Hi ,
I am currently working on draft “draft-ietf-ccamp-gmpls-ethernet-pbb-te-03.txt” and I write this email to seek some help from experts. I have two questions regarding the Section 3 paragraph 6.
1) It say “An IB-BEB receiving a PATH message specifying one
of its CNPs can locally determine which CBPs have internal
connectivity to the I-component supporting the given CNP.”
How does the CSPF function select egress CNP, based on what criteria?
2) Further it says “On the other hand, if there is information on
the service (I-SID) that the given ESP will support, then the IB-BEB
MUST first determine which PIP and CBP is configured with the I-SID
and MUST assign that CBP to the ESP”
a) What should be action taken if ISID received in PATH message is not configured? Do I need to send PATH ERR message?
b) Assuming that I have received more than one ISID and each one belong to different CBP port, in such case what should be the behavior?
I am doing the manual configuration and association of ISID to CBP.
