18An Introduction to IP Routing Protocols

Network with Multinetting

You can configure a static route with the next hop on the secondary interface. You can also add static ARP for a given IP address in the same subnet of a secondary interface.

Here are some limitations when you are working with secondary interfaces:

•you can have a maximum of eight secondary interfaces on each VLAN

•you can have a total maximum of 256 IP interfaces (including primary and secondary)

•all of the secondary interfaces on a VLAN are enabled or disabled together. There is no provision for configuring the administrative state of the secondary IP interfaces individually.

•dynamic routing is not available for secondary IP interfaces

•secondary interfaces are not supported on brouters

•a primary IP interface must be in place before secondary IP interfaces can be added; secondary interfaces must be deleted before you can delete the primary
