18 An 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
