPv6 routes suitable?
The CER/CES NetIron boxes from Brocade are reasonable. That said, BGP-SD implementations apply both to IPv4 and IPv6. So in a Metro-E Access deployment scenario, the number of IPv6 routes would not matter, as we only download into FIB the minimum necessary to keep the box alive. Mark.
