This configuration example creates a loop-free topology between four EX Series switches
using RSTP.
An RSTP topology contains ports that have specific roles:
•
The root port is responsible for forwarding data to the root bridge.
•
The alternate port is a standby port for the root port. When a root port goes down, the
alternate port becomes the active root port.
•
The designated port forwards data to the downstream network segment or device.
•
The backup port is a backup port for the designated port. When a designated port goes
down, the backup port becomes the active designated port and starts forwarding data.
NOTE:
You also can create a loop-free topology between the aggregation
layer and the distribution layer using redundant trunk links. For more
information about configuring redundant trunk links, see “Example:
Configuring Redundant Trunk Links for Faster Recovery” on page 1343.
