HP HSR6800 Configuration Manual page 331

This example uses OSPF. Be sure to advertise the route to the 32-bit loopback interface
address of each router through OSPF. The loopback interface address of a router is to be used
as the router's LSR ID. (Details not shown.)
After the configurations, each ASBR PE and the PE in the same AS can establish OSPF
adjacencies. Execute the display ospf peer command. The output shows that the adjacencies
reach Full state, and that each ASBR PE and the PE in the same AS can learn 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 MPLS LDP on the MPLS backbone to establish LDP LSPs:
# Configure basic MPLS on PE 1 and enable MPLS LDP on the interface connected to ASBR
PE 1.
<PE1> system-view
[PE1] mpls lsr-id 1.1.1.9
[PE1] mpls
[PE1-mpls] quit
[PE1] mpls ldp
[PE1-mpls-ldp] quit
[PE1] interface pos 5/1/1
[PE1-POS5/1/1] mpls
[PE1-POS5/1/1] mpls ldp
[PE1-POS5/1/1] quit
# Configure basic MPLS on ASBR PE 1 and enable MPLS LDP on the interface connected to
PE 1.

# Configure basic MPLS on ASBR PE 2 and enable MPLS LDP on the interface connected to
PE 2.
