III. Configuration procedure
1) Configure CE1
# Configure CE1 and PE1 as neighbors, redistribute directly connected routes and
static routes to redistribute intra-CE1 VPN routes into BGP and advertise to PE1. CE1
connects PE1 through Ethernet0.
[CE1] interface ethernet 0/0/0
[CE1-Ethernet0/0/0] ip address 168.1.1.1 255.255.0.0
[CE1-Ethernet0/0/0] quit
[CE1] bgp 65410
[CE1-bgp] group 168 external
[CE1-bgp] peer 168.1.1.2 group 168 as-number 100
[CE1-bgp] import-route direct
[CE1-bgp] import-route static
Note:
The configuration of other three CEs (CE2~CE4) is similar, so it is not mentioned here.
2) Configure PE1.
