VSRP 2
In VSRP setup, there are always at least two VSRP switches for each VSRP instance. A passive
device should always have either one access link or one trunk link connected with each VSRP
switch for each VSRP instance. This can create a black hole scenario. A black hole is when VSRP
failover causes data traffic from the switches/hosts which connect to VSRP passive switch to go
nowhere.
VSRP 2 can detect the health of each pair/set of links for each VSRP instance.VSRP 2 detects
which link of VSRP backup switch not receiving any advertisement for specific time duration. The
VSRP backup switch can treat the link of the pair on the master side is down or broken and set its
own link of the pair in forwarding state. The VSRP backup switch sends out gratuitous ARP for VSRP
master only to this link. Other links of other VSRP instances in VSRP backup switch are still in
blocking state as shown in figure Figure 164,Figure 165, and Figure 166.
