The cost variable will certainly play a big role in this. If the channel
between the 2 core switches is gig, then the root port of S2 will be
pointing to C2.
One of the ports between S1 and S2 will be in blocking ( this will depend
on which one is selected as the DP). If S1 has a lower BridgeID than S2,
then the port on S2 facing S1 will be blocking.
Therefore, your traffic will be flowing like that: S2-C2-C1

Subject: spanning-tree question
hi all,
topology
core1 --- channel to c2
link
switch1
link
switch2
link
core2 --- channel to c1
suppose i take two switches, each with a trunk to 1 core switch and a link
between them.
the vlan's spanning-trees are tuned as primary and secondary on each core.
there is also an etherchannel between the 2 core's
suppose a host on switch2 needs to send a frame to a vlan tuned for primary
on
core1.
and the opposite as well.
traffic should follow the link between the 2 switches right?
