Currently have BGP running between multiple routers.
IP6 is enabled on them, although not being used, yet.

if I just add an ip 6 address to a router it doesn't advertise the address to any of its peers, like an ip4 address does.
need to know .. do I just need to enable ip6 in the address family on each bgp peer?

or is it required that I also re-setup the peering on ip6 numbers between the routers also?
also because I'm peering using the loopback address . do I need to add another ip6 address to the loopback?

Most providers will do two separate peering sessions for IPv4 and IPv6. You can request a single one, but each provider will have their own policy for this.

this is acutaly internal bgp I'm running. so i'm trying to get the peers to route it dynamically ,
so It sounds like I should be running 2 peering sessions one for ip4 and one of ip6?

You can do it only with one peering session. In peer config set both address families ip and ipv6

ok I have done that and it shows that the routes are advertised .. but in BGP advertisements it says next hop 0.0.0.0
and the routes don't propagate into the ip6 routing table.
is there more to be done than just enableing the ip6 family option?

Thanx
