No need to replace the sentence. It is left on implementations to supply ASP-UP with ASP-id using any available method, whether it is static reconfiguration or dynamic reconfiguration etc. The ASP Identifier can't just be pulled out of thin air. > For it to be useful the value needs to be known to all the > ASP using the same routing context. agreed ...

SG rejects ASP-UP only in the case when it has invalid ASP-id. Please see the example of invalid ASP-ID in RFC(4666) section 3.8.1 David > > Registered Address Lakeside, Bramley Road, Mount Farm, Milton Keynes, MK1 > 1PT, UK > Registration No: 1397386 (Wales) > P Please consider the environment and don't print this e-mail unless you > really need to > > _______________________________________________ > Sigtran mailing list > [email protected] > https://www.ietf.org/mailman/listinfo/sigtran > Cheers, Ankit _______________________________________________ Sigtran mailing list [email protected] https://www.ietf.org/mailman/listinfo/sigtran
