Description (partial)

Symptom:
The OMP default route will not be redistributed and advertised in BGP

Conditions:
Below are the configurations and the output.

router bgp 65311
 bgp router-id 2.1.88.30
 bgp log-neighbor-changes
address-family ipv4 vrf 1
  bgp router-id 2.1.88.30

The same default route is not seen in the BGP table.
