Ios-xr ldp

up2thetime

Hey everyone,

Was looking for a little help with LDP on IOS-XRv. I have two routers connected via their Gi0/0/0/0 interfaces. XR1 connects directly to XR2. They are able to establish an OSPF Adjacency and pass routes to each other. The problem is, LDP neighbours will not form. I followed the configuration in the IOS-XR Fundamentals Guide:

configure terminal
mpls ldp
router-id Loopback1
interface Gi0/0/0/0
commit

That configuration has been applied on both routers. I know multicasts are reaching each other due to OSPF establishing, however I am not sure why the won't become LDP neighbours. I also tried the auto-cofigure method mentioned in the guide.

The OSPF config is as follows:
router ospf 1
router-id 1.1.1.1 and 2.2.2.2 (for XR2)
area 0
interface Loopback 1
network point-to-point
interface Gi0/0/0/0
network point-to-point

I also tried removing the point-to-point OSPF interface configuration, but that still did not work.

Any ideas?

Thanks!

That's the output of show mpls ldp discovery and show mpls ldp interface?

Thanks for pointing out the discovery command! Found out there was no route to the neighbour router-id. Routing issue.

Thanks again.
