peter,
two questions:
1) how do you know that the other side will be accepting the T-LDP session at a
non loopback IP address ?
I'm proposing to use OSPF router-id as a first choice. In any reasonable
deployment, that address belongs to loopback interface.
If OSPF router-id can not be used, then there is no way currently to
tell which of the /32s advertised by PQ node belong to loopbacks.
Operator have two choices:
- make sure that the highest /32 address advertised by PQ node is a
loopback address
- use some local policy on the calculating node to pick the address on
the PQ node that work with LDP.
2) what is your proposed scheme for minimizing the amount of T-LDP sessions
between a pair of routers ?
I do not see how the IP address used for T-LDP peering makes an impact
on the number of LDP sessions used for rLFA between any pair of routers.
There should only be one session used for rLFA between any pair of routers.
thanks,
Peter
(is it numerically highest IP ?)
