776 BigIron RX Series Configuration Guide53-1001986-01Modifying redistribution parameters26This BigIron RX can use this route because the device has an IP route to the next-hop gateway.Without recursive next-hop lookups, this route would not be in the IP route table.Enabling recursive next-hop lookupsThe recursive next-hop lookups feature is disabled by default.To enable recursive next-hop lookups, enter the following command at the BGP configuration levelof the CLI.BigIron RX(config-bgp)# next-hop-recursionSyntax: [no] next-hop-recursionModifying redistribution parametersBy default, the router does not redistribute route information between BGP4 and the IP IGPs (RIP,ISIS, and OSPF). You can configure the router to redistribute OSPF, ISIS, or RIP routes, directlyconnected routes, or static routes into BGP4.To enable redistribution of all OSPF routes and directly attached routes into BGP4, enter thefollowing commands.BigIron RX(config)# router bgpBigIron RX(config-bgp)# redistribute ospfBigIron RX(config-bgp)# redistribute connectedBigIron RX(config-bgp)# write memorySyntax: [no] redistribute connected | ospf | rip | isis | staticThe connected parameter indicates that you are redistributing routes to directly attached devicesinto BGP.The ospf parameter indicates that you are redistributing OSPF routes into BGP4.NOTEEntering redistribute ospf simply redistributes internal OSPF routes. If you want to redistributeexternal OSPF routes also, you must use the redistribute ospf match external... command. Refer to“Redistributing OSPF external routes” on page 777.NOTEWhen a route-map, prefix-list, or as-path ACL is modified, BGP will be notified. Outbound routepolices will be updated automatically. No longer requires user to manually clear neighborsoft-outbound. If the filter is used by BGP inbound route policies, a manual clear of a neighbor is stillrequired.The rip parameter indicates that you are redistributing RIP routes into BGP4.The isis parameter indicates that you are redistributing ISIS routes into BGP4.BigIron RX# show ip route 240.0.0.0/24Total number of IP routes: 38Network Address Gateway Port Cost Type240.0.0.0 10.0.0.1 1/1 1 BAS_PATH: 65001 4355 1
