Hi ,
I am seeing MPLS TE Tunnel is not coming up in my setup.
I am using XRV node running version 7.11.2. I have explained below the config and status.
Could anyone please check and comment on this issue ?

Add LO to ospf abd check

Hi @MHM Cisco World ,
Kindly check my ospf config. Lo0 is added already. Am i missing anything else here ?
router ospf 1
router-id 92.168.96.24
redistribute connected
address-family ipv4 unicast
area 0.0.0.0
mpls traffic-eng
interface Loopback0
ā05-08-2024 10:15 AM
Run
Mpls ldp
In both ios xr
And LO I see you use 0.0.0.0 that sure cover LO IP
MHM
ā05-08-2024 12:33 PM
I still suspect about LO and opsf
Remove redistribute connect since the te use LO as ip unnumbered.
Waiting your reply hope this solution fot this issue
MHM

Hi @MHM Cisco World ,
The fact that the loopback interface is not advertised in ospf had nothing to do with it. Look at the configs I included. I do not advertise the loopback in ospf. I do not redistribute the connected routes either. This is not required.

ā05-08-2024 12:48 PM
The LO use as unnumbered IP and use as destination and he run ospf redistribute connected (lo and TE is conneced)
All of above make mpls label not correct work
I Think he need only remove redistribute connect and issue will solve

Could you check my configs and my results before making any further comments.

Hi @mailatgk ,
I quickly loaded your configs in XRv9k 7.11.1 and it works like a charm.

Sorry you mentioned you run his config and you dont use redistribute connect and that improves my idea the redistribute connect is issued here.
Anyway let wait his reply
Thanks

Redistribute connected doesn't have anything to do with the tunnel not coming up. It will work with or without.
