Refer to the exhibit. This network is running legacy STP 802.1d. Assuming "hello_timer" is fixed to 2 seconds, which parameters can be modified to speed up convergence times after single link/node failure?
A.
Only the maximum_transmission_halt_delay and diameter parameters are configurable parameters in 802.1d to speed up STP convergence process.
B.
The max_age and forward delay parameters can be adjusted to speed up STP convergence process.
C.
The transit_delay=5 and bpdu_delay=20 are recommended values, considering hello_timer=2 and specified diameter.
D.
Only the transit_delay and bpdu_delay timers are configurable parameters in 802.1d to speed up STP convergence process.
The correct answer is B. The max_age and forward delay parameters can be adjusted to speed up STP convergence process.
Tune max age and forward delay Timers
Among all these parameters, the only ones that you can tune are:
hello — From 1 to 6
max age
forward delay
diameter — This depends on the network.
Do not modify any of the values in this list. Leave these values at the recommended IEEE value:
lost_msg = 3
transit_delay = 1
bpdu_delay = 1
msg_overestimate = 1
Tx_halt_delay = 1
med_access_delay = 0.5
maximum_transmission_halt_delay = 1
