configure mpls rsvp-te profile (fast-reroute)

configure mpls rsvp-te profile frr_profile_name {bandwidth bandwidth_rate_bps bandwidth_rate_unit} {detour {hop-limit hop_limit_value} {bandwidth-protection [enabled | disabled]} {node-protection [enabled | disabled]}} {hold-priority hold_priority_value} {setup-priority setup_priority_value}

Description

Configures the specified RSVP-TE FRR profile.

Syntax Description

frr_profile_name	Specifies the FRR LSP profile to configure.
bandwidth_rate_ bps	Specifies the bandwidth requirement for the FRR LSP. This should be set to match the options chosen for the protected LSP. Otherwise, a mismatch between the bandwidth settings for the detour and protected LSPs can impact service.
bandwidth_rate_ unit	Specifies the units for the bandwidth rate. Valid entries are Kbps, Mbps, and Gbps.
detour	Specifies the detour method of fast reroute. This is the only method supported in this release.
hop_limit_value	Specifies the maximum number of hops that the detour path is allowed to take from the current node or point of local repair (PLR) to a merge point (MP) node. If set to 0, only link protection is provided.
bandwidth-protection	When enabled, this option specifies that the signaled bandwidth on the detour path must be guaranteed. If this option is disabled, the detour path might not support the bandwidth needed for the protected LSP.
node-protection	When enabled, the this option indicates to the PLRs along a protected path that a detour path that bypasses at least the next node of the protected LSP is desired. If this option is disabled, the backup path might or might not bypass the next node, in which case the user might or might not have next-node protection.
hold-priority	Specifies the hold priority of the LSP. Lower numbers indicate higher priority. The range is from 0 to 7. Hold priority is used when deciding whether a session can be preempted by another session. This works exactly the same as the hold-priority set in the standard profile that is valid for the protected LSP and for standard LSPs.
setup-priority	Specifies the setup priority of the LSP. Lower numbers indicate higher priority. The range is from 0 to 7. The setup priority is used when deciding whether the detour LSP can preempt another session. This works exactly the same as the setup-priority set in the standard profile that is valid for the protected LSP and standard LSPs.

Default

Bandwidth: Newly-created profiles are configured as best-effort. Setup-priority: 7 (lowest) Hold-priority: 0 (highest) Hop-limit: 3 Protect-bandwidth: enabled Protect-node: enabled

Usage Guidelines

A FRR profile is a set of attributes that are applied to the detour and protected LSPs when a protected LSP is configured. A default profile (frr-default) is provided which cannot be deleted, but can be applied to any protected LSP. The maximum number of configurable profiles is 1000.

Note

Changing any of the profile parameters causes LSPs using the profile to be torn down and re-signaled. There is no guarantee that the re-signaled LSP will be successfully established. Future ExtremeXOS implementations may support the make-before-break LSP concept.

Example

The following command configures the FRR profile frrprofile for 100 Mbps bandwidth:

configure mpls rsvp-te profile frrprofile bandwidth 100 Mbps

History

This command was first available in ExtremeXOS 12.1.

Platform Availability

This command is available only on the platforms that support MPLS (Multiprotocol Label Switching) as described in the ExtremeXOS 22.7 Feature License Requirements document.
