  • Page 26: Network Connectivity Configuration

    Network connectivity configuration IRF is typically used with link aggregation to simplify the network topology. For high availability, set up multichassis link aggregations with the downstream switches and the upstream egress routers, as shown in Figure 11. The figure uses a single device to represents the four-chassis IRF fabric. A link aggregation could span one member device, some of the member devices, or all member devices, depending on the link redundancy requirements and number of available links.
