Configuring OSPF
The
The default is 100. For 10 Gbps OSPF interfaces, in order to differentiate the costs between 100
Mbps, 1000 Mbps, and 10,000 Mbps interfaces, set the auto-cost reference bandwidth to 10000,
whereby each slower link is given a higher cost
To restore the reference bandwidth to its default value and thus restore the default costs of
interfaces to their default values, enter the following command.
TurboIron(config-ospf-router)#no auto-cost reference-bandwidth
Define redistribution filters
Route redistribution imports and translates different protocol routes into a specified protocol type.
On routers, redistribution is supported for static routes, OSPF, RIP, and BGP4. When you configure
redistribution for RIP, you can specify that static, OSPF, or BGP4 routes are imported into RIP
routes. Likewise, OSPF redistribution supports the import of static, RIP, and BGP4 routes into OSPF
routes. BGP4 supports redistribution of static, RIP, and OSPF routes into BGP4.
NOTE
The Layer 3 Switch 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 redistribute
command).
In
on page 630, an administrator wants to configure the Layer 3 Switch 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.
To configure for redistribution, define the redistribution tables with deny and permit redistribution
filters. Use the deny and permit redistribute commands for OSPF at the OSPF router level.
