Jeremy's It Lab CCNA Rapid STP Day 22

Configure a switchport as an RSTP edge port:

SW1(config-if)# [...]

spanning-tree portfast

Configure a switchport as an RSTP point-to-point port:

SW1(config-if)# [...]

spanning-tree link-type point-to-point

Configure a switchport as an RSTP shared port:

SW1(config-if)# [...]

spanning-tree link-type shared

Enable rapid PVST mode on the switch:

SW1(config)# [...]

spanning-tree mode rapid-pvst

In RSTP, a switch considers a neighbor lost if it misses [...] BPDUs.

3

In RSTP, which switch(es) originate BPDUs?

All switches

Is RSTP compatible with classic STP?

The RSTP [...] port role functions as a backup to a designated port.The RSTP [...] port role functions as a backup to a designated port.

backup

The RSTP [...] port role functions as a backup to the root port.

alternate

The RSTP [...] port role is a discarding port that receives a superior BPDU from another switch.
