tunnel mpls traffic-eng autoroute metric
To specify the Multiprotocol Label Switching (MPLS) traffic engineering tunnel metric that the Interior
Gateway Protocol (IGP) enhanced shortest path first (SPF) calculation uses, use the tunnel mpls
traffic-eng autoroute metric command in interface configuration mode. To disable the specified MPLS
traffic engineering tunnel metric, use the no form of this command.
tunnel mpls traffic-eng autoroute metric {abs
olute | relative} value
no tunnel mpls traffic-eng autoroute metric
Syntax Description
Defaults The default is metric relative 0.
Command Modes Interface configuration
Command History
Examples The following example shows how to specify the use of MPLS traffic engineering tunnel metric
n
egative 1 for the IGP enhanced SPF calculation:
Router(config-if)# tunnel mpls traffic-eng autoroute metric relative -1
absolute Absolute metric mode; you can enter a positive metric value.
relative Relative metric mode; you can enter a positive, negative, or zero value.
value The metric that the IGP enhanced SPF
calculation uses. The relative value
can be from –10 to 10.
Note Even though the value for a relative metric can be from –10 to 10,
configuring a tunnel metric with a negative value is considered a
misconfiguration. If from the routing table the metric to the tunnel
tail appears to be 4, then the cost to the tunnel tail router is actually
3 because 1 is added to the cost for getting to the loopback address.
In this instance, the lowest value that you can configure for the
relative metric is –3.
