If it’s 100% for redundancy, why not just ECMP defaults and not take a full table?

That will allow you to use a MUCH cheaper router with a much simpler configuration.

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?

Thanks
Dave
