Hi everybody,
I am testing how we can use BFD for LSP. for some reason, it is not working .
Set up:
MX1-g0/0/0-----g0/0/0 -MX2-ge001--ge0/0/1 MX3
MX1 has lo0:1.1.1.1, MX3 has lo0: 3.3.3.3
I statically configured RSVP LSP to 3.3.3.3 on MX1 , which is up.
But I noticed MX1 is sending BFD probes to 127.0.0.0 instead of 3.3.3.3
root@MX1> show bfd session
Detect Transmit
Address State Interface Time Interval Multiplier
127.0.0.1 AdminDown ge-0/0/0.0 0.150 1.000 2
Capture taken between MX1 and MX2 confirms MX1 is not sending BGP messages to 3.3.3.3, but 127.0.0.1
How can I tell MX1 to send BFD probe to 3.3.3.3 not to 127.0.0.1 ?
Thanks and have a good day!!
