Hello Deccan, MALLIK and Shahram,
I want to understand why do we need this? When BFD bootstrapping is
completed then we use local discr (BFD packet your discr) as a key which will
be unique with in the local system. Please take a look at below section of RFC
5880.
https://tools.ietf.org/html/rfc5880#section-6.3
We don’t need to really use any other fields as we would have exchanged the
discr using LSP ping. I might have misunderstood your question and would like
to be corrected.
Thanks

Hi Mallik
Source address is also a good method. But it is better to form as standard.
thanks

Hi,
I think the question is 2 different ingress LSRs using the same FEC, LSP,
Discriminator values. Discriminator values can be the same for 2 different
ingress LSRs and if the other values are same we can always use the Source
address to differentiate. Am I missing something?
Regards
Mallik

Hi
Why can't the ingress allocate different LD to each of those BFD sessions?

hi authors
It is neccessary to address the case that different ingress LSR establish BFD
session with the same egress LSR, with same FEC, same local descriminator.
I think it is very useful to introduce a BFD Initiator TLV to LSP ping echo
request message, to distinguish different ingress LSR. So that ingress allocate
LD based on tuple <FEC, LSP> as defined in this draft, but egress allocate LD
based on tuple <Initiator, FEC, RD>.
thanks
