Adding or removing route monitors
When the appliances of a high availability pair reside on different networks, the high availability state of NetScaler Gateway depends on if the appliance can be reached or not. In a cross-network high availability configuration, a route monitor on each NetScaler Gateway scans the internal routing table to make sure that an entry for the other NetScaler Gateway is always present.
To add a route monitor
In the configuration utility, on the Configuration tab, in the navigation pane, expand System and then click High Availability.
In the Bind/Unbind Route Monitors dialog box, on the Route Monitors tab, click Action, and then click Configure.
Under Specify Route Monitor, in Network, type the IP address of the network of the other NetScaler Gateway appliance.
To configure an IPv6 address, click IPv6 and then type the IP address.
In Netmask, type the subnet mask of the other network, click Add and then click OK.
When this procedure is complete, the route monitor is bound to NetScaler Gateway.
Note: When a route monitor is not bound to a NetScaler Gateway, the high availability state of either appliance is determined by the state of the interfaces.
To remove a route monitor
- In the configuration utility, on the Configuration tab, in the navigation pane, expand System and then click High Availability.
- On the Route Monitors tab, click Action, and then click Configure.
- Under Configured Route Monitors, select the monitor, click Remove and then click OK.
