VIP (Virtual Server IP) Address

An IP address that the switch owns and uses to load balance particular service requests (like HTTP) to other servers.

Virtual Router

A shared address between two devices utilizing VRRP, as defined in RFC 2338. One virtual router is associated with an IP interface defined on the Nortel Application Switch. All IP interfaces on a Nortel Application Switch must be in a VLAN. If there is more than one VLAN defined on the Application Switch, then the VRRP broadcast will only be sent out on the VLAN to which the associated IP interface has been added.

Virtual SSL Server

A virtual SSL server handles a specific service on the VPN Gateway, such as HTTPS, SMTPS, IMAPS, or POP3S. You can create an unlimited number of virtual SSL servers per NVG cluster, and each virtual SSL server is mapped to a virtual server on the Nortel Application Switch. To authenticate itself towards clients making requests for the specified service, the virtual SSL server is configured to use a digital certificate.

VLAN (Virtual Local Area Network)

VLANs are commonly used to split up groups of network users into manageable broadcast domains, to create logical segmentation of workgroups, and to enforce security policies among logical segments. Up to 246 VLANs are supported on a Nortel Application Switch running Web OS.

VRRP (Virtual Router Redundancy Protocol)

A protocol similar to Cisco’s proprietary HSRP address-sharing protocol. The reason for both of these protocols is to ensure devices have a next hop or default gateway that is always available. For example, two or more devices sharing an IP interface are either advertising or listening for advertisements. These advertisements are sent through a broadcast message to address 224.0.0.18.

With VRRP, one switch is considered the master and the other is the backup. The master is always advertising through the broadcasts. The backup switch is always listening for the broadcasts. Should the master stop advertising, the backup will take over ownership of the VRRP IP and MAC addresses as defined by the specification. The switch announces this change in ownership to the devices around it by way of a gratuitous ARP and advertisements. If the backup switch didn’t do the gratuitous
