Hi Shraddha, Peter, et al,
The comment on the draft I had was that the conflict case where two ISIS
routers advertise the same multi-homed prefix with a different algorithm
needs to be covered. I wouldn’t try and optimize for this and would just
do whatever is simplest but avoids loops (e.g., log the situation and
prefer the path computed with the lowest numbered algorithm).
prefix can have SIDs for many algorithms. Prefix-SID for one algorithm
is independent and orthogonal to prefix-SID for any other algorithm.
There is no need for all sources of the multi-homed prefix to include
the same set of Algo-SIDs. Each source can advertise an independent set.
The case is similar to Alg-0 SID, where prefix is advertised from two
different sources and one source advertise the Alg-0 SID and other does
not.
thanks,
Peter
