Route Redistribution Configuration
- Route redistribution redistributes routes from the source protocol into the destination protocol,
which is achieved by entering the router configuration mode for the destination protocol and
followed by the redistribute router subcommand to bring in the routes of the source protocol.
- The redistribute {protocol} {as-num | process-id} {metric} router subcommand is used to
redistributes routes from one routing protocol to another routing protocol.
- The as-num parameter is applicable only to routing protocols that use AS number identifiers, eg:
IGRP and EIGRP; while the process-id parameter is applicable only to OSPF.
- RT2 is the boundary of for RIP and EIGRP, while RT4 is the boundary of IGRP and EIGRP.
These are the places to redistribute routes between routing domains (or protocols).
- Route Redistribution from EIGRP into RIP configuration on RT2:
RT2(config)#router rip
RT2(config-router)#redistribute eigrp 2 metric 1
RT2(config-router)#
- The configuration above set all routes coming from EIGRP AS 2 as 1 hop count since RIP uses
hop counts as the metric.
- Below shows the routing table on RT1 to verify the EIGRP is properly redistributed into RIP:
RT1#sh ip route
