Configuration example for RS-DCC with MP
Network requirements
As shown in Figure 51:
Two ISDN BRI interfaces on Router A and an ISDN PRI interface on Router B are connected across ISDN.
Interface Dialer0 on Router A is assigned an IP address 100.1.1.1/24, and interface Dialer0 on Router B is assigned an IP address 100.1.1.2/24.
Use RS-DCC on Router A to call Router B and C-DCC on Router B to call Router A. In addition, implement traffic distribution for the two interfaces on Router A by setting traffic thresholds and maximum bandwidth.

Configuration procedure
Configure Router A:
# Configure a dial access control rule for dialer access group 1. Create a local user account userb for Router B and configure PPP authentication for it, and set the traffic statistics collecting interval to 3 seconds for DCC.

# Assign an IP address to interface Dialer0, enable RS-DCC, and configure MP.

Configure Router B:
# Configure a dial access control rule for dialer access group 2. Create a local user account usera for Router A and configure PPP authentication for it, and set the traffic statistics collecting interval to 3 seconds for DCC.
<RouterB> system-view [RouterB] dialer-rule 2 ip permit [RouterB] local-user usera [RouterB-luser-usera] password simple usera [RouterB-luser-usera] service-type ppp [RouterB-luser-usera] quit [RouterB] dialer flow-interval 3
