RE: Cisco MC-LAG

I just read this... " Its implementation varies by vendor. "

http://en.wikipedia.org/wiki/MC-LAG

MC-LAG, or Multi-Chassis Link Aggregation Group, is a type of LAG with
constituent ports that terminate on separate chassis, thereby providing
node-level redundancy. Unlike link aggregation in general, MC-LAG is not
covered under IEEE 802.1AX-2008. Its implementation varies by vendor.

Dude

I doubt anyone would have hands on experience with this, best you sniff and
see if non vendor devices speak the same language.

Hi Sirhan

The CEs talk to each other over (VLL on the upstream and VPLS downstream
connection-DUAL connection) So at Layer 2 do not have VRRP as an option My
question is am seing what looks like compatibility issues between Cisco
MC-LAG and a non-cisco device so wanted to confirm is cisco MC-LAG works
well with other vendors. I have this working well with a single chasis cisco
ASR and two non-cisco devices.
