ip routing

Use this command to enable IP routing. Use the no form to disable IP routing.

Syntax

ip routing no ip routing

Default Setting

Enabled

Command Mode

Global Configuration

Command Usage

•The command affects both static and dynamic unicast routing.

•If IP routing is enabled, all IP packets are routed using either static routing or dynamic routing via RIP or OSPF, and other packets for all non-IP protocols (e.g., NetBuei, NetWare or AppleTalk) are switched based on MAC addresses. If IP routing is disabled, all packets are switched, with filtering and forwarding decisions based strictly on MAC addresses.

Example
