MPLS VPN L3 BGP to Customer CPE

Hello,

I am learning how to setup MPLS VPN L3. I am running OSPF in the MPLS Core and have configured MP-BGP between PE. I am running BGP between the PE and CPE in my lab, and I can see redistributed routes from the CPE in the vrf routing table for that customer on the PE router. My question is how to reditribute the vrf routes into my MPLS core to transmit the traffic to the customer other site on the same vpn. Below is what my config looks like.

PE

------

ip vrf customerA

rd 100:101

route-target export both 100:1000

int fa0/0

ip vrf forwarding customerA

ip address x.x.x.x x.x.x.x

router ospf 1

loopback  in area0

networks in area0

router bgp 65000

neighbor to other PE routers in AS 65000 (MPLS Network)

address family vpn4

neighbor other PE routers activate

neighbor other PE routers send community

ip address ipv4 vrf customerA

neighbor to customerA in AS 55000

CPE

-------

router ospf 1

loopback in area 0

networks in area 0

router bgp 55000

neighbor to PE router in AS 65000

redistribute ospf 1

Hi

You dont have to redistribute your routes into mpls core. The vpnv4 bgp session that you have has already sent your ce routes to the remote pe router, provided you have the vrf configured on the other end.

For more detaiked explanation please check a presentation available in the current running Ask The Expert event in the support community.
