Bfd For Lsp Configuration Example - HP HPE FlexNetwork MSR Router Series Configuration Manual

BFD for LSP configuration example

Network requirements
Use LDP to establish an LSP from 1.1.1.9/32 to 3.3.3.9/32 and an LSP from 3.3.3.9/32 to 1.1.1.9/32.
Use BFD to verify LSP connectivity.

Configuration procedure
1. Configure IP addresses for interfaces. (Details not shown.)
2. Configure OSPF to ensure IP connectivity between the routers:
# Configure Router A.
<RouterA> system-view
[RouterA] ospf
[RouterA-ospf-1] area 0
[RouterA-ospf-1-area-0.0.0.0] network 1.1.1.9 0.0.0.0
[RouterA-ospf-1-area-0.0.0.0] network 10.1.1.0 0.0.0.255
[RouterA-ospf-1-area-0.0.0.0] quit
[RouterA-ospf-1] quit
# Configure Router B.
<RouterB> system-view
[RouterB] ospf
[RouterB-ospf-1] area 0
[RouterB-ospf-1-area-0.0.0.0] network 2.2.2.9 0.0.0.0
[RouterB-ospf-1-area-0.0.0.0] network 10.1.1.0 0.0.0.255
[RouterB-ospf-1-area-0.0.0.0] network 20.1.1.0 0.0.0.255
[RouterB-ospf-1-area-0.0.0.0] quit
[RouterB-ospf-1] quit
# Configure Router C.
<RouterC> system-view
[RouterC] ospf
[RouterC-ospf-1] area 0
[RouterC-ospf-1-area-0.0.0.0] network 3.3.3.9 0.0.0.0
[RouterC-ospf-1-area-0.0.0.0] network 20.1.1.0 0.0.0.255
[RouterC-ospf-1-area-0.0.0.0] quit
[RouterC-ospf-1] quit
3. Enable MPLS and LDP:
# Configure Router A.
[RouterA] mpls lsr-id 1.1.1.9
[RouterA] mpls ldp
[RouterA-ldp] quit
