from

Configures only the local interface of the routing device. The command penalizes any link on the specified interface, but not all links when the link is a multi-access link.

Syntax

from ip_addr
no from ip_addr

Command Default

The command is disabled, by default.

Parameters

ip_addr
Specifies the selected IP address of the fate sharing group

Modes

MPLS CSPF-group configuration mode (config-router-mpls-cspf-group-group_name)

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

Usage Guidelines

The order in which the local IP address to the remote IP address is configured is insignificant. For example, the configuration from 10.10.10.10 to 10.20.20.20 and from 10.20.20.20 to 10.10.10.10 has the same meaning.

The user can configure an interface level from IP address for a dynamic bypass LSP to be created for the protected MPLS interface. Dynamic bypasses use the from address as the IP address.

The no form of the command removes the from-address and is set to default.

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

Examples

The following example configures the local address 10.1.1.1 of the fate sharing group.

device# configure
device(config)# router mpls
device(config-router-mpls)# cspf-group group3
device(config-router-mpls-cspf-group-group3)# from 10.1.1.1

The following example configures the from address 11.11.11.11 for dynamic bypass MPLS Ethernet interface 0/8.

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)# from 11.11.11.11
