Other Layer 3 Protocols

For information about other IP configuration commands in the Layer 2 with Base Layer 3 image that are not
included in this chapter, see the chapter "Configuring IP" on page 16-1.
For information about enabling or disabling Layer 3 routing protocols, see "Enabling or Disabling Routing
Protocols" on page 5-7. For complete configuration information about the routing protocols, see the other
chapters in this book.

Enabling or Disabling Routing Protocols

This section describes how to enable or disable routing protocols. For complete configuration information about
the routing protocols, see the other chapters in this book.
FESX and FSX devices running full Layer 3 code support the following protocols:
• BGP4
• IGMP
• IP
• IP multicast (DVMRP, PIM-SM, PIM-DM)
• OSPF
• RIPV1 and V2
• VRRP
• VRRPE
• VSRP
IP routing is enabled by default on devices running Layer 3 code. All other protocols are disabled, so you must
enable them to configure and use them.
NOTE: The following protocols require a system reset before the protocol will be active on the system: PIM,
DVMRP, and RIP. To reset a system, enter the reload command at the privileged level of the CLI.
To enable a protocol on a device running full Layer 3 code, enter router at the global CONFIG level, followed by
the protocol to be enabled. The following example shows how to enable OSPF:
FESX424 Router(config)# router ospf
FESX424 Router(config)# end
FESX424 Router# write memory
FESX424 Router# reload
Syntax: router bgp | dvmrp | ospf | pim | rip | vrrp | vrrpe | vsrp

Enabling or Disabling Layer 2 Switching

By default, Foundry Layer 3 Switches support Layer 2 switching. These devices switch the routing protocols that
are not supported on the devices. If you want to disable Layer 2 switching, you can do so globally or on individual
ports, depending on the version of software your device is running.

Configuration Notes

• Make sure you really want to disable all Layer 2 switching operations before you use this option. Consult your
reseller or Foundry Networks for information.
• This feature is supported in the following configurations:
• The FESX running software release 01.1.00 or prior, supports disabling Layer 2 switching on a global
basis only. Starting in release 02.1.01, the FESX supports disabling Layer 2 switching on an individual
