Enables facility backup (many-to-one) Fast Reroute (FRR) on a Label Switched Path (LSP).
By default, a FRR LSP is a one-to-one (detour) protection LSP with the desired node protection.
MPLS router LSP FRR configuration mode.
When enabled at every Point of Local Repair (PLR), the LSP outgoing interface is expected to be protected by a bypass LSP. The user can create bypass LSPs manually or they can be created automatically using dynamic bypass.
The no form of the command sets the FRR LSP to the detour (one-to-one) mode.
MPLS is supported on the Extreme 8820, SLX 9740, SLX 9640, and SLX 9540 devices only.
The following example enables facility backup on LSP named my-fbkup-lsp.
device# kconfigure device(config)# router mpls device(config-router-mpls)#lsp my-fbkup-lsp device(config-router-mpls-lsp-my-fbkup-lsp)# frr device(config-router-mpls-lsp-my-fbkup-lsp-frr)# facility-backup
