4. Configure hello BPDU timers.
a. Configure the maximum expected arrival time of hello BPDUs:
[edit ... protocols rstp]
user@host# set max-age seconds
b. Configure the time interval at which the root bridge transmits configuration BPDUs:
[edit ... protocols rstp]
user@host# set hello-time seconds
5. (Optional) By default, the bridge port remains in the listening and learning states for
15 seconds before transitioning to the forwarding state. You can specify a delay from
4 through 20 seconds instead:
[edit ... protocols rstp]
user@host# set forward-delay seconds
6.
Verify the RSTP configuration:
[edit]
protocols {
rstp {
force-version stp; # Optional.
bpdu-destination-mac-address provider-bridge-group; # Optional
extended-system-id identifier; # Optional.
interface interface-name {
priority interface-priority;
cost interface-link-cost; # Optional.
mode (p2p | shared);
edge; # Optional.
}
bridge-priority bridge-priority;
max-age seconds;
hello-time seconds;
forward-delay seconds; # Optional.
}
}
}
