Usage Guidelines
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.
Examples
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
