Hello All,
could anyone explain to me why there is a need to configure QinQ in this task? We are tunneling "L3" etherchannel, for there is no tagging involved at the 2 ends. A simple tunneling should do it for this task, which also will not trigger the need to change the mtu size.
Here is my config:
====================================================
SW1
interface range gigabitEthernet 1/0/17, gigabitEthernet 1/0/20
switch access vlan 100
l2protocol-tunnel cdp
switchport mode access
interface range gigabitEthernet 1/0/18, gigabitEthernet 1/0/21
switch access vlan 101
l2protocol-tunnel cdp
switchport mode access
====================================================
Thanks in advance.
