Hi,
We have a hub and spoke scenario in which a route from spoke is stopped
from advertising to RR. RR is not receiving the route but still it
advertises to the hub routers (peer groups). Following is the output taken
in RR where the route is no more received from anywhere but still
advertises to some peer-group.

VRR-R-1#sh bgp vpnv4 unicast rd 93:8156 57.236.254.240/29
BGP routing table entry for 93:8156:57.236.254.240/29, version 1235597754
Paths: (0 available, no best path)
Flag: 0x820
  Advertised to update-groups:
     1          3          4          7          8
VRR-R-1#


What is underlying problem here?



Warm Regards,
Thiyagarajan B
