Configuration procedure

In this example, the ISDN PRIs on both Router A and Router B operate in user side mode (the default), and

the interfaces on the devices that connect to Router A and Router B in the ISDN network operate in

network side mode.

1. Configure Router A:

# Configure CE1/PRI interface 1/0 as an ISDN PRI into PRI group pri-set.

<RouterA> system-view

[RouterA] controller e1 1/0

[RouterA-E1 1/0] pri-set

[RouterA-E1 1/0] quit

# Create dialer access group 1 and configure a dial access rule to trigger calls for IP packets.

[RouterA] dialer-group 1 rule ip permit

# Assign ISDN PRI Serial 1/0:15 an IP address, enable C-DDR on the interface, dial 8810154 to

set up a link for packets destined to host address 202.38.154.2, and add the interface to dialer

access group 1.

[RouterA] interface serial 1/0:15

[RouterA-Serial1/0:15] ip address 202.38.154.1 255.255.0.0

[RouterA-Serial1/0:15] dialer circular enable

[RouterA-Serial1/0:15] dialer route ip 202.38.154.2 8810154

[RouterA-Serial1/0:15] dialer-group 1

2. Configure Router B:

# Configure CE1/PRI interface 1/0 as an ISDN PRI into PRI group pri-set.

<RouterB> system-view

[RouterB] controller e1 1/0

[RouterB-E1 1/0] pri-set

[RouterB-E1 1/0] quit

# Create dialer access group 1 and configure a dial access rule to trigger calls for IP packets.

[RouterB] dialer-group 1 rule ip permit

# Assign ISDN PRI Serial 1/0:15 an IP address, enable C-DDR on the interface, dial 8810152 to

set up a link for packets destined to host address 202.38.154.1, and add the interface to dialer

access group 1.

[RouterB] interface serial 1/0:15

[RouterB-Serial1/0:15] ip address 202.38.154.2 255.255.0.0
