On this post, I will be going through a short example of how this two routing domains were redistributed and will examine the routing information.

Below will be my topology for this laboratory,

Objective as follows:

a. Redistributed EIGRP networks into RIP with a RIP metrics of 5.

b. Redistributed RIP networks into EIGRP with a metrics as follows:
        BW = 1500, Delay = 100 , Reliability = 100, Load = 1 and MTU = 1500

c. Verify the reachability of networks between Manila and Melbourne.


Here are my router configurations:

Manila#sh run | sec eigrp
router eigrp 100
 network 0.0.0.0
Manila#

Singapore#sh run | sec rip
router rip
 version 2
 network 192.168.23.0
 no auto-summary

Singapore#sh run | sec eigrp
router eigrp 100
 network 192.168.12.0
Singapore#

Melbourne#sh run | sec rip
router rip
 version 2
 network 10.0.0.0
 no auto-summary
Melbourne#

We can simply check the routing table of Singapore for both EIGRP and RIP networks.

Singapore#show ip route  rip
!
Gateway of last resort is not set

      10.0.0.0/32 is subnetted, 5 subnets
D        10.10.10.1 [90/2297856] via 192.168.12.1, 00:11:21, Serial3/0
D        10.10.20.2 [90/2297856] via 192.168.12.1, 00:11:21, Serial3/0
Singapore#


Let’s redistributed the EIGRP into RIP from Singapore router.

Singapore(config)#router rip
Singapore(config-router)#redistribute eigrp 100
Singapore(config-router)#default-metric 5

Now, let check whether the EIGRP routes were injected into RIP domain.

Melbourne#show ip route rip

      10.0.0.0/32 is subnetted, 4 subnets
R        10.10.10.1 [120/5] via 192.168.23.2, 00:00:05, Serial3/1
R        10.10.20.2 [120/5] via 192.168.23.2, 00:00:05, Serial3/1
R     192.168.12.0/24 [120/5] via 192.168.23.2, 00:00:05, Serial3/1
Melbourne#


>> As Observed, I have now the EIGRP routes redistributed into RIP routing details with a metric of 5 as I have manually setup and with an AD of 120 (Default AD for RIP).

Let’s redistributed into EIGRP the RIP Routing information on Singapore router.

Singapore#config t
Enter configuration commands, one per line.  End with CNTL/Z.
Singapore(config)#router eigrp 100
Singapore(config-router)#redistribute rip
Singapore(config-router)#default-metric 1500 100 255 1 1500
Singapore(config-router)#^Z


Now, let’s check Manila router. It has the three networks from the EIGRP routing domains.

Manila#show ip route eigrp
!
Gateway of last resort is not set

      10.0.0.0/32 is subnetted, 4 subnets
D EX     10.10.30.3 [170/2244096] via 192.168.12.2, 00:00:12, Serial3/0
D EX     10.10.40.4 [170/2244096] via 192.168.12.2, 00:00:12, Serial3/0
D EX  192.168.23.0/24 [170/2244096] via 192.168.12.2, 00:00:12, Serial3/0
Manila#

>>>Again, since the routes were imported from other routing domains, it shows as External EIGRP with an AD of 170.

Now, checking the connectivity,

Manila#ping 10.10.30.3 source 10.10.10.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.10.30.3, timeout is 2 seconds:
Packet sent with a source address of 10.10.10.1
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 52/199/712 ms
Manila#ping 10.10.40.4 source 10.10.10.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.10.40.4, timeout is 2 seconds:
Packet sent with a source address of 10.10.10.1
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 52/78/112 ms
