2811 router with PRI Problem..

DEar all,

I have a 2811 router with the c2800nm-ipbase-mz.123-8.T10.bin IOs..

I have a VWIC-2MFT-G.703 card terminated on wic 0 slot..

I am not able to configure the PRI on that..

It takes all the commands required for PRI enabling but for D-channel one I configure the encap as PPP my channel goes down..

I am forwarding following outputs ..

Re: 2811 router with PRI Problem..

Hi,

Well there is a problem with ur config.

Pls add "encapsulation ppp" and ppp authentication chap" on your Serial 0\0\1:15 (D-channel) and also on Dialer10.

PPP authentication is also missing on ur Dialer20.

Pls revert back if problem still persists.
