What i am trying to do is DHCP from Clients through MSAN on VLAN 213 . What i notice seems that DHCP Server (ASR 9000) Does not response to DHCP Discover from Clients. I am not sure if my vlan config between the device is still not correct or my DHCP Server config which is not inlude here. However when i capture on the ME3800 interface te0/1 connecting to the Cisco ASR 9000 i can see the clients Discover seems not reach the Server.

 

Appreciate any help regarding this. I can post the rest of my DHCP config if it can help , but i guess maybe my VLAN config is the issue but i am not sure that is why i post here
