Redistribution
Exporting routes from OSPF to RIP, and from RIP to OSPF, are discreet
configuration functions. To run OSPF and RIP simultaneously, you
must first configure both protocols and then verify the independent
operation of each. Then you can configure the routes to export from
OSPF to RIP and the routes to export from RIP to OSPF.
Redistributing Routes into OSPF. Enable or disable the exporting
of RIP and static routes to OSPF, using the following commands:
enable ospf export [static | rip] cost
{metric} [ase-type-1 | ase-type-2] {tag
}
disable ospf export [static | rip]
These commands enable or disable the exporting of RIP and static
routes by way of LSA to other OSPF routers as AS-external type 1 or
type 2 routes. The default setting is disabled.
The cost metric is inserted for all RIP-learned or static routes injected
into OSPF. The tag value is used only by special routing applications.
Use the number zero if you do not have specific requirements for
using a tag. The tag value in this instance has no relationship with
802.1Q VLAN tagging.
Verify the configuration using the command:
show ospf
Note
When redistributing RIP routes you should turn off RIP aggregation
unless you are expertly familiar with the possible consequences and
impact. By default, new configurations of RIP using switch software
version 4.0 and above disable RIP aggregation. In previous software
versions, RIP aggregation is enabled by default. This configuration is
preserved when upgrading to version 4.0. Verify the configuration
using the command
show rip .
