Configuring OSPF

26

NOTE

The BigIron RX advertises the default route into OSPF even if redistribution is not enabled, and even
if the default route is learned through an IBGP neighbor. IBGP routes (including the default route)
are not redistributed into OSPF by OSPF redistribution (for example, by the OSPF redistribution
command).

In

Figure 117

on page 778, an administrator wants to configure the BigIron RX acting as the ASBR

(Autonomous System Boundary Router) between the RIP domain and the OSPF domain to
redistribute routes between the two domains.

NOTE

The ASBR must be running both RIP and OSPF protocols to support this activity.

FIGURE 117

Redistributing OSPF and static routes to RIP routes

You also have the option of specifying import of just ISIS, RIP, OSPF, BGP4, or static routes, as well
as specifying that only routes for a specific network or with a specific cost (metric) be imported, as
shown in the command syntax below:

Syntax: [no] redistribution bgp | connected | rip | static [route-map <map-name>]

RIP Domain

OSPF Domain

ASBR (Autonomous System Border Router)
