NETGEAR 8800 User Manual
• VRRP VR on v1 with VRID of 99 with virtual IP addresses of 1.1.1.1 and 1.1.1.99 (one
virtual IP address is owned by the switch and one is not)
• VRRP VR on v1 with VRID of 100 with virtual IP addresses of 2.2.2.2 and 2.2.2.99 (one
virtual IP address is owned by the switch and one is not).
Configuring IPv4 Multinetting
You configure IP multinetting by adding a secondary IP address to a VLAN. Use the following
command to add a secondary IP address:
configure vlan <vlan_name> add secondary-ipaddress [<ipaddress> {<netmask>} |
<ipNetmask>]
After you have added a secondary IP address, you cannot change the primary IP address of
a VLAN until you first delete all the secondary IP addresses. To delete secondary IP
addresses, use the following command:
configure vlan <vlan_name> delete secondary-ipaddress [<ipaddress> | all]
IP Multinetting Examples
The following example configures a switch to have one multinetted segment (port 5:5) that
contains three subnets (192.168.34.0/24, 192.168.35.0/24, and 192.168.37.0/24).
configure default delete port 5:5
create vlan multinet
configure multinet ipaddress 192.168.34.1/24
configure multinet add secondary-ipaddress 192.168.35.1/24
configure multinet add secondary-ipaddress 192.168.37.1/24
configure multinet add port 5:5
enable ipforwarding
The following example configures a switch to have one multinetted segment (port 5:5) that
contains three subnets (192.168.34.0, 192.168.35.0, and 192.168.37.0). It also configures a
second multinetted segment consisting of two subnets (192.168.36.0 and 172.16.45.0). The
second multinetted segment spans three ports (1:8, 2:9, and 3:10). RIP is enabled on both
multinetted segments.
