IP Routing Features

Configuring Static IP Routes

Disabling ICMP Redirects

You can disable ICMP redirects on the HP routing switch. only on a global basis, for all the routing switch interfaces. To disable ICMP redirects globally, enter the following command at the global CONFIG level of the CLI:

HPswitch(config)# no ip icmp redirects

Syntax: [no] ip icmp redirects

Configuring Static IP Routes

The IP route table can receive routes from the following sources:

Directly-connected networks – When you add an IP VLAN interface, the routing switch automatically creates a route for the network the interface is in.

RIP – If RIP is enabled, the routing switch can learn about routes from the advertisements other RIP routers send to the routing switch. If the route has a lower administrative distance than any other routes from different sources to the same destination, the routing switch places the route in the IP route table.

OSPF – See RIP, but substitute “OSPF” for “RIP”.

Statically configured route – You can add routes directly to the route table. When you add a route to the IP route table, you are creating a static IP route. This section describes how to add static routes to the IP route table.

Default network route – This is a specific static route that the routing switch uses if other routes to the destination are not available. See “Configuring the Default Route” on page 16-19.

Static Route Types

You can configure the following types of static IP routes:

Standard – the static route consists of the destination network address and network mask, and the IP address of the next-hop gateway. You can configure multiple standard static routes with the same metric for load sharing or with different metrics to provide a primary route and backup routes.
