We are about to start advertising our ipv6 space with our upsteam provider next week. We already have an existing ipv4 bgp session operational. If my reading is correct all we will be doing is setting up a new peer with ipv6 enabled, using the assigned ipv6 remote address, and adding the ipv6 address space to networks. Am I missing anything?
You can simply enable ipv6 address family to existing ipv4 peer.
That’s VERY bad practice. Separate peers for IPv4 and IPv6.
You should have a separate IPV6 peer for BGP. You announce IPV6 over the V6 peer.
Separate peers as you may want to apply different filters.
Be sure to create basic IPV6 firewall rules to keep the bad packets out and let BGP in
