3550----------gigstack------------3550
as we all know when a switch is enabled for uplink fast. it increases the
cost of all ports to stay above 3000 to prevent the port becoming a root
port and we also need to disable vlan prioroty before putting a switch into
uplink fast...right,
assuming you connect two 3550 routers with a gig stack and enable gigstck
uplink fast - aka cross stack uplink fast.. now all the vlan priorities will
be reset to 0 and all port cost will be set to be more than 3000 . as there
are only two switches one of them needs t0/will become a root for all the
vlans....
what could you possible do to make switch 1 the root for all odd vlans and
switch 2 to be root for all even vlans..
isnt this intersting...
scenario-2
3550----------gigstack-------------3550
-----------gig-trunk-----------
assuming you run a gigstack and a trunk bettwen two swithces...how will this
behave?
any ideas
cheers! sen
