Hi Frederick,
In the current operation of TE OSPF, the LSRs at each end of a TE link
emit LSAs describing the link.The databases in the LSRs then have two
entries (one locally generated, the other from the peer)that describe the
different 'directions' of the link.
For the inter-AS link, there
Dear JP,
Thanks for your good question, and we'll consider this in the next
version.
For the scenarios that there are serveral Inter-AS links between two ASes,
if all of them do not satisfy the constraints, PCE will return PCRep with
NOTH-PATH object, and the PCReq will not be relayed.
Dear JP,
There maybe several inter-AS links between two adjacent ASes, so we just
selected some of them that can satisfy the constraints in both of the
directions. Of cause, if all of the inter-as links can not satisfy the
constraints, PCE will stop relying as you say,and will reply an PCRep
