Disabled.
IP forwarding must first be enabled before IP broadcast forwarding can be enabled. When new IP interfaces are added, IP forwarding (and IP broadcast forwarding) is disabled by default.
The broadcast, ignore-broadcast, and fast-directbroadcast options each prompt with a warning message when executed while the IP forwarding on the corresponding VLAN is disabled. The hardware and software are NOT programmed until IP forwarding is enabled on the VLAN.
The fast-direct-broadcast and ignore-broadcast options cannot be enabled simultaneously. These are mutually exclusive.
The broadcast option can be enabled in conjunction with fast-direct-broadcast and ignore-broadcast.
The following command enables forwarding of IP traffic for all VLANs in the current VR context with IP addresses:
enable ipforwarding
The following command enables forwarding of IP broadcast traffic for a VLAN named accounting:
enable ipforwarding broadcast vlan accounting
This command was first available in ExtremeXOS 10.1.
