Establish IBGP peer relationships between PEs and CEs to redistribute VPN routes, and configure
4.
routing policies to change the next hop of the routes:
# On CE 1, configure PE 1 as the IBGP peer, and configure a routing policy for the routes received
from PE 1, changing the next hop address of the routes to the IP address of PE 1.

# Configure the other three CEs (CE 2 through CE 4) in a similar way to configuring CE 1. (Details

Issue the display bgp vpnv4 vpn-instance peer command on the PEs. The output shows that BGP
peer relationships have been established between the PEs and CEs, and have reached Established
state. Take the BGP peer relationship between PE 1 and CE 1 as an example:
[PE1] display bgp vpnv4 vpn-instance vpn1 peer
BGP local router ID : 1.1.1.9
Local AS number : 100
Total number of peers : 1

Configure an MP-IBGP peer relationship between PEs:
5.
# On PE 1, configure PE 2 as the MP-IBGP peer, and configure a routing policy for the routes
received from PE 2, changing the next hop address of the routes as the loopback interface address
of PE 2.
