dhcp-relay, no ip assigned when using option-82

bruno.fernandes
Level 1
Level 1

I have the following scenario (the drag is attached):

1. iosv-1 is configured has DHCP Server
2. iosv-2 is configured has relay agent for VRF A
3. G0/1 and G0/2 are on the same VRF
4. from iosv-2 I can ping iosv-1 usgin G0/2 as source
5. iosv-3 works as simple host requesting IP trough DHCP
6. iosvl2-1 as dhcp-snooping configured


The problem:
1. If I have option-82 insertion in iosvl2-1, and all interfaces are trusted for option-82 in iosv-2, I don't get an IP assignement

*Aug 22 16:05:25.753: DHCPD: cannot forward BOOTREPLY; no outbound interface. ####And I'm allways endup on this message

2. If I don't attach option-82 on iosvl2-1 than everything works !!!!


This must be somethin related with VRF integration ... I guess !!!!

Anyone with this problem ?


Thanks,
Bruno Fernandes
