ISDN BRI conf. 4 multiple remote access

[scolombo]

I'd like to know how can I configure the BRI interface of a 3640 to allow simultaneous access from remote branch offices.

I have set up the config as follow

!

interface BRI0/0

no ip address

encapsulation ppp

no ip route-cache

no ip mroute-cache

dialer pool-member 1

dialer pool-member 2

isdn switch-type basic-net3

no cdp enable

ppp multilink

!

interface Dialer1

description AMS

ip address 10.221.1.1 255.255.255.252

encapsulation ppp

no ip route-cache

no ip mroute-cache

dialer pool 1

dialer remote-name AMS

dialer idle-timeout 300

dialer string yyyyyyyyyyyyyyyyy

dialer-group 1

no cdp enable

ppp callback request

ppp authentication chap

ppp multilink

!

interface Dialer2

description CMC

ip address 10.221.1.5 255.255.255.252

encapsulation ppp

no ip route-cache

no ip mroute-cache

dialer pool 2

dialer remote-name CMC

dialer string xxxxxxxxxxxxxxxxxx

dialer-group 2

no cdp enable

ppp authentication chap

but it doesn't work.

If I remve one of the dialer pool-member line from the bri interf. at least one of the branch can connect

TIA

Here is the link which discuss that the same what you want to do..

http://www.cisco.com/warp/public/793/access_dial/ddr_dialer_profile.html

We need to debug about why the second branch can't connect..

Above link has a debug information..Pl. post

debug isdn q931

debug ppp authentication

debug ppp negotiation..

Thx..Tejal

When I put both of the dialer pool-member line int the HUB configuration none of the remote branches connect.

I've already enabled the debug and found an "unbindable" error.

[tepatel]

"unbindable" means the dialer interface/profile is not found for the the dialin user. Just turn on the authentication (just add "ppp authentication chap") under the interface bri0/0 so that dialin users will be bind to the interface based on the username presented during the authentication phase.

Pl. check the username which is presented by the remote branches. Make sure that you have "dialer remote-name xxx" configured under the dialer interface where xxx (case sensitive) exactly matches the usersname presented by dialin user. With that things should work..Thx..Tejal
