Indledning

Denne opgave giver et indblik i fejlfinding af RIP og konvergerings tiderne for RIP.


Opgave

Netværket skal være konfigureret som i Configuration af netværk med RIP og i skal kunne se alle de andre gruppers netværk med show ip route kommandoen. Som vist her: 

Router#<input>show ip route</input>
Codes: L - local, C - connected, S - static, R - RIP, M - mobile, B - BGP

C     192.168.10.0/24 is directly connected, FastEthernet0/0
<notice>R     192.168.33.0/24 [120/1] via 192.168.10.20, 00:00:19, FastEthernet0/0
R     192.168.36.0/24 [120/1] via 192.168.10.50, 00:00:13, FastEthernet0/0
R     192.168.37.0/24 [120/1] via 192.168.10.60, 00:00:08, FastEthernet0/0
R     192.168.38.0/24 [120/1] via 192.168.10.70, 00:00:14, FastEthernet0/0
R     192.168.39.0/24 [120/1] via 192.168.10.80, 00:00:13, FastEthernet0/0</notice>
C     192.168.146.0/24 is directly connected, FastEthernet0/1

Hvor mange netværk fortæller jeres Router om?

Hvilke naboer modtager den information fra?

Opgave 2

I skal nu prøve at se hvor lang tid der går fra i fjerner et netværk til jeres naboer opdager det.
2 hold går sammen og det enehold trækker kabler ud, mens det andet hold tager tid indtil netværket fjernes fra Routing tabellen.

  • Det ene hold starter med at trække kablet på LAN siden af deres Router.

Hvor lang tid går der før netværket forsvinder fra den anden Router?

Sæt nu kablet i igen, og vent til netværket kommer op igen.

  • Det ene hold trækker nu WAN forbindelsen på deres router.

Hvor lang tid går der før netværket forsvinder nu?
