Modifying redistribution parameters

This device 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 lookups
The recursive next-hop lookups feature is disabled by default.
To enable recursive next-hop lookups, enter the following command at the BGP configuration level
of the CLI.
BigIron RX(config-bgp)# next-hop-recursion
Syntax: [no] next-hop-recursion
Modifying redistribution parameters
By 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, directly
connected routes, or static routes into BGP4.
To enable redistribution of all OSPF routes and directly attached routes into BGP4, enter the
following commands.
BigIron RX(config)# router bgp
BigIron RX(config-bgp)# redistribute ospf
BigIron RX(config-bgp)# redistribute connected
BigIron RX(config-bgp)# write memory
Syntax: [no] redistribute connected | ospf | rip | isis | static
The connected parameter indicates that you are redistributing routes to directly attached devices
into BGP.
The ospf parameter indicates that you are redistributing OSPF routes into BGP4.
NOTE
Entering redistribute ospf simply redistributes internal OSPF routes. If you want to redistribute
external OSPF routes also, you must use the redistribute ospf match external... command. Refer to
“Redistributing OSPF external routes” on page 785.
NOTE
When a route-map, prefix-list, or as-path ACL is modified, BGP will be notified. Outbound route
polices will be updated automatically. No longer requires user to manually clear neighbor
soft-outbound. If the filter is used by BGP inbound route policies, a manual clear of a neighbor is still
required.
The rip parameter indicates that you are redistributing RIP routes into BGP4.
The isis parameter indicates that you are redistributing ISIS routes into BGP4.
The static parameter indicates that you are redistributing static routes into BGP.
