distance (BGP and BGP4+)
Overview This command sets the administrative distance for BGP and BGP4+ routes. The
device uses this value to select between two or more routes to the same
destination from two different routing protocols. Set the administrative distance
for BGP routes in the Router Configuration mode, and for BGP4+ routes in IPv6
Address Family Configuration mode.
The route with the smallest administrative distance value is added to the
Forwarding Information Base (FIB). For more information, see the
Route Selection
Feature Overview and Configuration Guide , which is available from the above link
at alliedtelesis.com.
The no variant of this command sets the administrative distance for the route to
the default for the route type.
