PE 3
Configuration procedure
1. Configure basic MPLS L3VPN:
Configure OSPF on the MPLS backbone to allow the PEs and P device to learn the routes of the loopback
interfaces from each other.
Configure basic MPLS and MPLS LDP on the MPLS backbone to establish LDP LSPs.
Establish MP-IBGP peer relationships between the PEs to advertise VPN IPv4 routes.
Configure VPN 1 on PE 1 to allow CE 1 to access the network.
Configure VPN 1 on PE 2 to allow CE 2 to access the network.
Configure VPN 1 on PE 3 to allow CE 3 to access the network.
Configure BGP between PE 1 and CE 1, between PE 2 and CE 2, and between PE 3 and CE 3 to inject
routes of CEs into PEs.
2. Configure BGP AS number substitution:
# Configure BGP AS number substitution on PE 1, PE2, and PE3 as described in
BGP AS number
# Display routing information on CE 2. You can see that CE 2 has learned the route
100.1.1.1/32 to CE 1. A routing loop has occurred because CE1 and CE 2 reside in the same
site.
<CE2> display bgp routing-table peer 10.2.1.2 received-routes
Total Number of Routes: 8
BGP Local router ID is 10.2.1.1
Status codes: * - valid, ^ - VPN best, > - best, d - damped,

3. Configure the SoO attribute:
# On PE 1, configure a routing policy named soo to add the specified SoO attribute.

# On PE 1, apply the routing policy soo to routes received from CE 1.
