Section 4 says:
Address Family Identifier (AFI): This field in combination with the Subsequent Address Family Identifier field identifies the set of Network Layer protocols to which the address carried in the Next Hop field must belong, the way in which the address of the next hop is encoded, and the semantics of the Network Layer Reachability Information that follows. If the Next Hop is allowed to be from more than one Network Layer protocol, the encoding of the Next Hop MUST provide a way to determine its Network Layer protocol. Presently defined values for the Address Family Identifier field are specified in the IANA's Address Family Numbers registry [IANA-AF]. Subsequent Address Family Identifier (SAFI): This field in combination with the Address Family Identifier field identifies the set of Network Layer protocols to which the address carried in the Next Hop must belong, the way in which the address of the next hop is encoded, and the semantics of the Network Layer Reachability Information that follows. If the Next Hop is allowed to be from more than one Network Layer protocol, the encoding of the Next Hop MUST provide a way to determine its Network Layer protocol.
It should say:
Address Family Identifier (AFI): This field in combination with the Subsequent Address Family Identifier field identifies the semantics of Withdrawn Routes Network Layer Reachability Information carried in the attribute. Presently defined values for the Address Family Identifier field are specified in the IANA's Address Family Numbers registry [IANA-AF]. Subsequent Address Family Identifier (SAFI): This field in combination with the Address Family Identifier field identifies the semantics of Withdrawn Routes Network Layer Reachability Information carried in the attribute.
Notes:
This original text refers to the field (Next Hop) that is not present in
the attribute MP_UNREACH_NLRI. Therefore the original text is not applicable.
