Cisco IOS Configuration

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

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.
