RSTP necessary for trunked Ports?

[Christiane Bogenstahl]

Hi all!
I want to configure 2 Ports to a Trunk
("trunk a1-a2 Trk1 trunk")

I want to do this for 2 HP Switches to connect Switch1 A1 to Switch2 A1
and
Switch2 A2 to Switch2 A2

The bandwidth should be doubled by this onfiguration.

The trunks on the Switches shall become part of one VLAN.

Do I have to configure STP or RSTP, too, to avoid Loopback on the switches? Or does it seem to the switches that they have only one linked connection?

If RSTP is necessary: Is it possible to configure RSTP just for the Trunk?

Thanks in advance and greetings
Chrissie

Little correction:

to connect Switch1 A1 to Switch2 A1
and
Switch1 A2 to Switch2 A2

When configuring a trunk, spanning tree is not necessary as a trunk group is seen as one interface.

However, configure the trunk group first, then connect the links between the switches second...otherwise you will have STP issue :-)
