Routing 65
Software Release 2.4.1
C613-02021-00 REV B
To configure IP follow these steps
The following steps are required:
1. Configure the PPP Link.
2. Create a VLAN and add untagged ports.
3. Configure the IP routing module on both routers.
4. Test the configuration.
5. Save the configuration.
1. Configure the PPP Link
Refer to other sections of this guide on how to configure PPP interface 0 on
each router to use the wide area link.
•SeePoint to Point Protocol (PPP)” on page 49 for information about
configuring PPP to use a synchronous link.
•SeeConfiguring ISDN” on page 55 for information about configuring
PPP to use an ISDN call.
If the PPP interface is configured for dial-on-demand operation
(see“Configuring ISDN Dial on Demand” on page 60) or bandwidth on
demand operation (seeConfiguring ISDN Bandwidth on Demand” on
page 61), these services are automatically used by the IP routing
software.
2. Create VLANs and add untagged ports
Each new VLAN is created with a VLAN name that is unique in the router,
and a VLAN Identifier (VID) that uniquely identifies the VLAN on the
physical LAN. If the VLAN name begins with “vlan” and ends in a
number then the number must be the same as the VID specified. To create
VLANs, enter the command:
CREATE VLAN=vlanname VID=2..4094
In this example two VLANs are created by entering the commands:
CREATE VLAN=vlan2 VID=2
CREATE VLAN=vlan3 VID=3
To add untagged ports to vlan2, enter the command:
ADD VLAN=vlan2 PORT=2-7
To add untagged ports to vlan3, enter the command:
ADD VLAN=vlan3 PORT=1-3
See the Switching chapter in the AR400 Series Router Software Reference for
more detailed information about creating VLANs and VLAN ports.
3. Configure IP Routing
To clear any pre-existing IP configuration and turn on the IP routing
software on each router, enter the commands:
PURGE IP
ENABLE IP
On the Head Office router define two IP interfaces, one for the VLAN and
one for the wide area link:
ADD IP INT=VLAN2 IP=172.16.8.33 MASK=255.255.255.0
ADD IP INT=PPP0 IP=172.16.254.1 MASK=255.255.255.0
