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:
You can include this statement at the following hierarchy level:
- [edit interfaces interface-name unit logical-unit-number family inet address address vrrp-group group-id]
To prevent a master router that is the IP address owner or has its priority set to 255 from accepting packets other than the ARP packets addressed to the virtual IP address, include the no-accept-data statement:
