CASE ANALYSIS

Scenario

A data center core network uses three routers in a full-mesh triangle to provide path redundancy and BGP peerings. A perimeter firewall connects to the internet and a DMZ switch hosting public-facing web and database servers.

Key decisions

  • Triangle full mesh among core routers for redundancy and BGP peerings
  • Perimeter firewall separates untrusted internet from DMZ and internal networks
  • DMZ switch isolates public servers in VLAN 50

When to reuse this

Use for documenting small to mid-size data center core routing topologies with a DMZ segment.
