Introduced on the S4820T. Introduced on the Z9000. Introduced on the S4810. Introduced the ability to substitute IGP cost for MED when a peer/peer-group outbound route-map is set as internal. Introduced on the S-Series. Introduced on the C-Series. Usage Information You can use the redistribute command to advertise the IGP cost as the MED on redistributed routes. When you set the route-map with metric-type internal and applied outbound to an EBGP peer/peer-group, the advertised routes corresponding to those peer/peer-groups have the IGP cost set as MED. If you do not configure the 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.
