R3303-HP HSR6800 Routers MPLS Configuration Guide

Verifying the configuration:

# Execute the display mpls static-lsp command on each router to view static LSP information. Take

Router A as an example:

[RouterA] display mpls static-lsp

total statics-lsp : 2

Name FEC I/O Label I/O If State

AtoC 21.1.1.0/24 NULL/30 -/S2/1/0 Up

CtoA -/- 70/NULL S2/1/0/- Up

# On Router A, test the connectivity of the LSP from Router A to Router C.

[RouterA] ping lsp -a 11.1.1.1 ipv4 21.1.1.0 24

LSP Ping FEC: IPV4 PREFIX 21.1.1.0/24 : 100 data bytes, press CTRL_C to break

Configuring LDP to establish LSPs dynamically

Network requirements

Router A, Router B, and Router C support MPLS.

Configure LDP to establish LSPs between Router A and Router C so that subnets 11.1.1.0 / 24 a n d

21.1.1.0/24 can reach each other over MPLS. Test the connectivity of the LSPs.
