The plan is to explicitly allow such retractions in RFC 6126-bis, but they are clearly not allowed by RFC 6126.
Hmm, the RFC says this (which I seem to have previously missed):
If the metric field is FFFF hexadecimal, this TLV specifies a retraction. In that case, the current router-id and the Seqno are not used. AE MAY then be 0, in which case this Update retracts all of the routes previously advertised on this interface.
Okay, actually trying to put this into code: Is the intention here that a null-router ID update is acceptable only on *wildcard* retractions or on *all* retractions? -Toke
