Hi ROS/Mikrotek don't do multi chasis lag. AFAIK They do have LACP, VRRP but no MLAG. MLAG is the ability to do LACP across 2 physical devices. Definitely find MLAG and separate switches is much better than stacked switches.

Hi Paul! Yes - routerOS supports link aggregation in several forms (check 'trunk' tab from 'switch -> ports' menu in winbox, or '/interface ethernet switch trunk' in shell. For routerOS implementation, see 'Interface Bonding' under interfaces menu in winbox, or "interface bonding" from shell) Not sure what you mean by redundancy - if you mean that bonded interface will continue to work if one of the links fails, then yes - that is also supported in several forms. There are some examples for this for CRS here: http://wiki.mikrotik.com/wiki/Manual:CRS_examples#Trunking Hope it's helpful! :-) Cheers, Mike.

Hi,

Is it possible in some form of configuration to have a pair of say CRS226 operating in a stack-like fashion, so as to say do a LAG to another pair of switches for redundancy.

ie:

[CRS-SW01] [SWITCH-01]

|| |_______________|

|| || ( LAG-01 )

||

[CRS-SW02] [SWITCH-02] |_______________|

Sorry if that diagram doesn't render properly

thanks !

Paul Arch
