Subnetworks, Between | 3Com 6416SW instruction

Trunks	Between		Subnetworks
In	order	to	define a logical		link	between		switches in	different subnetworks, you must
also	use	the SET STATIC_ROUTE		command		to associate the address of the boundary
hub	in the		remote cluster	with	a	locally	defined ACN.
The	SET LOGICAL_LINK command then uses					this	ACN	to establish	the logical link with
the	remote cluster.
