[j-nsp] Re : juniper - cisco l2circuit problem

[hritter at videotron.ca]

Christian,

If you want to use EoMPLS xconnect on a SVI (to allow for local switching as well) then you need a OSM+/SIP400/SIP600/ES20 as the core facing interface. Without one of these modules, you can only configure the xconnext on a sub-interface or main interface.

Hope this helps,
