Case Projects

Case Project 1RIP will only work until Big Tin adds more routers. This is because RIP updates can only traverse 15routers and their autonomous system already includes 14 routers.

Case Project 2ogan!s could use I"RP as their Interior "ateway Routing protocol. #onsiderable $%& bandwidth isstill used 'or updates however( I"RP only broadcasts every )* seconds instead o' +* like RIP.Bandwidth and delay are the two metrics in use by de'ault when I"RP is con'igured. ogan!s may alsowant to con'igure I"RP to use hops. ,uggest that ogan!s sets the ma-imum number o' hops to the

number o' routers in the autonomous system. I"RP can support up to 55 hops.

Case Project 3The router rip command is con'igured at the global con'iguration mode prompt. In this case that promptwould appear as newyork/con'ig0. 2nce the router rip command is entered3 the prompt will change tonewyork/con'igrouter0. enni'er is unnecessarily con'iguring three network commands instead o' theone re6uired. 2nly the ma7or network number should be con'igured( subnet numbers /or inter'aceaddresses0 should not be con'igured. The one network command should be network 204.207.5.0. I' it iscon'igured with three commands as enni'er suggests3 the router will simply combine the commandsand con'igure 'or the ma7or network number only. In other words3 it will work3 but enni'er will get itwrong on the ##&% e-am.
