Deployment Guide

Border Gateway Protocol IPv4 (BGPv4) | 379
If you do not configure default-metric command, in addition to the redistribute command, or there is no
route map to set the metric, the metric for redistributed static and connected is “0”.
To redistribute the default route (0.0.0.0/0) configure the neighbor default-originate command.
As BGP does not query next-hop information corresponding to locally originated routes, a local route
with an unreachable next-hop is chosen as the best route.
When a combination of locally originated and peer originated routes occurs, both these routes will
exist in the RTM. However, only the best route is kept active in the RTM and the remaining route is
rendered in-active.
It is possible to keep only one locally originated route in the BGP database. Network command has
preference over the re-distributed routes. When the locally originated route is no longer present in the
database the other route is automatically installed.
