Configuring LINUX Servers in DSR Mode
The LINUX operating system requires that you set up a loopback interface with the NetScaler appliance virtual IP address (VIP) on each load balanced server in the DSR cluster.
To configure LINUX server in DSR mode
To create a loop back interface with the NetScaler appliance’s VIP on each load balanced server, at the Linux OS prompt type the following commands:
ifconfig dummy0 up
ifconfig dummy0:0 inet
echo 1 > /proc/sys/net/ipv4/conf/dummy0/arp_ignore
echo 2 > /proc/sys/net/ipv4/conf/dummy0/arp_announce
Then, run the software that re-maps the TOS id to VIP.
Note: Add the correct mappings to the software before running it. In the preceding commands, the LINUX server uses dummy0 to connect to the network. When you use this command, type the name of the interface that your LINUX server uses to connect to the network.
