Lo scenario
A small business needs resilient WAN connectivity using two internet providers and three routers connected in a triangle. OSPF routes between edge and core routers, automatically failing over if an ISP or inter-router link goes down.
Cosa contiene questo disegno
Leggi le decisioni che ne stanno alla base.
01
Use three routers in a triangle to provide redundant WAN paths
02
Connect each edge router to a separate ISP for dual-homing
03
Run OSPF on all router links so failover is automatic
Reuse for any small-to-midsize branch or campus design where WAN uptime and router redundancy are required, especially with dual ISP uplinks.
