hop-limit

Gives the ability to change the hop limit to a lower number.

Syntax

hop-limit number
hop-limit number

Command Default

By default, there is no hop-limit configuration .

Parameters

number
Specifies the selected number of hops in the path. The range for the number of hops is 0 - 255 with a default number of 255.

Modes

MPLS LSP configuration mode (config-router-mpls-lsp-lsp_name).

MPLS router bypass LSP configuration mode (config-router-mpls-bypass-lsp-bypass_name).

MPLS router MPLS interface dynamic bypass configuration mode (config-router-mpls-if-ethernet-slot/port-dynamic-bypass)

Usage Guidelines

The no form of the command removes the specified number of hops and returns to the default hop number of 255 hops.

The user can configure an interface level hop-limit for dynamic Bypass LSPs to be created corresponding to a protected link.

Compute the dynamic bypass path, so the hop-limit is the minimum number of the backup requested hop limit and the interface mode configured hop limit. This computed hop limit sets as the dynamic bypass LSP hop limit during the initial creation of dynamic bypass.

MPLS is supported on the Extreme 8820, SLX 9740, SLX 9640, and SLX 9540 devices only.

Examples

The following example limits the CSPF to choosing a path consisting of no more than 20 hops for LSP tunnel1 .

device# configure
device(config)# router mpls
device(config-router-mpls)# lsp tunnel1
device(config-router-mpls-lsp-tunnel1)# hop-limit 20

The following example configures the bypass LSP hop limit to 6.

device# configure
device(config)# router mpls
device(config-router-mpls)# bypass-lsp my-bypass-lsp
device(config-router-mpls-bypass-lsp-my-bypass-lsp)#  hop-limit 6

The following example configures dynamic bypass MPLS Ethernet interface 0/8 s hop-limit to 5 .

device# configure
device(config)# router mpls
device(config-router-mpls)# mpls-interface ethernet 0/8
device(config-router-mpls-if-ethernet-0/8)# dynamic bypass
device(config-router-mpls-if-ethernet-0/8-dynamic-bypass)# hop-limit 5
