R3303-HP HSR6800 Routers MPLS Configuration Guide
329
After the configuration, LDP sessions are established between Spoke-PE 1 and Hub-PE, and
between Spoke-PE 2 and Hub-PE. Execute the display mpls ldp session command. The output
shows that the session status is Operational. Execute the display mpls ldp lsp command. The output
shows the LSPs established by LDP.
Take Spoke-PE 1 as an example:
[Spoke-PE1] display mpls ldp session
LDP Session(s) in Public Network
Total number of sessions: 1

3. Configure VPN instances on the spoke-PEs and the hub-PE to allow CEs to access the PEs:
# Configure Spoke-PE 1.
[Spoke-PE1] ip vpn-instance vpn1
[Spoke-PE1-vpn-instance-vpn1] route-distinguisher 100:1
[Spoke-PE1-vpn-instance-vpn1] vpn-target 111:1 import-extcommunity
[Spoke-PE1-vpn-instance-vpn1] vpn-target 222:2 export-extcommunity
[Spoke-PE1-vpn-instance-vpn1] quit
[Spoke-PE1] interface gigabitethernet 2/1/1
[Spoke-PE1-GigabitEthernet2/1/1] ip binding vpn-instance vpn1
[Spoke-PE1-GigabitEthernet2/1/1] ip address 10.1.1.2 24
[Spoke-PE1-GigabitEthernet2/1/1] quit
# Configure Spoke-PE 2.
[Spoke-PE2] ip vpn-instance vpn1
[Spoke-PE2-vpn-instance-vpn1] route-distinguisher 100:2
[Spoke-PE2-vpn-instance-vpn1] vpn-target 111:1 import-extcommunity
[Spoke-PE2-vpn-instance-vpn1] vpn-target 222:2 export-extcommunity
[Spoke-PE2-vpn-instance-vpn1] quit
[Spoke-PE2] interface gigabitethernet 2/1/1
[Spoke-PE2-GigabitEthernet2/1/1] ip binding vpn-instance vpn1
[Spoke-PE2-GigabitEthernet2/1/1] ip address 10.2.1.2 24
[Spoke-PE2-GigabitEthernet2/1/1] quit
# Configure the Hub-PE.
