NICAST OUTING
The following rules apply when you are configuring IP multinetting:
• A maximum of one IP address is associated with a router interface (or VLAN).
• Multiple VLANs must be used to implement IP multinetting.
• A maximum of four subnets are allowed on one multinetted port.
• For multinetted segments that span multiple ports, you must configure all the
multinetted VLANs with the same port assignment.
• A maximum of one VLAN can run RIP or OSPF, and this VLAN must be configured
to use the IP protocol.
BOOTP works only on the VLAN assigned to the IP protocol.

ULTINETTING PERATION
To use IP multinetting, follow these steps:
1 Select a slot and port on which IP multinetting is to run.
For example, slot 1, port 2.
2 Remove the default VLAN from the selected port.
config default delete port 1:2
3 Create a dummy protocol.
create protocol mnet
4 Create the multinetted subnets.
create vlan net21
create vlan net22
5 Assign IP addresses to the net VLANs.
config net21 ipaddress 123.45.21.1 255.255.255.0
config net22 ipaddress 192.24.22.1 255.255.255.0
6 Assign one of the subnets to the IP protocol.
config net21 protocol ip
7 Assign the other subnets to the dummy protocol.
config net22 protocol mnet
