R211x-HP Flexfabric 11900 MPLS Configuration Guide

223
# Execute the display ospf peer command to verify that OSPF adjacencies in Full state have been
established between each ASBR-PE and the PE in the same AS, and that PE and ASBR-PE routers in
the same AS have learned the routes to the loopback interfaces of each other.
Each ASBR-PE and the PE in the same AS can ping each other.
2. Configure basic MPLS and enable MPLS LDP on each MPLS backbone to establish LDP LSPs:
# Configure basic MPLS on PE 1, and enable MPLS LDP for the interface connected to ASBR-PE 1.
<PE1> system-view
[PE1] mpls lsr-id 1.1.1.9
[PE1] mpls ldp
[PE1-ldp] quit
[PE1] interface vlan-interface 11
[PE1-Vlan-interface11] mpls enable
[PE1-Vlan-interface11] mpls ldp enable
[PE1-Vlan-interface11] quit
# Configure basic MPLS on ASBR-PE 1, and enable MPLS LDP for the interface connected to PE 1.
<ASBR-PE1> system-view
[ASBR-PE1] mpls lsr-id 2.2.2.9
[ASBR-PE1] mpls ldp
[ASBR-PE1-ldp] quit
[ASBR-PE1] interface vlan-interface 11
[ASBR-PE1-Vlan-interface11] mpls enable
[ASBR-PE1-Vlan-interface11] mpls ldp enable
[ASBR-PE1-Vlan-interface11] quit
# Configure basic MPLS on ASBR-PE 2, and enable MPLS LDP for the interface connected to PE 2.
<ASBR-PE2> system-view
[ASBR-PE2] mpls lsr-id 3.3.3.9
[ASBR-PE2] mpls ldp
[ASBR-PE2-ldp] quit
[ASBR-PE2] interface vlan-interface 11
[ASBR-PE2-Vlan-interface11] mpls enable
[ASBR-PE2-Vlan-interface11] mpls ldp enable
[ASBR-PE2-Vlan-interface11] quit
# Configure basic MPLS on PE 2, and enable MPLS LDP for the interface connected to ASBR-PE 2.
<PE2> system-view
[PE2] mpls lsr-id 4.4.4.9
[PE2] mpls ldp
[PE2-ldp] quit
[PE2] interface vlan-interface 11
[PE2-Vlan-interface11] mpls enable
[PE2-Vlan-interface11] mpls ldp enable
[PE2-Vlan-interface11] quit
# Each PE and the ASBR-PE in the same AS can establish an LDP neighbor relationship. Execute the
display mpls ldp peer command on the switches. The output shows that the session status is
Operational.
3. Configure a VPN instance on the PEs:
For the same VPN, the route targets for the VPN instance on the PE must match those for the VPN
instance of the ASBR-PE in the same AS. This is not required for PEs in different ASs.
