Router(config-if)#cdp enable →Enables CDP on Interface
Router#show cdp traffic
Router#clear cdp counters
Router#show cdpRouter#show cdp entry {*|device-name [*][protocol | version]}
Router#show cdp interface [type number]
Router#show cdp neighbors [type number] [detail]

• Configuring Static Routes

Router(config)#ip route
Router(config)#ip route
Router(config)#ip default-network

• Configuring RIP v1

Router(config)#router rip
Router(config-router)#network
Router(config-router)#passive interface→Avoid Sending Updates
Router(config-router)#neighbor →Defines a neighbor router
Router(config-router)#redistribute static →Propagates static routes also
Router(config-router)#timers basic
Router(config-router)#default-information originate →Sends RIP neighbors default gateway

→RIP v1 Verification

Router#debug ip rip
Router#show ip rip database

• Configuring IGRPRouter(config)#router igrp
Router(config-router)#network

→IGRP Verification

Router#debug ip igrp events
Router#debug ip igrp transactions

• Configuring ACLs

→Standard ACLs

Router(config)#access-list
Router(config-if)#ip access-group

→Extended ACLs

Router(config)#access-list

Router(config-if)#ip access-group

• Configuring RIP v2Router(config)#router rip

Router(config-router)#network

• Configuring OSPF

Router(config)#router ospf
Router(config-router)#network area

→OSPF Priority

Router(config)#interface
Router(config-if)#ip ospf priority →DR Highest Priority
Router#show ip ospf interface

Router(config-router)#area authentication

→OSPF Authentication with Encryption

Router(config-if)#ip ospf message-digest-key md5

Router(config-router)#area authentication message-digest

→OSPF Timers

Router(config-if)#ip ospf hello-intervalRouter(config-if)#ip ospf dead-interval →Dead=4*Hello

→Default Route Propagation through OSPF

Router(config)#ip route 0.0.0.0 0.0.0.0
Router(config-router)#default-information originate

→OSPF Verification

Router#show ip ospf interface
Router#show ip ospf
Router#show ip ospf neighbor
