Removing an Interface

You might want to remove an interface if you no longer need to communicate with IP on the ports associated with that interface.

Routes

To remove an IP interface definition:

1From the top level of the Administration Console, enter:

ip interface remove

2Enter the index numbers of the interfaces you want to remove.

Each system maintains a table of routes to other IP networks, subnets, and hosts. You can either make static entries in this table using the Administra- tion Console or configure the system to use RIP to automatically exchange routing information.

Each routing table entry contains the following information:

■Destination IP Address and Subnet Mask

These elements define the address of the destination network, subnet, or host. A route matches a given IP address if the bits in the IP address that corresponds to the bits set in the route subnet mask match the route destination address. When it forwards a packet, if the system finds more than one routing table entry matching an address (for example, a route to the destination network and a route to the specific subnet within that network), it will use the most specific route (that is, the route with the most bits set in its subnet mask).

■Routing Metric

This metric specifies the number of networks or subnets that a packet must pass through to reach its destination. This metric is included in RIP updates to allow routers to compare routing information received from different sources.
