Foundry Configuration Guide for the FESX, FSX, and FWSX
5 - 4 © Foundry Networks, Inc. December 2005
The hw-logical-interface <num> parameter specifies the number of hardware logical interface pairs (physical
port and VLAN pairs) supported on the device. Enter a number from 0 to 4096. When this parameter is set to
4096 (the maximum), the limit is not enforced. If you enter a number less than 4096, the limit is the total number
of physical port and VLAN pairs that are IP-enabled in the system. The default is 4096.
The hw-ip-mcast-mll <num> parameter specifies the maximum number of multicast output interfaces (clients)
supported on the device. If a given source or group has clients in n tagged VLANs on the router, then n + 1 mll
entries are consumed for that source or group entry. Enter a number from 0 to 4096. The default is 1024.
Displaying Layer 3 System Parameter Limits
To display the Layer 3 system parameter defaults, maximum values, and current values, enter the following
command at any level of the CLI:
Configuring RIP
RIP is disabled by default. If you want the Foundry device to use RIP, you must enable the protocol globally, then
enable RIP on individual ports. When you enable RIP on a port, you also must specify the version (version 1 only,
version 2 only, or version 1 compatible with version 2).
Optionally, you also can set or change the following parameters:
• Route redistribution – You can enable the software to redistribute static routes from the IP route table into RIP.
Redistribution is disabled by default.
• Learning of default routes – The default is disabled.
• Loop prevention (split horizon or poison reverse) – The default is poison reverse.
Enabling RIP
RIP is disabled by default. To enable it, use the following CLI method. You must enable the protocol both globally
and on the ports on which you want to use RIP.
To enable RIP globally, enter the following command:
