# Configure PE3.
[PE3] mpls lsr-id 4.4.4.4
[PE3] mpls
[PE3-mpls] quit
[PE3] mpls ldp
[PE3-ldp] quit
[PE3] interface pos 1/0/0
[PE3-Pos1/0/0] mpls
[PE3-Pos1/0/0] mpls ldp
[PE3-Pos1/0/0] quit
[PE3] interface pos 2/0/0
[PE3-Pos2/0/0] mpls
[PE3-Pos2/0/0] mpls ldp
[PE3-Pos2/0/0] quit
After the preceding configuration, LDP sessions are set up between PEs. Run the display mpls
ldp session command. The command output shows that the Status field displays Operational.
Step 4 Configure VPN instances on PE1 and PE2 so that CE1 can access both PEs.
# Configure PE1.
[PE1] ip vpn-instance vpna
[PE1-vpn-instance-vpna] route-distinguisher 100:1
[PE1-vpn-instance-vpna] vpn-target 111:1 both
[PE1-vpn-instance-vpna] quit
[PE1] interface vlanif 10
[PE1-vlanif10] ip binding vpn-instance vpna
[PE1-vlanif10] ip address 10.1.1.2 24
[PE1-vlanif10] quit
# Configure PE2.
[PE2] ip vpn-instance vpna
[PE2-vpn-instance-vpna] route-distinguisher 100:2
[PE2-vpn-instance-vpna] vpn-target 111:1 both
[PE2-vpn-instance-vpna] quit
[PE2] interface vlanif 10
[PE2-vlanif10] ip binding vpn-instance vpna
[PE2-vlanif10] ip address 10.1.1.3 24
[PE2-vlanif10] quit
Step 5 Enable EFM OAM extension between PE1 and CE1, and between PE2 and CE1.
# Configure PE1.
[PE1] efm enable
[PE1] interface gigabitethernet 3/0/0
[PE1-GigabitEthernet3/0/0] efm enable
[PE1-GigabitEthernet3/0/0] efm trigger if-down
[PE1-GigabitEthernet3/0/0] quit
# Configure PE2.
[PE2] efm enable
[PE2] interface gigabitethernet 3/0/0
[PE2-GigabitEthernet3/0/0] efm enable
[PE2-GigabitEthernet3/0/0] efm trigger if-down
[PE2-GigabitEthernet3/0/0] quit
Step 6 Configure the static routes on PE1 and PE2 that are destined for CE1, and import the static routes
to the Border Gateway Protocol (BGP).
# Configure PE1.
[PE1] ip route-static vpn-instance vpna 1.1.1.1 32 10.1.1.1
[PE1] bgp 100
[PE1-bgp] ipv4-family vpn-instance vpna
