Re: [Linux-vrf-general] Help needed

Hi jeongholee,

Thanks for reverting back to me.

Yeah I am running  ssh and telnet server on VRF 0, and I would like 
to tell you one more thing here is, when I am doing traceroute -d <IP 
of my VRF 1 (eth1)>, from VRF 2 (eth2), I am getting the error 
"Network is unreachable" and Socket operation is failed, but I can 
run the simple traceroute successfully.

Thanks
Rajeev Bansal.
