The bestroute igp-metric-ignore command configures BGP to ignore the IGP metric when selecting the optimal route.
The undo bestroute igp-metric-ignore command restores the default configuration.
By default, BGP uses the IGP metric as one of route selection rules.

Usage Scenario
On a BGP network, the router often receives multiple routes with the same prefix but different paths from different peers. To forward traffic to that prefix address, BGP needs to select an optimal route from these routes. By default, BGP will compare the IGP metrics of these routes to their BGP next hops and select a route with the smallest IGP metric.
The bestroute igp-metric-ignore command can be run to configure BGP to ignore the IGP metrics in route selection based on customers' routing requirements.
Configuration Impact
After the bestroute igp-metric-ignore command is run, BGP does not compare the IGP metrics of routes to BGP next hops.
