Although, 3.17 CCO says that it supports the feature, during testing, there as some issues, such as no pim neighborship over VRF which seems the ASR920 cannot perform neighborship with the other PE, although the other PEs see the ASR920 as a neighbor.

We have an open case with TAC for this. Also in 3.17 the IPv4 scale witth SDP IP profile is increased from 20k to 24k but it decreases some others eg. VPLS instances etc.

The ASR920 supports NG-MVPN, and we tested this.

Are you testing NG-MVPN or Rosen?
