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 Serial0 is up, line protocol is up

Internet oddress is 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 is directly connected, Serial0 C 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.
