SPNGN1 1.0: PPP and SONET in the WAN

This course is targeted at networking engineers who must interface with Cisco IOS, IOS XR and IOS XE devices. Additionally, those who have a need to understand technologies used in the service provider realm will benefit.


Expected Duration
58 minutes

The Point-to-Point Protocol, or PPP, supports features such as authentication, which is useful in the connection between the service provider and customer edge. This protocol was once the native WAN encapsulation on this link but has become an auxiliary encapsulation to provide the feature of PPP to links such as Ethernet and ATM. Upstream of this connection toward the core of a service provider, SONET can often be found. Knowing the nature of SONET is useful to have a greater understanding of service provider core technologies. This course covers variants of PPP and SONET. This course is one of a series in the Skillsoft learning path that covers the objectives for the Cisco exam Building Cisco Service Provider Next-Generation Networks Part 1 exam (640-875 SPNGN1). This exam counts toward the CCNA Service Provider certification.
