CASE ANALYSIS

Scenario

A three-router triangle topology connects Router A, Router B, and Router C in a redundant loop, with a server on Router A and a LAN switch/PC on Router B.

Key decisions

  • Model the three routers as a ring of three direct links for redundancy without a full mesh.
  • Attach server to Router A and LAN access switch to Router B to distribute endpoints.
  • Use ring layout to visually emphasize the triangular loop.

When to reuse this

Use for small WAN/core topologies where any router can route via two alternate paths but full mesh overhead is unnecessary.
