BGP FQDN capability not sending domain name
Open, Requires assessmentPublicBUG


Note the advertised "Hostname Capability:" neighbor capability:

[email protected]:~$ show ip bgp neighbors
BGP neighbor is, remote AS 4200000001, local AS 65001, external link
  BGP version 4, remote router ID, local router ID
  BGP state = Established, up for 00:48:38
  Last read 00:00:10, Last write 00:00:18
  Hold time is 60, keepalive interval is 20 seconds
  Neighbor capabilities:
    4 Byte AS: advertised and received
      IPv4 Unicast: RX advertised IPv4 Unicast
    Route refresh: advertised
    Address Family IPv4 Unicast: advertised and received
    Hostname Capability: advertised (name: fw1.den1,domain name: n/a) received (name: sandbox,domain name:
    Graceful Restart Capabilty: advertised

The domain name is "n/a" meaning a zero byte domain is set. However, the domain name is set in the configuration:

jma[email protected]# show system domain-name

I've filed another bug on the FQDN capability, which deals with the hostname portion after an image install + reboot, and appears unrelated to this problem.
