Point-to-point communication

As explained in Acing the CCNA Exam: Volume 1 Fundamentals and Protocols

An RSTP point-to-point link is a full-duplex link whose connected ports can use the RSTP synchronization mechanism to transition rapidly to forwarding.

An RSTP point-to-point link is a full-duplex connection between switch ports. Because the ports can use RSTP synchronization, they can transition rapidly to forwarding instead of following the slower standard STP process. section 15.3

Recognize and configure the link type:

• Full-duplex ports automatically use the point-to-point type. section 15.3
• Manually configure an interface with spanning-tree link-type point-to-point in interface configuration mode. section 15.3
• A show spanning-tree entry marked P2p identifies a point-to-point link; P2p Edge additionally indicates PortFast on a full-duplex end-host connection. section 15.3

Figure 15.7 RSTP differentiates between three link types: point-to-point, shared, and edge. A full-duplex link is considered a point-to-point link. A half-duplex link is considered a shared link. A link between a switch and an end host that uses PortFast is considered an edge link.

Compare point-to-point, shared, and edge links by duplex mode, connected device, and RSTP behavior. section 15.3

How Acing the CCNA Exam: Volume 1 Fundamentals and Protocols covers it

How deep it goes

Defines duplex requirements, explains synchronization behavior, shows status output, and provides manual configuration.

Examples

Uses SW1 and SW2 full-duplex ports, Cisco show spanning-tree output, and P2p or P2p Edge status labels.

What it assumes

Recognizes full-duplex operation and basic RSTP port-transition behavior.

What you can do after

Apply it via Cisco interface configuration and verify the resulting P2p status with show spanning-tree.

How it connects

Connects RSTP synchronization with shared links, edge links, PortFast, and standard STP forwarding behavior.
