Routers

• 2 Juniper routers
  • Were MX80s, upgraded to MX204s (this meeting)
    • Convergence: ~25 minutes -> ~1.5 minutes
• Core routers for network
  • BGP (eBGP, iBGP)
    • RPKI
  • OSPF / OSPFv3
  • DHCP relay / RA
  • BCP38
  • Passive ARP learning (more if we have time...)

Switches

• 2 x Cisco Catalyst 4500X Core stacked
• 10 x Cisco IDF switches
• 40 x Cisco 12 port switches
   
• "Joe's magic..."
  • Y'all keep plugging in DHCP servers :-(

  • A new switch to a fully provisioned switch in ~15 minutes (including a software upgrade).

  • Rooms are dynamic - this means we need to reconfigure things often and quickly

Switch Automation

• Feature-wise, the switch automation includes:
  • Initialize new switch with desired config and software image
  • Validation of config and image (checksum)
  • Auto-generation of SSH host key
  • Call-home for when a switch should re-ZTP
  • Auto-detection of connected device type (switch, AP, probe)
  • Port auto-config and auto-doc update
  • Detection of lost device and port description update
