Foundry Switch and Router Installation and Configuration Guide
NOTE: If your Foundry routers already are using FSRP and you do not need redundancy with devices that
cannot use FSRP, you do not need to reconfigure your routers to use VRRP.
Foundry Networks recommends that you do not use VRRP and FSRP on the same device.
Configuring FSRP
To begin using FSRP on the router:
1. Enable operation of FSRP on the router.
2. Configure FSRP parameters on physical or virtual interfaces for those IP sub-nets for which a redundant path
is desired. Configure the virtual router IP address and the other router's IP address.
3. Assign track ports, if appropriate.
4. Assign one of the routers to serve as the active router using the preference parameter, as appropriate.
5. Modify interface parameters, keep-alive-time, and router-dead-interval on both routers as required.
NOTE: You initially enable FSRP at the global CONFIG level of the CLI using the router fsrp command. All
other parameters are assigned or modified at the interface level of the CLI using ip fsrp address <ip-addr>
[<parameter>] commands.
NOTE: If you are using the Web Management interface, you enable FSRP on the System configuration panel.
All other parameters (interface) are configured on the FSRP configuration panel.
Configuration Rules for FSRP
• Virtual interfaces cannot be assigned as track ports.
• The keep-alive-time value must be set to the same value on both the active and standby router when both
routers are connected to the same sub-net.
• The router-dead-time parameter must be set to the same value on both the active and standby routers when
both routers are connected to the same sub-net.
Enable FSRP on the Router
Before configuring FSRP to provide redundancy for a router, you must enable the feature on the router.
USING THE CLI
To enable FSRP on a router, enter the following command:
NetIron(config)# router fsrp
USING THE WEB MANAGEMENT INTERFACE
1. Log on to the device using a valid user name and password for read-write access. The System configuration
dialog is displayed.
2. Select the Enable radio button next to FSRP.
3. Click the Apply button to apply the change to the device's running-config file.
4. Select the Save link at the bottom of the dialog. Select Yes when prompted to save the configuration change
to the startup-config file on the device's flash memory.
