Arista MPLS VPN Step by Step (1d) MPLS L3VPN PE/CE OSPF

In this post I will discuss the PE/CE routing option - OSPF. Here is the simplified topology



PE Configuration:

router bgp 65001
....
   vrf pe1-ospf
      rd 100:110
      route-target import vpn-ipv4 100:110
      route-target import vpn-ipv4 200:110
      route-target export vpn-ipv4 100:110
      maximum-paths 2 ecmp 2
      redistribute connected
      redistribute ospf
!
router ospf 100 vrf pe1-ospf
   router-id 88.255.11.11
   passive-interface Loopback103
   redistribute bgp
   network 100.100.110.11/32 area 0.0.0.0
   network 100.250.110.11/32 area 0.0.0.0
   max-lsa 12000

CE Configuration:

router ospf 100 vrf ce1-ospf
   router-id 100.250.100.100
   passive-interface Loopback103
   network 100.100.110.1/32 area 0.0.0.0
   network 100.255.110.1/32 area 0.0.0.0
   max-lsa 12000
