[c-nsp] VRF IP Helper

[Steve Mikulasik]

I am trying to setup ip helper on a 3750G 12.2(55)SE10. The SVIs are on the "GUEST" vrf and the DHCP server is in global. With "ip helper-address global 1.1.1.14" set on the SVI the switch seems to be forwarding using the SVI's IP rather than an IP in global. This behavior is different on my 3850s where an interface in global is used to forward the DHCP request.

Is there a way to set the source address for ip helper or some other method to make this work?

Here is the debug

000122: 14:36:51: DHCPD: DHCPINFORM received from client 0174.d435.b7c9.bc (172.20.1.51).
