# Configuring an ICR Partition

You can use RADIUS servers to authenticate subscribers and collect statistics related to the users logging in to an ICR partition on a virtual router. When you configure an ICR partition, you configure the interface on which the ICR partition resides and create a unique VRRP instance to manage the partition.

To configure an ICR partition:

1. Configure the interface.

   See Configuring the Interface on Which the ICR Partition Resides.

2. Create a unique VRRP instance to manage the ICR partition.

   See Configuring VRRP Instances to Match ICR Requirements.

3. Create and assign a name to the ICR partition.

   See Naming ICR Partitions.

4. (Optional) Select the grouping criterion for the ICR partition.

   See Grouping ICR Subscribers Based on S-VLAN IDs and Grouping ICR Subscribers Based on VLAN IDs.

   | Note: Grouping subscribers based on S-VLAN IDs is the default grouping option for ICR partitions. If you do not explicitly specify the grouping option, subscribers are grouped based on S-VLAN IDs.

5. (Optional) Configure RADIUS.

   See Using RADIUS to Manage Subscribers Logging In to ICR Partitions.
