1.6.9 B Channels for Dial-up and Connection to the Remote End - Case 2

Case 2: DDR in which one B channel in ISDN BRI interface is used for dial connection to the remote end and the other for dedicated connection to the remote end.

Using one of the B channels of ISDN BRI interface for dial-up, the other one for remote dial-up connection.

I. Networking requirements

DDR is the implementation solution. As shown in the following diagram, router A can dial-up and dial to router B at the same time. We assume user access Internet with 163 Special Service number (user name: user163, password: pass163).

III. Configuration procedure

Solution: use Dialer Profile to realize:

1)Configure router A: Quidway(config)# access-list 1 deny any

Quidway(config)# access-list 1 permit 10.110.10.0 0.0.0.255

Quidway(config)# nat pool 202.110.10.10 202.110.10.11 pool 1

Quidway(config)# dialer-list 1 protocol ip permit
