Configuring multiple interfaces to place calls to one or multiple remote ends
In , multiple interfaces at the local end place calls to one or multiple remote ends (the components in inverse color represent the routers irrelevant to the networking).

In this scenario, interfaces if0, if1, and if2 at the local end place DCC calls to interfaces if1, if2, and if3 at the remote ends. If only one remote end is involved, use the dialer number command to configure a dial string. If multiple remote ends are involved, you can use the dialer route command to configure the dial strings and destination addresses. As multiple interfaces are involved at the local end, configure DCC parameters for them by configuring dialer circular groups. In addition, you can configure PAP or CHAP authentication.
When placing calls, the physical interfaces in a dialer circular group use the IP address of the associated dialer interface instead of its own. An ISDN BRI or PRI interface itself can be regarded as a dialer circular group for its B channels. At the same time, it can be assigned to other dialer circular groups.
To configure multiple interfaces to place calls to one or multiple remote ends:
Step | Command | Remarks |
---|---|---|
1. Enter system view. | system-view | N/A |
2. Create a dialer interface and enter dialer interface view. | interface dialer number | N/A |
3. Enable C-DCC. | dialer enable-circular | By default, C-DCC is disabled. |
4. Configure the dial string and destination address for calling a remote end. | dialer route protocol next-hop-address [ mask network-mask-length ] [ user hostname | broadcast ] * dial-number [ autodial | interface interface-type interface-number ] * | If only one remote end is involved, you can use the dialer number dial-number command instead. Repeat this step if multiple remote ends are involved. |
5. Exit to system view. | quit | N/A |
6. Enter physical interface view. | interface interface-type interface-number | N/A |
7. Assign the physical interface to the dialer circular group corresponding to the dialer interface. | dialer circular-group number | The number argument in this command must take the same value assigned to the number argument in the interface dialer number command. |
8. Assign a priority to the physical interface in the dialer circular group. | dialer priority priority | Optional. The default priority is 1. |
