BGP MCAST-VPN Route Types

Registration Procedure(s)

  • Standards Action

Reference

  • RFC 7441: Encoding Multipoint LDP (mLDP) Forwarding Equivalence Classes (FECs) in the NLRI of BGP MCAST-VPN Routes
  • RFC 6514: BGP Encodings and Procedures for Multicast in MPLS/BGP IP VPNs

Note

Values may be assigned from one of several ranges:

  • Range 0x01-0x3f: Generic/PIM Range. Values are assigned from this range when the NLRI format associated with the route type presupposes that PIM or IGMP is the C-multicast control protocol, or when the NLRI format associated with the route type is independent of the C-multicast control protocol.

  • Range 0x43-0x7f: mLDP Range. Values are assigned from this range when the NLRI format associated with the route type presupposes that mLDP is the C-multicast control protocol.

  • Range 0x80-0xff: This range is reserved; values should not be assigned from this range.

In general, whenever an assignment is requested from this registry, two codepoints should be requested at the same time: one from the Generic/PIM range (0x01-0x3f) and one from the mLDP range (0x43-0x7f). The two codepoints should have the same low-order 6 bits. If one of the two codepoints is not actually needed, it should be registered anyway, and marked as "Reserved."
