Can't ping across a PPP link

Dr_Atomic

I can't understand it - my serial interfaces are up/up between two routers, but I can't ping the IP address of the other router. It seems like a pretty simple configuration. They're almost identical.

Here's some of the output from Router 1:

username Alpha password Alpha

interface serial0
ip address 192.168.1.1 255.255.255.0
no ip directed-broadcast
clock rate 56000
bandwidth 1544
encapsulation ppp

Router 2:

username Omega password Alpha

interface serial0
ip address 192.168.2.1 255.255.255.0
no ip directed-broadcast
bandwidth 1544
encapsulation ppp

I'm on my phone so I can't see your configs, but your serial interfaces are on different networks. I would start looking there... Hth

he is right you should use the ip address 192.168.1.2 255.255.255.0 in the other side

Yeah, I finally figured out that I needed to put the routers on the same network. It worked fine, then. I figured that to have them ping while on different networks, I'd need a routing protocol - like RIP - so I configured it this way. I wasn't able to ping anymore. Still trying to figure out why not. Such a simple problem - I feel like a moron.....

Don't worry about it... everyone has made this mistake (okay... maybe not everyone, but I know I have).

Because the link between two interconnected devices must reside on the same network to communicate. Your routing protocols make communication possible between different networks.
