time to expire before it updates the priority and initiates the switchover if the priority is
higher than the priority for the VRRP master (original backup) router.
If the asymmetric-hold-time statement is not configured, the VRRP master waits for the
hold time to expire before it initiates a switchover when a tracked route goes down.
Here is an example for configuring asymmetric hold time:

user@host# set protocols vrrp asymmetric-hold-time

Configuring an Interface to Accept Packets Destined for the Virtual IP Address
In VRRP implementations where the router acting as the master router is not the IP
address owner—the IP address owner is the router that has the interface whose actual
IP address is used as the virtual router’s IP address (virtual IP address)—the master router
accepts only the Address Resolution Protocol (ARP) packets from the packets that are
sent to the virtual IP address. Junos OS enables you to override this limitation with the
help of the accept-data configuration. When the accept-data statement is included in
the configuration, the master router accepts all packets sent to the virtual IP address
even when the master router is not the IP address owner.
NOTE: If the master router is the IP address owner or has its priority set to
255, the master router, by default, accepts all packets addressed to the virtual
IP address. In such cases, the accept-data configuration is not required.
To configure an interface to accept all packets sent to the virtual IP address, include the
accept-data statement:
