how to telnet from a 6513 with VRF

I"m inheriting a new network that uses a 6513 as the core switch with VRF implemented.  How do I telnet or ssh to a 3750X from the core when VRF is implemented.  Just to ping I had to use " ping vrf TRUSTED x.x.x.x".

Re: how to telnet from a 6513 with VRF

When you have a vrf, you have separate routing tables. I was basing my answer on what you were asking and thought you were needing it. Let's say that you want to ping a device in the vrf CustA. When you ping from the switch that has the vrf, you'll type "ping vrf CustA 192.168.1.50". You have to tell the switch that you're wanting to send the ping into the vrf, otherwise it tries to send it to its own global routing table.

Telnet will work the same way. You'll want to tell it that you want to telnet into a device in a certain vrf. Otherwise, it will try to route using the global routing table and not the vrf that you want.

So, if the device/host that you need to get to is in a vrf, you'll need to append/prepend the vrf tag when trying to connect to it from the switch.

How do I verify the vrf name that should be used " telnet /vrf "

Forgive my ignorance.  First time I have seen VRF.
