Single VRRP Group Configuration Example
Network requirements
• Host A needs to access Host B on the Internet, using 1::10/64 as its default gateway.
• Device A and Device B belong to VRRP group 1 with the virtual IPv6 addresses of 1::10/64 and
FE80::10.
• If Device A operates normally, packets sent from Host A to Host B are forwarded by Device A; if
Device A fails, packets sent from Host A to Host B are forwarded by Device B.
