Routing Protocols

(EIGRP Configuration) 

Objective

Understanding the Routing Updates using the Dynamic Routing Protocol (EIGRP).

Diagram

Procedure

1. Configuring & Assigning the IP addresses on the routers R1 & R2.
2. Check the routing table on both the routers.
3. Enable the EIGRP protocol on both routers so that hosts on the both routers can communicate with each other.
4. Verifying the Routing protocols on the Router.
5. Check the routing table on both the routers after enabling the EIGRP on both sides.
6. Verifying the connection of both hosts.

Configuration         

Step 1(A): Assigning the IP addresses on the Router R1.

R1(config)#interface serial 0

R1(config-if)#ip address 15.0.0.1 255.0.0.0

R1(config-if)#no shutdown

R1(config-if)#clock rate 64000   (Clock Rate will set only DCE Interface)

R1(config-if)#exit

R1(config)#interface ethernet 0

R1(config-if)#ip address 10.0.0.20 255.0.0.0

R1(config-if)#no shutdown

R1(config-if)#end

Step 1(B): Assigning the IP addresses on the Router R2.

R2(config)#interface serial 0

R2(config-if)#ip address 15.0.0.2 255.0.0.0

R2(config-if)#no shutdown

R2(config-if)#end

R2(config)#interface ethernet 0

R2(config-if)#ip address 20.0.0.2 255.0.0.0

R2(config-if)#no shutdown

R2(config-if)#exit

Step 2(A): Check the Routing table of the Router R1.

RA#sh ip route

C    10.0.0.0/8 is directly connected, Ethernet0

C    15.0.0.0/8 is directly connected, Serial0

Step 2(B): Check the Routing table of the Router R2.

RB#sh ip route

C    20.0.0.0/8 is directly connected, Ethernet0

C    15.0.0.0/8 is directly connected, Serial0

Step 3(A): Enable the EIGRP protocol on the Router R1.

RA(config)#router eigrp 10

RA(config-router)#network 10.0.0.0 (Networks to be advertised)

RA(config-router)#network 15.0.0.0 (Networks to be advertised) 

Step 3(B): Enable the EIGRP protocol on the Router R2.

RB(config)#router eigrp 10

RB(config-router)#network 20.0.0.0 (Networks to be advertised)

RB(config-router)#network 15.0.0.0 (Networks to be advertised) 

Step 4(A): Check the Routing Protocol on the Router R1.

RA#show ip protocols

Routing Protocol is "eigrp 10"

  EIGRP metric weight K1=1, K2=0, K3=1, K4=0, K5=0

  EIGRP maximum hopcount 100

  EIGRP maximum metric variance 1

  Redistributing: eigrp 10

  Automatic network summarization is in effect

  Automatic address summarization:

    15.0.0.0/8 for Ethernet0

  Routing for Networks:

    10.0.0.0

    15.0.0.0

  Routing Information Sources:

    Gateway         Distance      Last Update

    15.0.0.2              90      00:01:06

  Distance: internal 90 external 170

Step 4(B): Check the Routing Protocol on the Router R2.

RB#show ip protocols

Routing Protocol is "eigrp 10"

  EIGRP metric weight K1=1, K2=0, K3=1, K4=0, K5=0

  EIGRP maximum hopcount 100

  EIGRP maximum metric variance 1

  Redistributing: eigrp 10

  Automatic network summarization is in effect

  Automatic address summarization:

    15.0.0.0/8 for Ethernet0

    20.0.0.0/8 for Serial0

  Routing for Networks:

    15.0.0.0

    20.0.0.0

  Routing Information Sources:

    Gateway         Distance      Last Update

    15.0.0.1              90      00:02:47

  Distance: internal 90 external 170

Step 5(A): Check the Routing table of the Router R2 after enabling EIGRP.

RA#sh ip route

D    20.0.0.0/8 [90/2195456] via 15.0.0.2, 00:04:42, Serial0

C    10.0.0.0/8 is directly connected, Ethernet0

C    15.0.0.0/8 is directly connected, Serial0

Step 5(B): Check the Routing table of the Router R2 after enabling EIGRP.

RB#sh ip route

C    20.0.0.0/8 is directly connected, Ethernet0

D    20.0.0.0/8 [90/2195456] via 15.0.0.1, 00:01:12, Serial0

C    15.0.0.0/8 is directly connected, Serial0

Step 6: Verifying the connection of Host ‘A’ & Host ‘B’.

C:\>ping 20.0.0.1

Pinging 20.0.0.1 with 32 bytes of data:

Reply from 20.0.0.1: bytes=32 time=20ms TTL=254

Reply from 20.0.0.1: bytes=32 time=20ms TTL=254

Reply from 20.0.0.1: bytes=32 time=10ms TTL=254

Reply from 20.0.0.1: bytes=32 time=10ms TTL=254

Ping statistics for 20.0.0.1:

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

Approximate round trip times in milli-seconds:

    Minimum = 10ms, Maximum =  20ms, Average =  15ms
