• Belongs to some of the LAN or Client subnets, in which case some clients are flat and some are routed. In such network configurations it is recommended to use both methods described above, and inform the users about the VIPs they need to use, depending on whether they are flat or routed. It is recommended to define an entry in the DNS for every subnet that the system belongs to, so that clients can access the data without remembering the VIPs. If there are multiple VIPs in the subnet, define a single name in your DNS server that issues IP addresses from that list in a round-robin fashion and that all the clients can access the system. NOTE: Do not intermix VIPs from different subnets in a single DNS name. Performance And Static Routes Routed networks provide an opportunity to enhance performance through a feature called static routes. This feature allows you to configure the exact paths in which the system communicates with various clients on a routed network. Figure 4. Network Configuration Consider the above network, there can be only one default gateway for the system. Assume that you select router X. Packets that are sent to clients in subnet Y would be routed to router X, which would then be sent back (through the switch) to router Y. These packets travel through router X needlessly, reducing the throughput to all subnets in your network. 62

Belongs to some of the LAN or Client subnets, in which case some clients are flat and some are routed. In such
network configurations it is recommended to use both methods described above, and inform the users about the
VIPs they need to use, depending on whether they are flat or routed.
It is recommended to define an entry in the DNS for every subnet that the system belongs to, so that clients can access
the data without remembering the VIPs. If there are multiple VIPs in the subnet, define a single name in your DNS server
that issues IP addresses from that list in a round-robin fashion and that all the clients can access the system.
NOTE:
Do not intermix VIPs from different subnets in a single DNS name.
Performance And Static Routes
Routed networks provide an opportunity to enhance performance through a feature called static routes. This feature
allows you to configure the exact paths in which the system communicates with various clients on a routed network.
Figure 4. Network Configuration
Consider the above network, there can be only one default gateway for the system. Assume that you select
router X
.
Packets that are sent to clients in subnet Y would be routed to router X, which would then be sent back (through the
switch) to router Y. These packets travel through router X needlessly, reducing the throughput to all subnets in your
network.
