changed to SHOULD.

RFC8379 specifies how to advertise the local/remote interface ID for the 
purpose of identifying the link by the remote routers. It does not 
suggest to use the Extended Link Opaque LSA as a discovery mechanism to 
find out what is the interface ID on the remote side of the link.

removed.
