Grouping ICR Subscribers Based on VLAN IDs
Copyright © 2010, Juniper Networks, Inc.
The default grouping option is S-VLAN. If you do not explicitly specify the grouping
option, the subscribers are grouped based on S-VLAN.
Add S-VLAN subinterfaces to the ICR partition by doing either of the following:
2.
Specify the S-VLAN IDs individually by using the svlan-list keyword. In the following
example, you add individual S-VLAN subinterfaces by specifying each S-VLAN ID.
host1(config-if)#ip vrrp 1 icr-partition svlan-list 100 102 105 108 114 125
control-interface advertise-mac
Specify the starting ID and ending ID of the range of S-VLAN subinterfaces. In the
following example, you specify the first and the last ID of the range because the IDs
are in sequential order.
host1(config-if)#ip vrrp 1 icr-partition svlan-range 100 110 control-interface
advertise-mac
(Optional) Add an S-VLAN and VLAN subinterface pair to the ICR partition.
3.
host1(config-if)#ip vrrp 1 icr-partition svlan-list-explicit 120 1 120 2 control-interface
advertise-mac
NOTE: To enable the new master router to send PPPoE Active Discovery
Termination (PADT) packets to the clients and create new sessions for
the PPPoE subscribers, you must create a dummy IP interface for each
S-VLAN that is part of the ICR partition.
(Optional) Configure additional S-VLAN subinterfaces by completing Steps 2 and 3
4.
using unique numbering.

You can configure ICR subscribers based on VLAN IDs. When you configure a VLAN list
or VLAN range, you can include any or all of the following keywords:
Use the control-interface keyword to control the state of the corresponding
subinterfaces (up/AdminDown) based on the state of the partition (master or backup).
If the subinterfaces are part of the backup partition, the router changes the state of all
the subinterfaces to AdminDown.
