On page 5, draft-ietf-sidr-bgpsec-protocol-11 says: A BGP speaker SHOULD NOT advertise the capability of BGPsec support for a particular AFI unless it has also advertised the multiprotocol extension capability for the same AFI combination [3].
I interpret this to mean that if a BGPsec speaker intends to send IPv4 updates to a peer, it should advertise multiprotocol extension capability with AFI = 1. That is so even when it intends to send only IPv4 updates. The fact that multiprotocol extension capability (with AFI = 1) is advertised, does it mean that MP_REACH_NLRI (see page 3, RFC 4760) should be used for announcing IPv4 prefixes? Just trying to clarify because it wasn’t clear to me reading RFC 4760.
