Network Requirements - HP A5830 series Configuration Manual

The output shows the BFD detection result: the next hop 10.2.1.2 is unreachable (the status of the track
entry is Negative), and the backup static route takes effect, and Switch A forwards packets to
30.1.1.0/24 through Switch C and Switch B.
# When the master route fails, the hosts in 20.1.1.0/24 can still communicate with the hosts in
30.1.1.0/24.

Network requirements

As shown in
•
A is 10.1.1.10/24.
Switch A and Switch B belong to VRRP group 1, whose virtual IP address is 10.1.1.10.
•
When Switch A works normally, packets from Host A to Host B are forwarded through Switch A.
•
When VRRP detects that a fault is on the uplink interface of Switch A through the interface
management module, packets from Host A to Host B are forwarded through Switch B.
