In this lab we will see how to configure route redistribution between RIP and EIGRP. We use Route Distribution because Route Redistribution allows routes from one routing protocol to be advertised into another routing protocol.It helps network admin to make it possible to communicate between different routing protocols.It is also possible to redistribute from one routing protocol to the same routing protocol, such as between two separate OSPF domains (distinguished by unique process ID’s). Static routes and connected interfaces can be redistributed into a routing protocol as well.  While configuring route redistribution Routing metrics are a key consideration.

Step 1:Assign ip address on router interfaces.

Step 2:Configure RIP Routing on R1:

r1(config)#router rip

r1(config-router)#version 2

r1(config-router)#network 1.0.0.0

r1(config-router)#network 3.0.0.0

r1(config-router)#exit

r1(config)#do write

Building configuration...

[OK]

r1(config)#

Step3: configure RIP and EIGRP on Router r2:

 

r2(config)#router rip

r2(config-router)#version 2

r2(config-router)#network 3.0.0.0

r2(config-router)#exit

r2(config)#do write

Building configuration...

[OK]

r2(config)#

 

EIGRP on R2

r2(config)#router eigrp 1

r2(config-router)#network 4.0.0.0

r2(config-router)#exit

r2(config)#do write

Building configuration...

[OK]

r2(config)#

Step4: configure EIGRP on Router R3:

 

r3(config)#router eigrp 1

r3(config-router)#network 4.0.0.0

r3(config-router)#network 5.0.0.0

r3(config-router)#exit

r3(config)#do write

Building configuration...

[OK]

r3(config)#

 

Step 5: Redistribute RIP Routes in to EIGRP on R2

r2(config)#router rip

r2(config-router)#redistribute eigrp 1 metric 1

r2(config-router)#

 

Step 6:Redistribute EIGRP Routes in to RIP on R2

r2(config)#router eigrp 1

r2(config-router)#redistribute rip metric 10000 1 255 1 1500

r2(config-router)#exit

r2(config)#do write

Building configuration...

[OK]

r2(config)#

 

Code Explanation: #redistribute rip metric  10000  1  255  1   1500

EIGRP was configured to redistribute all rip routes, and apply a metric of 10000 (bandwidth), 1 (delay), 255 (reliability), 1 (load), and 1500 (MTU) to the redistributed routes.

Step 7:Check Routing table

 

On r3

r3#show ip route

D EX 1.0.0.0/8 [170/258816] via 4.0.0.1, 00:03:04, FastEthernet0/0

D EX 3.0.0.0/8 [170/258816] via 4.0.0.1, 00:03:04, FastEthernet0/0

C 4.0.0.0/8 is directly connected, FastEthernet0/0

C 5.0.0.0/8 is directly connected, FastEthernet0/1

on r2

r2#show ip route

R 1.0.0.0/8 [120/1] via 3.0.0.1, 00:00:22, FastEthernet0/0

C 3.0.0.0/8 is directly connected, FastEthernet0/0

C 4.0.0.0/8 is directly connected, FastEthernet0/1

D 5.0.0.0/8 [90/30720] via 4.0.0.2, 00:07:48, FastEthernet0/1

 

On r1:

r1#show ip route

C 1.0.0.0/8 is directly connected, FastEthernet0/0

C 3.0.0.0/8 is directly connected, FastEthernet0/1

R 4.0.0.0/8 [120/1] via 3.0.0.2, 00:00:12, FastEthernet0/1

R 5.0.0.0/8 [120/1] via 3.0.0.2, 00:00:12, FastEthernet0/1

 

Step 8:Check Connection using PING.

Test configuration from PC0

PC>ipconfig

FastEthernet0 Connection:(default port)

Link-local IPv6 Address.........: FE80::20A:41FF:FE75:7366

IP Address......................: 1.0.0.2

Subnet Mask.....................: 255.0.0.0

Default Gateway.................: 1.0.0.1



PC>ping 5.0.0.2

Pinging 5.0.0.2 with 32 bytes of data:

Reply from 5.0.0.2: bytes=32 time=0ms TTL=125

Reply from 5.0.0.2: bytes=32 time=0ms TTL=125

Reply from 5.0.0.2: bytes=32 time=0ms TTL=125

Reply from 5.0.0.2: bytes=32 time=1ms TTL=125

Ping statistics for 5.0.0.2:

Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),

Approximate round trip times in milli-seconds:

Minimum = 0ms, Maximum = 1ms, Average = 0ms
