Let me summarize some of the key takeaways related to Implement and Troubleshoot PPP as relevant to CCIE Routing and Switching (R&S) V5.1 written exam blueprint topics.
Implement and Troubleshoot PPP Exam Essentials
- CHAP authentication method depends on a “secret” known only to the authenticator and the peer. CHAP secret is never sent over wire.
- The PPP Endpoint Discriminator Option represents identification of the system transmitting the packet. This option advises a system that the peer on this link could be the same as the peer on another existing link (RFC 1990).
- Initial CHAP challenge packet includes both name of the challenger and packet type ID.
