Re: Using trunk(4) to put a router in a switch ring

well i think you could insert your dual NIC openbsd host into the switch 'ring' physically, then bridging between the 2 NICs and firing up STP, but be aware that every time you up/down an interface or reboot your openbsd box, you'll trigger an STP recalc - which is around 45sec outage

1. create a layer 2 (switched) ring, using spanning tree. - completely independent of openbsd box 2. connect your (dual NIC) openbsd box to 2 separate switches for redundancy, and add both NICs to a trunk group. - redundancy of switch, cabling and NICs. [EMAIL PROTECTED]

Using trunk(4) to put a router in a switch ring

2008-09-22 Thread Dave Wilson
I am trying to work out a way to add some redundancy to my network, by putting my switches in a ring. I have a pair of CARP'd routers, each with 2 GigE interfaces, and the ability to add more on PCI-E cards. I have a number of switches with 24x100Mb ports and 2 GigE uplink ports. Currently
