	Router(config)#'''router ospf 456''' - Enables OSPF process. The number "456" is any positive number between 1 and 65, 535. It is not related to the OSPF area. The process ID is use to distinguish one process from another within the device. These numbers DO NOT have to match the process ID of an other router.		Router(config)#'''router ospf 456''' - Enables OSPF process. The number "456" is any positive number between 1 and 65, 535. It is not related to the OSPF area. The process ID is use to distinguish one process from another within the device. These numbers DO NOT have to match the process ID of an other router.

	~~_________________________________ STOPPED HERE FOR NOW _____________________________________________________~~		Router(config-router)#'''network''' ''172.10.0.0 0.0.0.255 area 0'' - OSPF advertises interfaces, not networks. It also uses the wildcard mask to determine whch interfaces to advertise. It is read as "any interface with the address of 172.10.0.0 is to be put in area 0.

	Router(config)#'''~~no router eigrp 100~~''' - ~~Removes EIGRP as a process.~~		Router(config-if)#'''ip address x.x.x.x x.x.x.x''' - Assigns IP address to interface

	Router(config-router)#'''~~network~~''' ~~''w.x.y.z~~'' - ~~''w~~.x.y.~~z'' is the directly connected network you want to advertise~~		Router(config-router)#'''router-id 10.1.1.1''''' - Sets ID to 10.1.1.1 Takes affect at next reload.

	Router(config-router)#'''no ~~network w~~.x.y.z''' - Removes ~~advertised network~~		Router(config-router)#'''no router-id 10..1.1.1''' - Removes the static router ID from the configuration. Takes affect at next reload.

	Router(config-~~router~~)#'''~~network 1.1.1.1 0.0.0.3~~''' - ~~Tells which~~ interface ~~or network~~ to ~~include~~ in ~~EIGRP~~. ~~Interfaces~~ are ~~configured with addresses that fall within~~ the ~~wildcard mask range of the network statement~~.		Router(config-if)#'''ip ospf priority 50''' - Changes the OSPF interface priority to 50. The assigned priority can be between 0 and 255. The higher the number the higher the priority. A 255 guarantees a tie in the election for DR/BDR. Ties are broken by the highest router ID.

	Router(config~~-router~~)#'''~~auto-summary~~''' - ~~Enables auto summarization for the EIGRP process~~		Router(config)#'''interface s0/0/0''' - Changes to interface config mode

	Router(config-~~router~~)#'''~~no auto-summary~~''' - ~~Turns~~ the ~~auto summarization feature~~ of ~~EIGRP off~~		Router(config-if)#'''bandwidth 128''' - If changed, OSPF will recalculate the cost of the link.

	** EIGRP automatically summarizes networks on the ~~classful boundary.~~		Router(config-if)#'''ip ospf hello-interval timer 20''' - Changes the hello interval to 20 seconds

	** If you have discontigous subnets you could have issues with connectivity if ~~summarization is left on.~~		Router(config-if)#'''ip ospf dead-interval 80''' - Changes the dead interval to 80 seconds

	** ~~If turned off, it is recommended~~ to ~~use the '''ip summary-address''' command to summarize manually.~~		** Hello and Dead Timers must match for routers to become neighbors

			Router(config)#'''ip route 0.0.0.0 0.0.0.0.0 s0/0''' - Creates a default route

			Router(config-router)#'''default-information originate''' - Sets the default route to be advertised to all OSPF routers

	Router~~(config)~~#~~'''~~interface ~~s0/0/0'''~~ - ~~Enters interface configuration mode~~		** You can verify configurations by running the show commands at the Router# prompt
			** Show ip protocol, show ip route, show ip ospf, show ip ospf interface, show ip ospf border-routers, show ip ospf neighbor
			** show ip ospf neighbor detail, show ip ospf database, show ip ospf database nssa-external

== Commands for RIP ==

Router(config)#'''router rip''' - Enables RIP as a protocol

Router(config-router)#'''network''' ''w.x.y.z'' - ''w.x.y.z'' is the directly connected network you want to advertise

Router(config)#'''no router rip''' - Turns off RIP

Router(config-router)#'''no network w.x.y.z''' - Removes network

Router(config-router)#'''version 2''' - Turns on V2 and now RIP will send and receive RIPv2 Packets

Router(config-router)#'''version 1''' - RIP will send and receive RIPv1 Packets

Router(config-router)#'''no auto-summary''' - RipV2 summarizes networks at the classful boundary. This command will turns auto summary off

Router(config-router)#'''passive-interface s/0/0/1''' - RIP updates will not be sent out this interface

Router(config-router)#'''neighbor a.b.c.d''' - Defines a specific neighbor to exchange information with

Router(config-router)#'''no ip split-horizon''' - Turns off split horizon (this is on by default)

Router(config-router)#'''ip split-horizon''' - Turns it back on

Router(config-router)#'''timers basic 30 60 90 180 270 360''' - Changes timers in RIP: 30=Update timer, 90=Invalid Timer, 180=Hold down timer, 270= Flush timer, 360=Sleep timer
