hi, I have a problem with the equipment Cisco 3750-X (Version 15.0) and the REP protocol.
I have a ring with 3 nodes: A, B and C. Each node consists of two Cisco 3750-x in the stack.
I have configured the REP among the three nodes and it is all ok, no errors, as shown below:
BridgeName PortName Edge Role
----------------------------------
A Te2/1/1 Pri Open
B Te2/1/1 Open
B Te1/1/1 Open
C Te2/1/1 Alt
C Te1/1/1 Open
A Te1/1/1 Sec Open
(On all three routers show rep topology is ok).
Even the "show cdp neighbors" shows a correct result on all nodes: each node
"Sees" the other two.
The problem I have is that:
from A to C: ping ok
from A to B: ping failed
from C to A: ping ok
from C to B: ping failed
from B to C: ping failed
from B to A: ping failed
B is isolated (I can reach him via AUX port).
It seems that the trunk connected to B carries only the REP administrative VLAN (ID 191) and the default VLAN (as shown by CDP); it seems that no other traffic is transported.
Can someone help me?
