Usage
Information
Dell Networking OS software resolves the network address the network command
configures with the routes in the main routing table to ensure that the networks are
reachable using non-BGP routes and non-default routes.
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.
In BGP, the next-hop for the route is calculated from the information that is
acquired through IGP or static routes.
