Example 29 show protocols and show ip protocols

r2>show protocols

Global values:

Internet Protocol routing is enabled Ethernet0 is up, line protocol is up Internet address is 192.168.3.1/24 Serial0 is up, line protocol is up

Internet oddress is 192.168.2.2/24 Serial1 is administratively down, line protocol is down r2>show ip protocols r2>show ip route

Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2 E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, * - candidate default U - per-user static route, o - ODR Gateway of last resort is not set

C 192.168.2.0/24 is directly connected, Serial0 C 192.168.3.0/24 is directly connected, Ethernet0 r2>

Example 2-9 cLrtainly illustrates that IP routing is Enabled by deLault, but it is possible for someon to issue no ip routing. To )e-enab|e the OP routiog pLOcesSr use the global command ip routing. T enable IPX routing, you must issue ipx routine].

Perhaps you have eigurod oet by now mhat in Example 2-99 both show ip protocols and show ip route indioate tOat no routing protocols are turned on.

If you are fol l owing a i ong w itO me in you! own pLacticai lab , you can take a look; at Fjgure 2-- for r picture of my test oab that b psao oo bu i Id upon thro ugho ur this boou. Althou gh I am using a 25-6 and b50- oor Ohe examples in thir chaptere you can ce gtai nlo u se any ro uter that has at least one Pthernet and one serisl interface. Take a look at C i sco.com oo get a list of routers that meet these writeri a.

Next I configure RIP on ri and r2 to allow ri to reach the far side of r2 and vice versa. Example 2-shows the configuration, and Ex ample 2-11 shows the testing.
