IPv6-based VRRP configuration examples
This section provides these configuration examples:
• Single VRRP group configuration example
• VRRP interface tracking configuration example
• VRRP with multiple VLANs configuration example
Single VRRP group configuration example
Network requirements
• Switch A and Switch B belong to VRRP group 1 with the virtual IP addresses of 1::10/64 and
FE80::10.
• Host A wants to access Host B on the Internet, and learns 1::10/64 as its default gateway through
RA messages sent by the switches.
• When Switch A operates normally, packets sent from Host A to Host B are forwarded by Switch A;
when Switch A fails, packets sent from Host A to Host B are forwarded by Switch B.
