Cisco 2610xm Can't Ping Serial Interfaces

Recommended Posts

Hi There,

 

I appear to be having problems with my CCNA lab when attempting to ping the serial interface on the router, thus not been able to connect to another router/network. When pinging ethernet interfaces, all works well.

 

For those of you who've seen my previous posts, the setup/topology is the same. (See attachment)

 

Any ideas as to what the problem/s may be?

 

 

Thanks in advance,

 

Rich

there are many possibilities... you should send a "sh ip int brie" & "sh run int serialx/x" output for both routers so we can help you

1] Check if both routers have same encapsulation PPP/HDLC

2] If ppp then check if authentication is sucessful and interfaces are up up.

3] Make sure your IP address are assigned correctly and you are pinging the right IPs.

as feelsicken said paste the output of the said commands if above mentioned doesnt work for you.

you should try the following :

 

on Router A :

conf t

ip route 192.168.3.0 255.255.255.0 192.168.2.2

 

on Router B :

conf t

ip route 192.168.1.0 255.255.255.0 192.168.2.1

 

 

or, if you prefer, on both routers :

 

router ospf 1

network 0.0.0.0 255.255.255.255 area 0

Ok guys, i've partly figured it out. Basically i still had my wireless router switched on. Once i i turned it off i could ping interfaces on both RouterA and RouterB from both computers.

 

Still unable to ping both end devices tho?

 

Any ideas with that?

 

Thanks

I guess your end devices still had their default gateway to the wireless interface

 

How is set you default-gateway on end devices ?

 

according to your design, host connected to routerA should have 192.168.3.1 & host to routerB should have 192.168.1.1

Previously you ask about this.. asking without complet topology is quite waste of time
