We’re in the topic of MPLS forwarding…
My goal is to get the LFIB to report an IP prefix as Aggregate. My topology has OSPF and MPLS running. The network is completely converged between the two protocols.
R2 is an ABR and possess the ‘area 0 range 192.168.0.0 255.255.248.0′ command.
R1′s routing table:
Gateway of last resort is not set
1.0.0.0/32 is subnetted, 1 subnets
C 1.1.1.1 is directly connected, Loopback99
2.0.0.0/32 is subnetted, 1 subnets
O IA 2.2.2.2 [110/1563] via 13.0.0.2, 00:14:39, Serial0/0
3.0.0.0/32 is subnetted, 1 subnets
O IA 3.3.3.3 [110/3125] via 13.0.0.2, 00:14:17, Serial0/0
4.0.0.0/32 is subnetted, 1 subnets
O IA 4.4.4.4 [110/3125] via 13.0.0.2, 00:13:58, Serial0/0
13.0.0.0/30 is subnetted, 3 subnets
O IA 13.0.0.8 [110/3124] via 13.0.0.2, 00:15:06, Serial0/0
O IA 13.0.0.4 [110/3124] via 13.0.0.2, 00:15:06, Serial0/0
C 13.0.0.0 is directly connected, Serial0/0
O IA 192.168.0.0/21 [110/3125] via 13.0.0.2, 00:15:06, Serial0/0

I expected Aggregate, not ‘Pop Tag’. How can I get LDP to report this as being an Aggregate tag?
Thanks,
Mike
