To specify that the traffic engineering router identifier for the node is the IP address associated with a
given interface, use the mpls traffic-eng router-id command in router configuration mode. To remove
the traffic engineering router identifier, use the no form of this command.

Syntax Description

Command Modes Router configuration
Command History
Usage Guidelines This router identifier acts as a stable IP address for the traffic engineering configuration. This IP address
i
s flooded to all nodes. For all traffic engineering tunnels originating at other nodes and ending at this
node, you must set the tunnel destination to the traffic engineering router identifier of the destination
node, because that is the address that the traffic engineering topology database at the tunnel head uses
for its path calculation.
You should configure the same traffic engineering router id for all Interior Gateway Protocol (IGP)
ro
uting processes.
Examples The following example shows how to specify the traffic engineering router identifier as the IP address
a
ssociated with interface Loopback0:
Router(config-router)# mpls traffic-eng router-id Loopback0
