Configuring host routes

Configure host routes when the switch resides in a network that uses routing protocols other than OSPF. A host route is a more-specific route and is used even if it is higher cost than a network route.

Before you begin

  • Enable OSPF globally.

  • Change the VRF instance as required to configure OSPF on a specific VRF instance. The VRF must have an RP trigger of OSPF. Not all parameters are configurable on non-default VRFs.

About this task

You can specify which hosts directly connect to the router and the metrics and types of service to advertise for the hosts.

Use a host route to create a custom route to a specific host to control network traffic.
