Included Routers

Device>Configure> Multi-Layer Switching>Included Routers

Catalyst 5000 series switches contain a Router Switch Module that automatically generates shortcut routes between LAN subnets for specified externally connected routers when such routers are included in (added to) the MLS-RP Included Routers window. You include a router in the shortcut process by entering its name and IP address in the Included MLS-RP table. You can add (or delete) up to 16 routers to (or from) the Catalyst 5000 Layer 3 shortcut process for participation in NetFlow. All added routers and Catalyst 5000 switches must be running NCP.


Note: All routers running FCP (Fusion Control Protocol) need not be specified here; the Catalyst 5000 series is designed to discover all such routers and automatically include them in the shortcut process. See the Shortcut Router Table feature for information about shortcut routers running FCP.
Router’s IP Address (cseRouterIndex)


IP address of the external router.

Router Name (cseStaticRouterName)

DNS name of the external router, if available. If there is no DNS name for the router, then this field will remain empty.

Click Add to enter the router’s IP address, then click Apply to make your entry take effect.

Click Delete to remove a router’s IP address from the table display.

Click Print to print the contents of the dialog box.

Click Cancel to close the dialog box.

Command Line Alternative: You can include an externally connected router in the Catalyst 5000 series shortcut process via the command line CLI/SNMP:

To add a router to the shortcut process, use: set mls include <router_ip | router_name>
To delete a router from the shortcut process, use: clear mls include <router_ip | router_name>.


Multi-Layer Switch - Route Processor

A Router Switch Module on each Catalyst 5000 series switch that automatically generates a shortcut process (as a subset of the LAN switch). The shortcuts filter and forward packets through a Catalyst 5000 switch based on the router’s MAC address, VLAN information, and network IP address, all received via NCP—a process that bypasses the externally-connected router altogether. No configuration is required.


Domain Name System

A system used in the Internet for translating names of network nodes into addresses.
