Having a hard time figuring this out. I have a vrf with around 30k prefixes (partial Internet.)Sup720-3BXL shows: RTR-2#sh mls cef summary detail Total routes: 58231 IPv4 unicast routes: 29043 IPv4 non-vrf routes: 89 IPv4 non-vrf routes (internal): 0 IPv4 vrf routes: 28943 IPv4 vrf routes (internal): 11 IPv4 Multicast routes: 5 MPLS routes: 28849 IPv6 unicast routes: 330 IPv6 non-vrf routes: 6 IPv6 non-vrf routes (internal): 0 IPv6 vrf routes: 69 IPv6 vrf routes (internal): 255 IPv6 multicast routes: 3 EoM routes: 1 What are "IPv4 vrf routes" as opposed to "MPLS routes"?
The box will generate and advertise a distinct MPLS LSP for each route which has a next-hop, plus one overall label for the VRF aggregate, for "connected" routes.
That is, these 4 routes: 192.168.1.0/24 -> 192.168.100.100 192.168.2.0/24 -> 192.168.100.100 192.168.3.0/24 -> connected 192.168.4.0/24 -> connected ...will generate 3 MPLS labels: 192.168.1.0/24 -> label=98 192.168.2.0/24 -> label=99 192.168.3.0/24 -> VRF agg. label=100 192.168.4.0/24 -> VRF agg. label=100 So you'll burn a lot of MPLS labels
Looks like the prefixes count twice from a fib perspective. Is that correct?
