You can configure Rapid Spanning-Tree Protocol (RSTP) under the following hierarchy
level:
[edit protocols]
To configure the Rapid Spanning-Tree Protocol:
Enable RSTP as the version of spanning-tree protocol to be configured:
1.
[edit]
user@host@ edit ... protocols rstp
Configure the interfaces that participate in the RSTP instance.
2.
Enable configuration of the interface:
a.
[edit ... protocols rstp]
user@host# edit interface interface-name
Configure the interface priority:
b.
[edit ... protocols rstp interface interface-name]
user@host# set priority interface-priority
(Optional) By default, the interface link cost is determined by the link speed. You
c.
can configure the interface link cost to control which bridge is the designated bridge
and which port is the designated port:
[edit ... protocols rstp interface interface-name]
user@host# set cost interface-link-cost
(Optional) Configure the interface as an edge port:
d.
[edit ... protocols rstp interface interface-name]
user@host# set edge
Edge ports do not expect to receive bridge protocol data unit (BPDU) packets. If
a BPDU packet is received for an edge port, the port becomes a nonedge port
Configure the bridge priority
3.
[edit ... protocols rstp]
user@host# set bridge-priority bridge-priority
