Configuring multiple interfaces to receive calls from one or multiple remote ends
In Figure 45, multiple interfaces at the local end receive calls from 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 receive DCC calls from multiple remote interfaces including if1, if2, if3, and if4. Because multiple interfaces are involved at the local end, configure DCC parameters for them by configuring a dialer circular group. In addition, you can configure PAP or CHAP authentication.
To configure multiple interfaces to receive 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 interface to receive calls from a remote end. | dialer route protocol next-hop-address [ mask network-mask-length ] [ user hostname | broadcast ] * | Optional. If the dialer route ip next-hop-address user hostname command is configured at a called end, the called party will use the specified next hop address and hostname to authenticate the calling party. 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. |
