Objectives
Configure OSPF with authentication
Configure EIGRP
Configure default routing and propagate it using OSPF
Verify network connectivity
Preconfigs
Note: The ?no keepalive? command is added to FastEthernet0/0 interface. This will bring the interface up without having to connect a switch or a hub.
The following items have been pre-configured on these devices:
The topology cabling
Hostname on all routers
Interface IP address on the routers
Interface clock rate on the routers
Following are the actual commands already configured on the devices:
Router1
hostname Router1
interface FastEthernet0/0
ip address 172.16.2.33 255.255.255.224
no keepalive
no shutdown
interface Serial0/0
ip address 172.16.1.2 255.255.255.252
clockrate 56000
no shutdown
Router2
hostname Router2
interface FastEthernet0/0
ip address 172.30.1.1 255.255.255.0
no keepalive
no shutdown
interface Serial0/0
ip address 172.16.1.1 255.255.255.252
no shutdown
interface serial0/1
ip address 10.10.1.1 255.255.255.252
clockrate 56000
no shutdown
Router3
hostname Router3
interface FastEthernet0/0
ip address 172.30.2.1 255.255.255.0
no keepalive
no shutdown
interface serial0/1
ip address 10.10.1.2 255.255.255.252
no shutdown
Configuration Tasks
Configure OSPF with Authentication
Configure OSPF routing between Router1 and Router2 with the process ID of 50.
Configure OSPF so only the following 172.16.0.0 subnets will be routed.
172.16.2.32/27
172.16.1.0/30
Configure Router1 with the OSPF router ID of 192.168.1.1.
Configure Router2 with the OSPF router ID of 192.168.1.2.
Configure the OSPF hello interval to 5 seconds and the OSPF dead interval to 20 seconds.
Configure the OSPF communication between the routers to use authentication with MD5 encryption.
Configure EIGRP
Configure EIGRP between Router2 and Router3 with an AS of 100.
EIGRP should only route for the following networks.
10.10.1.0/30
172.30.1.0/24
172.30.2.0/24
Configure Default Routing and propagate it using OSPF
On Router 2, configure a default static route to Router 3.
Propagate that default route to all routers in the OSPF routing domain.
Verify connectivity
Router2 should be able to ping all interfaces on all routers. Router1 and Router3 will not be able to ping all interfaces since there is no redistribution between OSPF and EIGRP in this scenario. Router1 should be able to ping all OSPF-enabled interfaces and Router3 should be able to ping all EIGRP-enabled interfaces.

Hi ,
Following is the config....
Experts ,
If any mistake is there in config plz correct me...
Configure OSPF so only the following 172.16.0.0 subnets will be routed.
172.16.2.32/27
172.16.1.0/30
Router1:
Router ospf 50
Network 172.16.2.32 0.0.0.31 area 0
Network 172.16.1.2 0.0.0.0 area 0
reditribute static
ip route 172.30.1.0 255.255.255.0 172.16.1.2
ip route 10.10.1.0 255.255.255.252 172.16.1.2
Router2:
Router ospf 50
Network 172.16.1.1 0.0.0.0 area 0
default-information originate always
Ip route 0.0.0.0 0.0.0.0 10.10.1.2
Configure Router1 with the OSPF router ID of 192.168.1.1.
Config)# router-id 192.168.1.1
Configure Router2 with the OSPF router ID of 192.168.1.2.
Config)# router-id 192.168.1.12
Configure the OSPF hello interval to 5 seconds and the OSPF dead interval to 20 seconds.
Router1:
interface Serial0/0
ip ospf hello-interval 5
ip ospf dead-interval 20
Router2:
inter interface Serial0/0
ip ospf hello-interval 5
ip ospf dead-interval 20
Configure the OSPF communication between the routers to use authentication with MD5 encryption.
Router1:
interface Serial0/0
ip ospf message-digest-key 100 md5 OLD
Router2:
interface Serial0/0
ip ospf message-digest-key 100 md5 OLD
Configure EIGRP
Configure EIGRP between Router2 and Router3 with an AS of 100.
EIGRP should only route for the following networks.
10.10.1.0/30
172.30.1.0/24
172.30.2.0/24
Router 2:
Router eigrp 100
Network 10.10.1.1 0.0.0.3
Network 172.30.1.0 0.0.0.255
Network 172.30.2.0 0.0.0.255.
No auto-summary
Router 3:
Router eigrp 100
Network 10.10.1.2 0.0.0.3
Network 172.30.2.0 0.0.0.255.
Redistribute static
No auto-summary
Ip route 172.30.1.0 255.255.255.0 10.10.1.2
Configure Default Routing and propagate it using OSPF
On Router 2, configure a default static route to Router 3.
Ip route 0.0.0.0 0.0.0.0 10.10.1.2
