Re: sham link route hidden in the vpn table
even if lsas are tunneled over sham link, the forwarding is over mp-bgp/mpls. The same routes should be learned over mp-bgp and should be the ones installed on vrf's routing table. HTH

Hi, I assume the two 3850s are different logical switches.LACP will bring one of the interfaces down on the MX as the LAG is between 2 different systems. Cheers,Ashvin

The problem is not the staic LAG or LACP. You can't have the MX80 connected to two different swicthes using port aggregation unless they are stacked or they support vPC (Nexus Swicthes) or VSS. You...
