LSP-Id Destination In/Out-If Name
1.1.1.9:2054 3.3.3.9 -/Vlan4 Tunnel1
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.
6. 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.
FRR configuration example
Network requirements
On a primary LSP Switch A Switch B Switch C → → Switch D, use FRR to protect the link Switch B → →
Switch C.
• Create a bypass LSP that traverses the path Switch B Switch E Switch C. Switch B is the PLR and → →
Switch C is the MP.
• Explicitly route the primary TE tunnel and the bypass TE tunnel with the signaling protocol being
RSVP-TE.
