Enabling the trap function of VRRP
After the trap function is enabled for a VRRP module, the VRRP module will generate traps with severity
level errors to report its key events. The generated traps will be sent to the information center of the LB
module, where you can configure whether to output the trap information and the output destination. For
more information about information center configuration, see System Management Configuration
Guide.

Single VRRP group configuration example
1. Network requirements
• Host A needs to access Host B on the Internet, using 202.38.160.111/24 as its default gateway.
• LB A and LB B belong to VRRP group 1 with the virtual IP address of 202.38.160.111/24.
• If LB A operates normally, packets sent from Host A to Host B are forwarded by LB A; if LB A fails,
packets sent from Host A to Host B are forwarded by LB B.
