Encapsulation failed error message on 1721 isdn

Level 1

Folks,

I'm testing an isdn simulator, arca technologies emutel solo, with 2 bri channels.

My problem is that while the siimulator tells me it can see layer 2 & 3 messages but when try to ping from RouterA, 10.1.1.1, to RouterB, 10.1.1.2, i get encapsulation failed error messages

I've copied in the configs for anyone who wants to have a look though i appreciate i may be asking a bit much!

I have 2 1721s with isdn and fastethernet interfaces

Many thanks to anyone who takes the time.

Hello,

it looks like you are uisng different passwords for your RouterA and RouterB:

username RouterA password 0 RouterA

username RouterB password 0 RouterB

Try to make them the same and see if it works.

Regards,

Georg
