Redistributing Routes Into Ospf - Motorola BSR 2000 Configuration And Management Manual

Release 1.0
Example
The following example creates the OSPF routing process and adds two OSPF ranges
(123.3.4.0 and 125.6.6.0) with each range belonging to a different area. Area 0 is
configured for 123.3.4.0 and Area 1 is configured for 125.6.6.0.The example creates
two OSPF interfaces. One interface is in the backbone area (Area 0) using IP address
123.3.4.17. The other interface is in the non-backbone area (Area 1) using IP address
125.6.6.23.

Redistributing Routes into OSPF

Each routing protocol uses different metrics to transfer routes. Some protocols use
hop count metrics, while others use bandwidth and delay attributes to define metrics.
When a specific route is redistributed from one routing protocol or domain into
another, a common metric must be applied by the receiving protocol. Routes are
redistributed to advertise networks on another routing protocol.
Follow these steps to redistribute routes into OSPF:
1. Enter the OSPF routing process in which the routes are to be redistributed:
2. Choose from one or more of the following options to redistribute routes from a

•
Use the redistribute bgp command in Router Configuration mode to
redistribute BGP routes into OSPF:
MOT (config-ospf)#redistribute bgp [metric <1-16777214> |
route-map <WORD> | <cr> ]
where:
1-16777214 is the redistribution metric number for BGP routes.
WORD is the BGP route-map name.
cr is a command return that redistributes all BGP routes.
•
Use the redistribute connected command in Router Configuration mode to
redistribute connected routes into OSPF:
