Covers ~80% of CCNA labs by reconfiguration. PingLabz standardized IP scheme. v3 - includes admin and sysadmin users with Cisco@123 password for PyATS automation alongside the documented pinglabz user. notes: |- PingLabz CCNA Base Topology (v3) ================================ PURPOSE The reusable foundation for the PingLabz CCNA Labs membership section. VERSION HISTORY - v1: 2 unmanaged switches. Replaced - no managed switch CLI. - v2: SW1 upgraded to ioll2-xe (managed L2 switch). - v3: Added admin/Cisco@123 + sysadmin/Cisco@123 users so PyATS automation reaches the nodes via the CML controller. pinglabz/PingLabz!23 remains the documented user the reader logs in with.
