Usage Guidelines

Usage Scenario

The bestroute med-none-as-maximum command takes effect in MBGP route selection and is used only when no MED is in the route attributes.

Configuration Impact

During MBGP route selection, if the bestroute med-none-as-maximum command is run, a route without any MED is assigned the maximum MED of 4294967295.

Precautions

If no MED is in the route attributes and the bestroute med-none-as-maximum command is not run, the system probably cannot select an optimal route.

Example

# Configure MBGP to assign the maximum MED of 4294967295 to a route without an MED in route selection.
