Frr Configuration Example - HP 12500 Series Configuration Manual

NOTE:
Configuring ordinary CR-LSP backup is almost the same as configuring hot CR-LSP backup except that you
need to replace the mpls te backup hot-standby command with the mpls te backup ordinary command.
Unlike in hot CR-LSP backup where a secondary tunnel is created immediately upon creation of a primary
tunnel, in ordinary CR-LSP backup, a secondary CR-LSP is created only after the primary LSP goes down.
Create a static route for routing MPLS TE tunnel traffic.

[SwitchA] ip route-static 20.1.1.2 24 tunnel 1 preference 1
Perform the display ip routing-table command on Switch A. You can see a static route entry with
Tunnel1 as the outgoing interface.

On a primary LSP Switch A
Switch C.
Do the following:
• Create a bypass LSP that traverses the path Switch B
Switch C is the MP.
Explicitly route the primary TE tunnel and the bypass TE tunnel with the signaling protocol being
