facility-backup

Enables facility backup (many-to-one) Fast Reroute (FRR) on a Label Switched Path (LSP).

Syntax

Command Default

By default, a FRR LSP is a one-to-one (detour) protection LSP with the desired node protection.

Parameters

bandwidth: Specifies the bandwidth for the detour or backup LSP.
exclude-any name: Excludes any of the specified administrative groups.
hop-limit num: Specifies the limit of hops the detour or backup LSP can traverse.
include-all: Specifies to include all of the administrative groups.
include-any: Specifies to include any of the administrative groups.
link-protection: Requests link protection for the LSP.
priority: Requests setup and hold priorities.
revertive: Activates FRR revertiveness.

Modes

MPLS router LSP FRR configuration mode.

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 only on devices based on the DNX chipset family. For a list of such devices, see "Supported Hardware".

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
