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).
Figure 45 Multiple interfaces receive calls from one or multiple remote ends
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.
