set metric [ +relValue | -relValue | absValue ]
no set metric
Command introduced before JUNOSe Release 7.1.0.
Modifies the metric value (for BGP, the MED) for a route that matches the route map by applying a relative or absolute metric. The no version removes the set clause from a route map.
Note: You cannot have an absolute and a relative metric within the same route map sequence. Issuing either command overrides any previously configured metric in the route map.
