Hi Jason, ME3600 does support tunnelling of l2 control frames on xconnect EVCs, these are a snippets of config from our network:
service instance 2020 ethernet encapsulation default l2protocol tunnel service-policy input PM-CUST-DEFAULT-200M-BD-IN service-policy output PM-CUST-DEFAULT-200M-OUT xconnect 10.123.143.1 134300001 encapsulation mpls mtu 9000 ! service instance 1602 ethernet encapsulation dot1q 1602 second-dot1q 3655 rewrite ingress tag pop 1 symmetric l2protocol tunnel service-policy input PM-CUST-DEFAULT-10M-BD-IN service-policy output PM-CUST-DEFAULT-10M-OUT xconnect 10.123.114.1 144200001 encapsulation mpls mtu 9000 We use this if the other side has a layer 2 CPE that does tunnelling as well. If the customer is directly connected to a PE we normally use 'l2protocol forward'. kind regards Pshem On 30 October 2013 17:15, Jason Lixfeld <[email protected]> wrote: > As far as what I can glean from various configuration guides and other bits > of documentation: > > ME3600s don't support L2 protocol tunneling on cross-connect EVCs, but they > do on port based xconnects or on EVCs where the sp-facing interfaces are > trunks; they will forward, tunnel or peer various layer 2 protocols.
