Hello All,
I have a simple topology with a few XE routers running SR-MPLS in each ISIS domain. PE1 and PE2 are acting as ASBRs. Between PE1 and PE2, I’m running BGP-LU and VPNv4 AF.
The issue I’m facing is that the label assigned by BGP-Labeled Unicast is not from the SRGB block.
Here’s a traceroute from R1 (in AS1) to R5 (in AS2):
R1#traceroute 5.5.5.5
1 10.10.10.2 [MPLS: Labels 10003/17/10005 Exp 0]
2 10.10.23.2 [MPLS: Labels 17/10005 Exp 0]
Looking the MPLS label range, I can see the label falls under the downstream generic label region, but it's not what I expected to see.
PE2# show mpls label range
Downstream Generic label region: Min/Max label: 16/1048575
Range for Reserved labels:
1. Range ID: 0 Owner: SR-APP
Min/Max label: 10000/13000

Thank you in advanced,
