• RIPV1 and V2
• VRRP
• VRRP-E
• VSRP
• IPv6 Routing
• IPv6 Multicast
IP routing is enabled by default on devices running Layer 3 code. All other protocols are disabled, so you must enable them to congure
and use them.
To enable a protocol on a device running 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.
device(config)#router ospf
Syntax: router bgp | igmp | ip | ospf | pim | rip | vrrp | vrrp-e | vsrp
Enabling or disabling Layer 2 switching
By default, Brocade Layer 3 switches support Layer 2 switching. These devices modify 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.
NOTE
Consult your reseller or Brocade to understand the risks involved before disabling all Layer 2 switching operations.
Conguration notes and feature limitations for Layer 2 switching
• Enabling or disabling Layer 2 switching is supported in Layer 3 software images only.
• FastIron X Series,Brocade FCX Series, and ICX devices support disabling Layer 3 switching at the interface conguration level
as well as the global CONFIG level.
• Enabling or disabling Layer 2 switching is not supported on virtual interfaces.
Command syntax for Layer 2 switching
To globally disable Layer 2 switching on a Layer 3 switch, enter commands such as the following.
device(config)#route-only
device(config)#exit
device#write memory
device#reload
To re-enable Layer 2 switching on a Layer 3 switch, enter the following commands.
device(config)#no route-only
device(config)#exit
