Once this configuration is in place, requests to the proxy are cycled across multiple proxies configured with the same virtual IP address. Such a configuration, which resides behind a device like a load balancer switch (Web cache redirector), can enable the implementation of a load balancing policy on the switch. These are used to host a virtual service such as proxy or an individual site rendered by the proxy. Secondary IP addresses with no ARP (Address Resolution Protocol) option are used to configure virtual IP addresses. These addresses have several uses, which are described in this section. Secondary IP addresses are additional addresses that can be used in order to configure multiple logical hosts on the same interface.

The figures that follow are a series of screenshots taken on a client logged in to the Novell Portal utility running on a remote server. Non-contiguous masks are not allowed per the recommendation in Section 2.1 of RFC 950 (see Figure 4). Subnet/ Supernet with non- contiguous bits in mask This configuration is allowed, but is not supported with a supernet mask routing functionality. Subnet/ Supernet with contiguous bits in mask This is interpreted as a broadcast to be directed to all subnets in the specified network. This is interpreted as a broadcast to be directed to the specified subnet.Д®xplicit configuration of this address is not allowed. This is interpreted as a broadcast to be directed to the specified network.Д®xplicit configuration of this address is not allowed.

When specified as a destination address, it is translated as a loopback address 127.0.0.1 (see Figure 3).Д®xplicit configuration of this address is not allowed. In NetWare it is internally maintained and used to represent an unspecified address in the connection table (see Figure 2) that its resolved to the first bound primary address in a particular network. This notation is similar to the notation in section 3.2 of RFC 1122.Д«asic configuration, which is mandatory to be supported.Д®xplicit configuration of this address is not allowed.This is internally treated as a broadcast when specified as a destination address.Д®xplicit configuration of this address is not allowed. The notation is used frequently to denote a particular address. The following table summarizes the cases for the configuration and usage of class A, B, C, and zero addresses using various address mask combinations. Each one represents a unique combination of Destination addresses and Interface numbers. The primary bindings are indicated by the entries labelled 'direct' in the routing table. These network interface associations are entered into the routing tables.ДЇigure 1 shows an example of a routing table for a NetWare server with five primary bindings.ДЇigure 1: Primary addresses as reflected in NetWare's routing table. Primary IP addresses are used to create a mapping between the attached networks and the physical interfaces on a system. This AppNote describes each of the above categories of configurations and presents the rules governing their usage in a NetWare environment. They can be categorized as follows:ДЄddress assignments for grouped interfaces In a TCP/IP-based network, various IP address configurations are possible.

Address Assignments for Grouped Interfaces.

It also compares the address assignment schemes to be provided with what has been set forth in various RFCs.

This AppNote describes all the possible IPV4 address assignments and related usage information for the TCP/IP protocol stack available in the next release of NetWare 6.5 (code-named Nakoma). Novell, thanks to B Thavamani Rajan from Novell for his assistance with this AppNote.
