Can't ping s0 from ethernet side

I cannot ping the s0 from the ether side of the network. Here is the sh run. Thanks for any suggestions.

you have no keep set on the s0 , is the line down ? is your CD lead high ?

put the command keep 10 on s0 see if the line goes up

[dpropson]

Interface IP-Address OK? Method Status Prot

ocol

FastEthernet0 10.1.1.37 YES manual up up

Serial0 192.168.100.1 YES NVRAM up up

Is this what you are referring to?

Thank you for your help.

[dpropson]

I did set keepalive on s0 to 10 and still cannot ping the s0. Thanks.

[deilert]

can you paste in a sh int s0 and a sh ip route

[deilert]

no when you disable keepalives , by using the no keepalives command this is what you have done on s0 , the interface will always show up up , you should look at the CD controll lead to determine if the line is up , see below the 'DCD=up' means that the line is up. Does your interface show DCD=up or DCD=down ?

Hey guys,

I set the keepalives to 10, tested it and it still wouldn't work, set it back to no and now it is fine.

One other thing, if you don't mind. I can now ping from the 192.168 network, s0 side and e0 side but not an address on the 10.1.1.0. Any ideas why?

Dennis

[deilert]

can you paste in a sh ip route .

what is the source address and destination address of your ping

[dpropson]

deilert,

It goes something like this:

From 192.168.132.2(PC) ping 192.168.132.42 (e0) successful..ping 192.168.100.2 (s0) successful..ping 192.168.100.1 (s0) successful..ping 10.1.1.37 (e0) successful..ping 10.1.1.1-254 (PCs on 10.) unsuccessful.

thanks.

[deilert]

the subnet mask you are using on your FE is 8 bits , are you using this on the hosts machines ? If you are the pings will not even hit the router they will stay loacl on the segment and will be found by arp requests

[dpropson]

Deilert,

I did change the subnet to 10.1.1.0 255.255.255.0. I am still not having any luck. I can ping while on a router, but not from the network side to the s0 side once again. I did a sh int s0 dcd (and everything else) is up. Suggestions?

You did not give the config of the router at the other end of the link. This could be useful. Try removing the redistribute connected though. Guess it is confusing the RIP. What are you using at the other end, RIP or static, check for missing routes i.e if RIP, that all necessary interfaces are specified, for static, all routes are defined.

[deilert]

Where is the subnet 10.1.1.1-254 located ? does it hang off the FE with the 10.1.1.37 255.0.0.0 ? Are there any other routers between ?

Can you past in a sh ip route from this router ?
