Help in tracing VRF route

                   Hi Everyone,

From switch i am tracing destination route.

When i do traceroute it shows

traceroute 192.168.100.188

Type escape sequence to abort.

Tracing the route to 192.168.100.188

VRF info: (vrf in name/id, vrf out name/id)

  1 192.168.100.188 0 msec 0 msec 0 msec

When i do  ping to IP  it shows it learned it via  vlan 100.

When i do sh ip vrf int it does not show vlan 100.

But source vlan has vrf.

What should i check next?

Thanks

Mahesh

Help in tracing VRF route

Hi Mahesh,

Yes you are right. The interface X is a part of the VRF RC. And to check the destination IP you can use the command sh ip ro vrf RC.

Hi Mahesh,

To check the destination IP should i run this command

Yes, when you create a vrf you need to add the name of the vrf in the show commands.  For example:

if you issue "sh ip route" this will show you all the interfaces, vlans, routes in global routing table.  If you want to see routes, vlans, etc.. in a specific vrf then you issue this command:

sh ip route vrf RC

Hi Mahesh,

Can you post "sh run" from the switch?

Do you have any VRFs configured on the switch?

Help in tracing VRF route

Hi Reza,

Unfortunately i can not put sh run here.

Yes we do have vrf on switch.

Source SVI  is on this Switch.I am tracing destination from this switch.

Say source svi is x .

when i do sh ip vrf int then it shows me the

interface        IP                               VRF

x                  192.168.x.x                  RC

Does this mean that this vlan is using VRF  right?

To check the destination IP  should i run this command

SW1# sh ip route vrf RC ?
