Issue Pint connectivity

Hi Team,


WE are facing in our network that we have bgp peering with Alcatel router Point to Point.When we try to ping the IP,we are not able to ping but while we ping with the source of any interface ,we were able to ping the remote IP.PLease help to suggest the way forward.


<KARBLRHTR01>display bgp peer ipv4 vpn-instance OAM

 BGP local router ID:
 Local AS number: 65521
 Total number of peers: 2                 Peers in established state: 2

Re: Issue Pint connectivity

I notice that the ping that works comes from a different IP subnet to the routing address - against i take it as you are trying to ping

How is your subnet set up? Are the 2 routing interfaces in different subnets or the same subnet? If they are in the same subnet are you just not routing as the switch/router that is the source is not forwarding the packets due to the subnetting?

Just a thought.
