cisco Configuration
Hello,
Soon, I will need to setup a t1 line between 2 sites. I have purchased 2 Cisco 1841 routers with the T1 DSU/CSU card in slot 0 (WIC 1DSU-T1 V2).
Anyway, I think I have everything working properly back to back, but I'm running into a weird problem where one side (config A) can only ping the other side 60% of the time, and the other side (config B) can not ping config A at all. Below are my configurations. Can anybody tell me what I'm doing wrong? This is going to be my first T1 deployment, and it has to work. Thanks:
