•
If you select a less restrictive filter, mLDP initiates a wildcard label request in order to install the mLDP
label bindings that were denied earlier.
•
Creating an RPL policy that allows filtering based on the recursive FEC content is not supported.
•
Applying an RPL policy to configuration commands impacts the performance to a limited extent.
Next-Generation Multicast VPN
Next-Generation Multicast VPN (NG-MVPN) offers more scalability for Layer 3 VPN multicast traffic. It
allows point-to-multipoint Label Switched Paths (LSP) to be used to transport the multicast traffic between
PEs, thus allowing the multicast traffic and the unicast traffic to benefit from the advantages of MPLS transport,
such as traffic engineering and fast re-route. This technology is ideal for video transport as well as offering
multicast service to customers of the layer 3 VPN service.
NG-MVPN supports:
•
VRF Route-Import and Source-AS Extended Communities
•
Upstream Multicast Hop (UMH) and Duplicate Avoidance

Leaf AD (Type-4) and Source-Active (Type-5) BGP AD messages
