Hi,

'

What is the major difference between these two commands:


ping vrf ABC 192.10.2.2

ping vrf ABC 192.10.2.2 source vlan 6


I am able to ping a voice server from 6509 router with the second command but not with the first one.There is just one vlan(vl 6) is configured in this vrf.


and imp to note,im able to ping other boice server with the 1st command itself,i.e. without source vlan 6.


Please tell me the difference and possible reason for this to happen

Hi,

This is smply a routing issue.


ping vrf ABC 192.10.2.2 <-- Using this command your source IP will be the IP of exit interface throught which the route for

host is learned (in your case 192.10.2.2)


If you are learning the route for 192.10.2.2 from interface e0/0 and the ip of interaface e0/0 is 1.1.1.1


ping vrf ABC 192.10.2.2 = ping vrf ABC 192.10.2.2 source 1.1.1.1


In your case you dont have proper routing between 192.10.2.2 & 1.1.1.1
