3.3.i Implement, optimize and troubleshoot manual and auto summarization with any routing protocol

R8(config-router)#do sh ip int brie | b Loop
Loopback0                 YES manual up                    up
Loopback1              YES manual up                    up
Loopback2              YES manual up                    up
Loopback3              YES manual up                    up

use area range on the abr for inter-area…

R7(config)#router ospf 1
R7(config-router)#area 1 range

R6(config-router)#do sh ip route ospf is subnetted, 1 subnets
O IA [110/3] via, 00:09:40, FastEthernet1/0

3.4.a Implement and troubleshoot RIPv2

R8(config-router)#do sh run | sec rip
router rip
version 2
no auto-summary

R7#sh ip route rip is subnetted, 3 subnets
R [120/1] via, 00:00:18, FastEthernet0/0
R [120/1] via, 00:00:18, FastEthernet0/0
R [120/1] via, 00:00:18, FastEthernet0/0 is subnetted, 1 subnets
R [120/1] via, 00:00:18, FastEthernet0/0

R7#sh run | sec ospf
ip ospf authentication-key cisco
router ospf 1
 redistribute rip subnets
network area 0
redistribute ospf 1 metric 5

R5#sh ip route | i 172 is subnetted, 1 subnets
