Users Guide

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.
In BGP, the next-hop for the route is calculated from the information that is acquired through IGP or
static routes.

option for injecting/sourcing a local route in the presence of network backdoor config on a learned route.
