IP U NICAST R 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, and this VLAN must be configured to use
the IP protocol.
BOOTP works only on the VLAN assigned to the IP protocol.
IP M ULTINETTING O PERATION
To use IP multinetting, follow these steps:
1 Select a port on which IP multinetting is to run.
For example, port 2.
2 Remove the default VLAN from the selected port.
config default delete port 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
