While it should be obvious that you need to have an interface up and going
to run BGP anyway...  But more importantly, in case you're a nuveau adopter
of IPv6, you need to have either an IPv4 interface up and running or
manually specify a router id.  Routing protocols right now are using 32-bit
router-id values which correspond nicely to IPv4, but not to IPv6!

So do "show ip interface brief" and see what's up and running.

GS,

I cannot think of  a logical reason for the error below, never encountered
it before and bgp running fine without hardcoding a router-id, now its
asking for it.
Any ideas?

TIA

configure manually.
