Document bridge support for flooding ieee-reserved (e.g., LLDP) #788

Closed jovatn closed 1 week ago

jovatn commented 2 weeks ago

We lack an example showing how to make a bridge flood LLDP rather as opposed to snoop them.

One could add such an example to the Bridge section, possibly as a subsection on same level as MAC Bridge and VLAN Bridge?

Ideas below. Probably good to add a lego picture as well with a bridge and four Ethernet ports, illustrating that LLDP packet will be flooded.

admin@example:/config/interface/br0/> set bridge ieee-group-forward <TAB>
