DHCP client fails to install def route on VRF interface

cjaffree2 · ‎11-11-2010

I have a 3560-48PS doing layer 3 switching and have a single VRF configured on it. The VRF contains two SVI's - one is configured with a static IP address and the other is configured to obtain its IP address via dhcp. The dhcp address is obtained, but the default route does not show up in the global or the VRF forwarding tables. I'm looking for a little insight on whether I'm missing something or if this is due to a bug.

I've dropped in configuration and version information below. Any help is greatly appreciated.
