Usage
Information
The software compares the MEDs only if the path contains no external
autonomous system numbers. If you enable this command, use the
clear ip
bgp *
command to recompute the best path.
bgp bestpath med missing-as-best
During path selection, indicate preference to paths with missing MED (MULTI_EXIT_DISC) over paths with
an advertised MED attribute.

Usage
Information
The MED is a 4-byte unsigned integer value and the default behavior is to assume a
missing MED as 4294967295. This command causes a missing MED to be treated
as 0. During path selection, paths with a lower MED are preferred over paths with a
higher MED.
bgp bestpath router-id ignore
Do not compare router-id information for external paths during best path selection.
Syntax
bgp bestpath router-id ignore
To return to the default selection, use the
no bgp bestpath router-id
ignore
command.
