| | RFC 2338 (rfc2338) - Virtual Router Redundancy Protocol |
 | | A VRRP router may associate a virtual router with its real addresses on an interface, and may also be configured with additional virtual router mappings and priority for virtual routers it is willing to backup. | | | The router on the left becomes the Master for virtual router #1 (VRID=1) and the router on the right is the Backup for virtual router #1. | | | Virtual Router Master The VRRP router that is assuming the responsibility of forwarding packets sent to the IP address(es) associated with the virtual router, and answering ARP requests for these IP addresses. |

| | This new model uses the ATM fabric to emulate a multiprotocol bridge/router, and is sometimes referred to as the virtual router architecture. | | | A significant drawback of the current RFC 1577 specification, however, is the requirement for traditional packet-switch routers to be used to interconnect different subnets. | | | Therefore, any emulated LAN that contains Ethernet devices will force an MTU that will not be optimal for the ATM hosts in that emulated LAN. |

| | VLAN Information |
| | One drawback to this design is that routers add latency, which essentially delays the transmission of data. | | | It is still necessary to use a router when moving between broadcast domains, and in this example, the router interface is a member of all of the VLANs. | | | A router must use more of the data packet to determine destinations and route the data to the appropriate end node. |

| | Virtual LANs |
| | A VLAN is a switched network that is logically segmented by functions, project teams, or applications without regard to the physical location of users. | | | Routers are integrated into the switching fabric by using high-speed backbone connections over Fast Ethernet, FDDI, or ATM for higher throughput between switches and routers. | | | If one of the network segments in the spanning tree becomes unreachable, or if STP costs change, the spanning-tree algorithm reconfigures the spanning-tree topology and reestablishes the link by activating the standby path. |
