(Optional) Configuring the VRRP Version Number
Context
IPv4 VRRP supports VRRPv2 and VRRPv3. If devices in a VRRP group use different VRRP versions, VRRP Advertisement packets will fail to be forwarded.
- A VRRPv2 group can send and receive only VRRPv2 Advertisement packets, and discards received VRRPv3 Advertisement packets.
- A VRRPv3 group can send and receive both VRRPv2 and VRRPv3 Advertisement packets. You can configure the mode in which VRRPv3 Advertisement packets are sent. The mode can be v2-only, v3-only, or v2v3-both.
Procedure
- Run system-view
The system view is displayed.
- Run vrrp version { v2 | v3 }
The VRRP version number is set.
By default, VRRPv2 is used.
If VRRPv3 is used, run the vrrp version-3 send-packet-mode { v2-only | v3-only | v2v3-both } command to set the mode in which VRRPv3 Advertisement packets are sent. The default mode is v3-only.
