# Execute the display mpls te tunnel command on Router A. You can see that only the tunnel
traversing Router D is present:
[RouterA] display mpls te tunnel
LSP-Id Destination In/Out-If Name
1.1.1.9:2054 3.3.3.9 -/POS5/1/1 Tunnel3
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.
6. Create a static route to direct traffic to the MPLS TE tunnel:
[RouterA] ip route-static 20.1.1.2 24 tunnel 3 preference 1
Execute the display ip routing-table command on Router A. You can see a static route entry with
Tunnel 3 as the outgoing interface.
FRR configuration example
Network requirements
On the LSP Router A Router B Router C Router D, use FRR to protect the link Router B Router C.→→ → →
Create a bypass LSP that traverses the path Router B Router E Router C. Router B is th→→ e PLR and Router
C is the MP.
Explicitly route the primary TE tunnel and the bypass TE tunnel with the signaling protocol being RSVP-TE.
