SET METRIC
set metric
Overview Use this command to add a metric set clause to a route map entry.
When a routeor BGP update message matches the route map entry, the device
takes one of the following actions:
• changes the metric(or for BGP, the MED attribute value) to the specified
value, or
• adds or subtracts the specified value from the metricor MED attribute, if you
specify
+ or - before the value (for example, to increase the metric by 2, enter
+2)
Use the no variant of this command to remove the set clause.
Syntax set metric {+< metric-value >|- <metric-value> | <metric-value> }
no set metric [+ <metric-value> |- <metric-value> | <metric-value> ]
Default The default metric value for routes redistributed into OSPF and OSPFv3 is 20.
Mode Route-map Configuration
Usage For BGP, if you want the device to compare MED values in update messages from
peers in different ASes, also enter the command
bgp always-compare-med . The
device always compares MED values in update messages from peers in the same
AS.
This command is valid for:
• OSPF routes
• routes in BGP update messages
• RIP routes.
Note that defining the OSPF metric in a route map supersedes the metric defined
using a
redistribute (OSPF) or a redistribute (IPv6 OSPF) command. For more
information, see the OSPFv3 Feature Overview and Configuration Guide and the
OSPF Feature Overview and Configuration Guide .

<metric-value> <
0-4294967295
>
The new metricor MED attribute value, or the amount by which
to increase or decrease the existing value.
