CCNA - ICND question - help

I need help on a question from the CCNA-ICND test.

I didn't pass for a second time, and got the exact same score of

837/1000. 849 is a pass.

I believe this problem is what I've been getting wrong:

2 things needed:

- correct addressing on RtrA

- correct LAN config on RtrB

Server & Host Y need to be able to communicate.

Connections: Host consoled to RtrA

RtrA s0/0 connected to RtrB s0/0 RtrA fa0/0 connected to Sw1

Sw1 connected to Server 10.1.1.148/24

RtrB fa0/0 connected to Sw2

Sw2 connected to Host Y 192.168.3.28/24

Config's:

RtrA: s0/0

192.168.2.5/30

fa0/0

10.1.1.147/24

rip 10.0.0.0 rip 192.168.2.0

RtrB:

192.168.2.6/30

fa0/0

192.168.3.27/24 shut

rip 192.168.2.0 rip 192.168.3.0

Of course I enable RtrB fa0/0, which is half of the answer. I can't figure out any problems with the addressing on RtrA.

Can someone help me? I'd really appreciate it. Thanks

Thanks Klutz, but would you mind explaining why you'd change the serial int's from:

192.168.2.5/30 192.168.2.6/30 to 192.168.10.5/24 192.168.10.6/24 ... ?

I understand RIPv1 is classful, but isn't subnetting to /30 allowed ? This isn't VLSM, correct?

I know it isn't VLSM, but RIP version1 don't announce the subnet mask. So,on RTA,192.168.2.5/30 and 192.168.2.0/24 are in the same network .Router's interface should connect different network. You announce the network 192.168.2.0 on fa0/0 of RTA,how it determine the packet's export? s0/0 or fa0/0?

OK, sorry just realized I still had my home lab available -- too much studying without it I guess.

I punched the config in and the addressing works fine.

So when the Sim asks to fix/correct the addressing on RtrA, what else could that entail? Anyone have any ideas?

Has anyone taken the ICND recently? Thanks again

Where are you seeing that? The original config is this (rewritten in IOS format):

RtrA

int s0/0 ip address 192.168.2.5 255.255.255.252

int fa0/0 ip address 10.1.1.147 255.255.255.0

router rip network 10.0.0.0 network 192.168.2.0

RtrB

int s0/0 ip address 192.168.2.6 255.255.255.252

int fa0/0 ip address 192.168.3.27 255.255.255.0 shutdown

router rip network 192.168.2.0 network 192.168.3.0

Server (10.1.1.148/24) connected to RtrA's LAN Host Y (192.168.3.28/24) connected to RtrB's LAN

So, other than doing "no shutdown" on RtrB's fa0/0 and adding "version 2" to both rip configs, I don't see what else can be wrong here.

How do you know you didn't get this one right?

Did you ping to test? All I could see was whether or not you ensured rip was at v2 or used another routing protocol, as it wouldn't work with v1.

During the Sim, I was able to ping both the Server and HostY from both routers. At home, I only used Ripv1, so addressing seems to work as is.

I know I got it wrong because the Sim asked for 2 things and I could only do 1.

HEY!

that's strange, i already replied to this yesterday.

anyway, i too put this into my home lab (sorry, i forgot i had it -- too much studying). the addressing for rip v1 works as is.

so, now i don't know what the sim wants when it says to correct the addressing on rtr a. it's supposed to be straight-forward, but this one isn't.

anyone take the icnd recently?
