  description: 'PingLabz CCNA Pillar 2 (Network Access) Reference Topology v2 - 3 IOSvL2 switches in a triangle with VLANs 10/20/99, dot1q trunks, rapid-PVST root election (SW1 root, SW2 backup), LACP EtherChannel between SW1 and SW2, plus a module-1 port bank (Gi1/0-1/3) per switch: Gi1/0 is a pre-wired second EtherChannel member (shutdown until lab na-06) and Gi1/1-1/3 are spare access ports. Used for na-01 through na-10 in the CCNA Labs library.'
  notes: "PingLabz STP and VLAN Reference Lab (v2)\n=========================================\n\nUsed as the canonical Pillar 2 lab for the PingLabz CCNA Labs library:\nna-01 through na-10 build on this topology.\n\nVERSION HISTORY\n- v1: 4 ports per switch. Replaced - labs na-02/04/05/06 need spare ports and\n  a second SW1-SW2 link, and IOSvL2 names module-1 ports Gi1/x (Gi0/4+ does\n  not exist on this platform).\n- v2: Added Gi1/0-1/3 to every switch. SW1 Gi1/0 <-> SW2 Gi1/0 is wired as the\n  second EtherChannel member (ships shutdown; brought up in na-06).\n  Gi1/1-1/3 are spare access ports (shutdown). Added explicit VLAN 99 root\n  priorities (SW1 4096 / SW2 8192) so root guard in na-10 has a clean steady\n  state on every import.\n\nTOPOLOGY\n   SW1 ---Gi0/0--------- Gi0/0 SW2\n   SW1 Gi0/1 ----Gi0/0 SW3 Gi0/1---- Gi0/1 SW2\n   SW1 Gi0/3 ============== Gi0/3 SW2   (LACP EtherChannel Po1)\n   SW1 Gi1/0 -------------- Gi1/0 SW2   (second Po1 member - shutdown, na-06)\n\nVLANS\n- 10\
    \ DATA / 20 VOICE / 99 NATIVE (native VLAN on all trunks)\n\nSTP\n- mode: rapid-pvst\n- SW1 priority 4096 for VLANs 10, 20, 99 (explicit primary root)\n- SW2 priority 8192 for VLANs 10, 20, 99 (explicit backup root)\n- SW3 priority default 32768 (leaf)\n\nNODE COUNT (CML Free)\n- 3 counted (all 3 iosvl2 switches). 2 slots free.\n\nNOTE ON MAC ADDRESSES\n- IOSvL2 interface and bridge MACs (5254.00xx.xxxx) are assigned dynamically\n  per import. Your bridge IDs, CAM entries, and DTP/LACP neighbor IDs will\n  differ from the lab articles; the structure is what matters.\n"
