Dell C1048P Port Extender Networking Command-Line Reference Guide for the C900 - Page 495

Version 7.8.1.0 7.7.1.0 Description Introduced on the S-Series. Introduced on the C-Series. 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. Related Commands redistribute - redistributes routes into BGP. network backdoor Specify this IGP route as the preferred route. C9000 Series Syntax network ip-address mask backdoor To remove a network, use the no network ip-address mask backdoor command.
