VRRP-Track-interface management collaboration
configuration example
Network requirements
As shown in Figure 49:
• Host A requires access to Host B. The default gateway of Host A is 10.1.1.10/24.
• Switch A and Switch B belong to VRRP group 1. The virtual IP address of VRRP group 1 is
10.1.1.10.
Configure VRRP-Track-interface management collaboration to monitor the uplink interface on the
master and meet the following requirements:
• When Switch A operates correctly, it forwards packets from Host A to Host B.
• When VRRP detects a fault on the uplink interface of Switch A through the interface
management module, Switch B forwards packets from Host A to Host B.
