I'd be interested in hearing if people set a hostname on their BGP
routers and send it to peers (internal and/or external).
I'm also interested in hearing if you see external peers sending it to
you.
Yes and yes. We see a few route server operators (Netnod and Verizon) to
be specific advertise it to us. We find it useful, as it makes the
neighbour summary more human readable for those peers, as we do not have
to remember their IP addresses and/or AS numbers to know which peer it
is at a glance:
$ show bgp ipv4 unicast vrf internet summary
