VRRP interface tracking configuration example

Network requirements
Host A wants to access Host B on the Internet, using 202.38.160.1 1 1/24 as its default gateway.
•
• Switch A and Switch B belong to VRRP group 1 with the virtual IP address of 202.38.160.1 1 1/24.
If Switch A operates properly, packets sent from Host A to Host B are forwarded by Switch A. If
•
VLAN-interface 3 through which Switch A connects to the Internet is not available, packets sent from
Host A to Host B are forwarded by Switch B.
• To prevent attacks to the VRRP group from illegal users by using spoofed packets, configure the
authentication mode as plain text to authenticate the VRRP packets in VRRP group 1, and specify the
authentication key as hello.
