Cisco IOS Configuration

Note TPO ID in Cisco IOS should be same as the WCCP group ID in the NCE configuration.

Data Center Configuration

The following example shows the Cisco IOS configuration on the NCE router with two NCE service modules.

Configuration for Mask-based Load Balancing

Branch router configurations are similar to hash-based configurations.

For the Data Center router housing the NCE service modules, you must configure the concurrent routing and bridging (CRB) in Cisco IOS.
