Creating Vrrp Group And Configuring Virtual Ip Address - H3C S9500E Series Configuration Manual

•
Standard protocol mode: In a VRRP group, only the master forwards packets.
•
Load balancing mode: In a VRRP group, all switches (master and backups) that have AVF
can forward packets.
After you configure the working mode of a VRRP group, all switches in the VRRP group work in
the same mode.
To configure the VRRP working mode:
To do...
1. Enter system view
2. Configure VRRP to work in the
standard protocol mode
3. Configure VRRP to work in
load balancing mode

Creating VRRP group and configuring virtual IP address

You must configure a virtual IP address for a VRRP group when creating the VRRP group on an
interface. If the interface connects to multiple sub-networks, you can configure multiple virtual IP
addresses for the VRRP group, for router backup on different sub-networks.
A VRRP group is created automatically when you specify the first virtual IP address for the VRRP
group. If you specify another virtual IP address for the VRRP group later, the virtual IP address is
added to the virtual IP address list of the VRRP group.
H3C does not recommend creating VRRP groups on the VLAN interface of a super VLAN. Otherwise,
network performance may be affected.
Configuration prerequisites
Before creating a VRRP group and configuring a virtual IP address on an interface, you should
first configure an IP address for the interface and ensure that the virtual IP address to be
configured is in the same network segment as the IP address of the interface.
