List of terms
virtual router redundancy protocol (VRRP)
A protocol that specifies an election protocol that dynamically assigns responsibility for a virtual router to one of the VRRP routers on a LAN.
virtual router redundancy protocol backup (VRRP backup)
The set of VRRP routers available to assume forwarding responsibilities for a virtual router should the current master router fail.
virtual router redundancy protocol MAC address (VRRP MAC address)
A unicast MAC address associated with each VRRP virtual router that is used as a source MAC address for the VRRP advertisements. The VRRP master uses this address instead of its physical MAC address in all communications, for example: ARP response.
virtual router redundancy protocol master (VRRP master)
The VRRP router that assumes the responsibility of forwarding packets sent to the IP address(es) associated with the virtual route and answers ARP requests for these IP addresses.
virtual router redundancy protocol router (VRRP router)
A virtual router that runs the virtual router redundancy protocol. This virtual router may have more than one instance of VRRP provisioned.
virtual source/virtual destination (VS/VD)
The endpoints of the shortened loops. ABR relies on circuit loops with source and destination nodes to originate and turnaround resource management cells. Service providers can subdivide an ABR circuit into short loops as a way to reduce loop length or to avoid
