Arista MPLS VPN Step by Step (1e) MPLS L3VPN PE/CE ISIS

Now it is the PE/CE routing option - ISIS. Here is the simplified topology



PE1 Configuration:

router bgp 65001

   !

   vrf pe1-isis

      rd 100:115

      route-target import vpn-ipv4 100:115

      route-target import vpn-ipv4 200:115 << import PE2's routes

      route-target export vpn-ipv4 100:115 << pe1=100:115, pe2=200:115

      maximum-paths 2 ecmp 2

      redistribute connected

      redistribute isis level-2

   redistribute bgp

   !

   address-family ipv4 unicast

CE Configuration:

router isis isis-ce1 vrf ce1-isis

   net 47.0001.0001.0001.0001.00

   is-type level-2
