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 Gateway of last resort is not set C 192.168.1.0/24 is directly connected, Ethernet1/0 C 192.168.2.0/24 is directly connected, Ethernet1/1 R 192.168.5.0/24 [120/1] via 192.168.2.2, 00:00:15, Ethernet1/1 R 192.169.1.0/24 [120/1] via 192.168.2.2, 00:00:15, Ethernet1/1 R 192.169.2.0/24 [120/1] via 192.168.2.2, 00:00:15, Ethernet1/1 R 200.1.1.0/24 [120/1] via 192.168.2.2, 00:00:15, Ethernet1/1 RT1# - Route Redistribution from RIP into EIGRP configuration on RT2: RT2(config)#router eigrp 2 RT2(config-router)#redistribute rip metric ?

- The configuration above defines 2000 bandwidth metric, 200 microseconds delay, and considers all links to be 100% reliable and have minimum traffic for all routes redistributed from RIP. EIGRP route redistribution configuration requires configuring all the composite metric values. - Note: The subnet mask of the route to the Frame Relay network is /24 instead of /29. This is because EIGRP has summarized the route to its classful boundary. Additionally, classful routing protocols (eg: RIP) which do not understand VLSM and CIDR would drop the routing updates. - Below shows the routing table on RT5 to verify the RIP is properly redistributed into EIGRP: RT5#sh ip route Gateway of last resort is not set D EX 192.168.1.0/24 [170/2221056] via 200.1.1.1, 00:15:30, Serial0/0 D EX 192.168.2.0/24 [170/2221056] via 200.1.1.1, 00:15:30, Serial0/0 C 192.168.5.0/24 is directly connected, Ethernet1/0 D 192.169.1.0/24 [90/2195456] via 200.1.1.1, 00:08:15, Serial0/0 D 192.169.2.0/24 [90/2195456] via 200.1.1.2, 00:08:15, Serial0/0 C 200.1.1.0/29 is directly connected, Serial0/0 RT5# - Route Redistribution from EIGRP into IGRP configuration on RT4: RT4(config)#router igrp 1 RT4(config-router)#redistribute eigrp 2 metric 2000 200 255 1 1500 RT4(config-router)# - Route Redistribution from IGRP into EIGRP configuration on RT4: RT4(config)#router eigrp 2 RT4(config-router)#redistribute igrp 1 metric 2000 200 255 1 1500 RT4(config-router)# - Below shows the routing table on RT3 to verify the EIGRP is properly redistributed into IGRP: RT3#sh ip route Gateway of last resort is not set I 192.168.1.0/24 [100/8776] via 192.168.4.2, 00:00:30, Ethernet1/1 I 192.168.2.0/24 [100/8776] via 192.168.4.2, 00:00:30, Ethernet1/1 C 192.168.3.0/24 is directly connected, Ethernet1/0 C 192.168.4.0/24 is directly connected, Ethernet1/1 I 192.168.5.0/24 [100/8676] via 192.168.4.2, 00:00:30, Ethernet1/1 I 192.169.1.0/24 [100/8676] via 192.168.4.2, 00:00:30, Ethernet1/1 I 192.169.2.0/24 [100/1200] via 192.168.4.2, 00:00:30, Ethernet1/1 I 200.1.1.0/24 [100/8576] via 192.168.4.2, 00:00:30, Ethernet1/1 RT3# - Note: All RIP routes are also shown in RT3 routing table, as the RIP routes have been redistributed into EIGRP at RT2. So when EIGRP routes are being redistributed into IGRP at RT4, all the RIP routes are being redistributed into IGRP as well. 206 Copyright © 2008 Yap Chin Hoong yapchinhoong@hotmail.com
