Hi All,
Currently trying to test DHCP on QinQ Sub-Interfaces on an ASR 1001-X. Static Addressing works without a hitch, but when setting the sub-interface with the DHCP Pool Default-Router address to enable a remote router to obtain an IP Address via DHCP, the 'dhcp server' receives the DHCPDISCOVER message but nothing appear to be sent to the remote router. I have included DHCP Pool, sub-interface configurations below along with 'sh ip dhcp server statistics' output and
. I would appreciate any and all advice on what I am missing!
no ip domain lookup
