Beginning
Requirements: USERNAME and PW created for PEERING/AUTHENTICATING DEVICES. eg– If R4 is connecting, a local user of R4 will need to exist. Passwords for authenticating devices will need to be consistent. No PW is sent over the WIRE. Only Hostname, magic#. CHAP uses it's local PW along with the hostname/Magic# of peering device and hashes it via MD5SUM. The MD5 hash is sent to each router. If the hash matches, the routers will authenticate and bring up the PPP link.
Clear text, no no no!
