To do...
Assign a priority to the
physical interface in the dialer
circular group
Configuring multiple interfaces to receive calls from one or multiple
remote ends
As shown in the following figure, 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):

remote ends
if0
Local end
if1
(Multiple
interfaces)
if2
In this scenario, interfaces if0, if1, and if2 at the local end receive DCC calls from
multiple remote interfaces including if1, if2 and if4. As multiple interfaces are
involved at the local end, configure DCC parameters for them by configuring a
dialer circular group. In addition, you may configure PAP or CHAP authentication.
After completing the basic DCC configurations, follow these steps to configure
multiple interfaces to receive calls to one or multiple remote ends:
To do...
Enter system view
Create and enter dialer
interface view
Enable C-DCC
Configure the interface to
receive calls from a remote
end (if multiple remote ends
are involved, repeat this step)
Exit to system view
Enter physical interface view
Use the command...
dialer priority priority
Remote end A
(Single/Multiple
if1 interfaces)
if2
Remote end B
(Single/Multiple
interfaces)
if3
Remote end C
if4
(Single/Multiple
interfaces)
Use the command...
system-view
interface dialer number
dialer enable-circular
dialer route protocol
next-hop-address [ mask
network-mask-length ] [ user
hostname | broadcast ] *
quit
interface interface-type
interface-number

Remarks
Optional
The default priority is 1.
Remarks

--
Required
Disabled by default.
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.
