3Com Switch 8800 Configuration Guide Chapter 41 VRRP Configuration
41-4
Due to the chips installed, some switches support matching one IP address to multiple
MAC addresses.
The Switch 8800 not only guarantees correct data forwarding in the sub-net, but also
support such function: the user can choose to match the virtual IP address with the real
MAC address or virtual MAC address of the routing interface.
The following commands can be used to set correspondence between the IP address
and the MAC address.
Perform the following configuration in system view.
Table 41-3 Set correspondence between virtual IP address and MAC address
Operation Command
Set correspondence between the virtual
IP address and the MAC address vrrp method { real-mac | virtual-mac }
Set the correspondence to the default
value undo vrrp method
By default, the virtual IP address of the virtual router corresponds to the virtual MAC
address.
You should set correspondence between the virtual IP address of the virtual router and
the MAC address before configuring the virtual router. Otherwise, you cannot configure
the correspondence.
If you set correspondence between the IP address of the virtual router and the real
MAC address, you can configure only one virtual router on VLAN interface.
41.2.4 Adding/Deleting a Virtual IP Address The following command is used for assigning a virtual IP address of the local segment
to a virtual router or removing an assigned virtual IP address of a virtual router from the
virtual address list.
Perform the following configuration in VLAN interface view.
Table 41-4 Add/delete a virtual IP address
Operation Command
Add a virtual IP address vrrp vrid virtual-router-ID virtual-ip
virtual-address
Delete a virtual IP address undo vrrp vrid virtual-router-ID
[ virtual-ip virtual-address ]
The virtual-router-ID covers the range from 1 to 255.
