Dot1q Tunnels & l2protocol-tunnelling question
Hi,
Is there a scenario whereby I would want to configure L2 protocol tunnelling without using IEEE 802.1q tunnelling? I’ve always used IEEE 802.1q tunnelling ie switchport mode dot1q-tunnel when tunnelling traffic across a switched network in conjunction with l2protocol-tunnel to forward cdp, vtp, lacp etc if doing etherchannel. I’ve never considered using l2protocol-tunnelling without first enabling dot1q-tunnel mode. When looking through the doc CD it says that layer 2 protocol tunneling can be used independently or can enhance IEEE 802.1Q tunneling?
– Thanks, Thor
