[PE1-bgp] quit
# Configure PE 2 in a similar way to configuring PE 1. (Details not shown.)
# Execute the display bgp peer command or the display bgp vpnv4 all peer command on the PEs.
The output shows that a BGP peer relationship has been established between the PEs, and has
reached Established state.

6. Configure a GRE tunnel:
# Configure PE 1.
[PE1] interface tunnel 0
[PE1-Tunnel0] tunnel-protocol gre
[PE1-Tunnel0] source loopback 0
[PE1-Tunnel0] destination 2.2.2.9
[PE1-Tunnel0] ip address 20.1.1.1 24
[PE1-Tunnel0] mpls
[PE1-Tunnel0] quit
# Configure PE 2.
[PE2] interface tunnel 0
[PE2-Tunnel0] tunnel-protocol gre
[PE2-Tunnel0] source loopback 0
[PE2-Tunnel0] destination 1.1.1.9
[PE2-Tunnel0] ip address 20.1.1.2 24
[PE2-Tunnel0] mpls
[PE2-Tunnel0] quit
7. Verify the configuration:
After the configurations, the CEs can learn the interface routes from each other. Take CE 1 as an
example:
[CE1] display ip routing-table
Routing Tables: Public

10.2.1.0/24 BGP 255 0 10.1.1.2 GE2/1/1
127.0.0.0/8 Direct 0 0 127.0.0.1 InLoop0
127.0.0.1/32 Direct 0 0 127.0.0.1 InLoop0
Take PE 1 as an example:
[PE1] display ip routing-table
