z Two Switch 8800s serve as PE devices, which support MPLS feature. CE-1 and
CE-2 are two mid-range switches; a Layer 2 switch serves as both CE-3 and CE-4,
which is accessed directly with users.
z Two PEs are configured with the same interface cards: Slot 2 holds the common
interface card with FE ports (B card) and slot 3 holds the enhanced interface card
with GE ports (C card).

III. Configure procedure
1) Configure CE-1
Create EBGP neighborhood between CE-1 and PE 1, import direct-connect routes and
static routes to import the VPN routes inside CE-1 to BGP and to advertise to PE 1, link
CE-1 to PE 1 through the Ethernet0/1/0 port.
[CE1] interface ethernet 0/1/0
[CE1-Ethernet0/1/0] ip address 20.1.1.1 255.255.0.0
[CE1-Ethernet0/1/0] quit
[CE1] bgp 65410
[CE1-bgp] group 20 external
[CE1-bgp] peer 20.1.1.2 group 20 as-number 100
[CE1-bgp] import-route direct
[CE1-bgp] import-route static
 Note:
The configuration on CE-2 is similar to that on CE-1, so its detailed configuration is
omitted here.
2) Configure PE 1
Configure VPN-instance.
