Bgp Always-Compare-Med - Dell C9000 Series Reference Manual

If the route is injected via the network command, that route still appears in the routing
table if the summary-only parameter is configured in the aggregate-address
command.
The summary-only parameter suppresses all advertisements. If you want to suppress
advertisements to only specific neighbors, use the neighbor distribute-list
command.
In the show ip bgp command, aggregates contain an 'a' in the first column and
routes suppressed by the aggregate contain an 's' in the first column.

bgp always-compare-med
