Hi,
This is a physical topology of network.
------------------------| | | | layer | | 2 | | Switch 1 |------------------------ -------------------- | | | | | | | | | ------------------------|
-------------------- | | | layer
2 | | layer |-----------------| switch (3) | | 2 | | | | Switch (2) | | | ------------------------------------------- | | | | | | - | | | | | PC1 pc2 pc3
Now , by this topology a loop is formed among 3 of the above switches. So after spanning tree performed a loop free (logical) topology formed which look like......
------------------------| | | root switch | layer | | 2 | | Switch 1 |-------------------------------------- desgnated port
-------------------- | | desgnated port | | | | | | X (this path is blocked by STP)
-------------------------|
-------------------- | | | layer 2 | | layer |--------------------------| switch (3) | | 2 | desgnated port | | | Switch 2 | | |
------------------------
-------------------- | | | | | | - | | | | | PC1 pc2 pc3
Now my question is , weather the ports for 3 hosts (pc1, pc2 and pc3) of switch 2 are also became designated port. And why????
