Introduction

A router that learns its network address from a seed router shows 
a status of garnered; meaning you did not configure it.

If your network configuration requires you to connect two or more 
ATXs together, but the applications you are running over the 
network require more than a single LAN connection between 
ATXs, you can use the built-in trunking feature to increase 
bandwidth up to 8 times the single LAN connection bandwidth 
(128 Mpbs for Token Ring), without installing additional hardware 
on your network.

Trunking is a proprietary extension to the 802.1D Spanning Tree 
algorithm. It enables you to use multiple LAN segments to connect 
ATXs together, while maintaining first-in, first-out ordering of 
packets. In addition, if any of the LAN segments configured for 
trunking become inoperable, those LAN segments are 
automatically bypassed.

Trunking can be used between devices which support trunking. 
Currently, it is possible to connect Fast Network 10s to ATXs via 
Ethernet connections, ATX to ATX via Ethernet, Token Ring, or 
FDDI connections, or Fast Network 10s to Fast Network 10s.

Figure 1-13 below shows two ATXs connected by four 10BASE-T 
crossover cables. You can connect up to eight ports for sharing the 
traffic load. Any additional connected ports beyond the eight ports 
will become standby ports. A standby port is automatically 
included in a trunk group when a port currently in the trunk group 
becomes disabled. The connections must be point-to-point. That is, 
there cannot be any other devices on the trunked LAN segments.
