Status Change for RFC 7506 – “IPv6 Router Alert Option for MPLS Operations, Administration, and Maintenance (OAM)” to historic.

RFC 7506 allocated IPv6 Router Alert Option (RAO) value that can be used by the MPLS Echo Request and MPLS Echo Reply messages for MPLS in IPv6 environments.

The Router Alert Option for IPv4 environments was specified by RFC 8029.

draft-ietf-mpls-lsp-norao retires the RAO for MPLS OAM for both IPv4 and IPv6 environments. The document updates RFC 8029 to remove the RAO from MPLS Echo Request and Echo Reply message encapsulations. Furthermore, draft-ietf-mpls-lsp-norao explains why RFC 7506 should be marked historic.

This status change document marks RFC 7506 as historic.
