In thesmall and midsize campus network designbased on theHuawei CloudCampus Solution, when over100 branchesneed to communicate with each other, which of the following interconnection networking models is recommended?
✔Hub-Spoke networkingis the mostefficient and scalablemodel for interconnecting100+ branchesin asmall and midsize campus network.
✔Why Hub-Spoke?
Centralized Control:Ahub routermanages communication betweenspoke routers(branch sites).
Reduced Complexity:Unlikefull-mesh, which requiresN(N-1)/2* connections,hub-spoke minimizes link costs.
Easier Management:Policy enforcement and security are centralized at thehub site.
✔Why Not Other Options?
❌A (Direct Networking)→ Suitable forsmall networks, but inefficient for100+ branches.
❌B (Full-Mesh Networking)→ Highcost and complexity, requiringtoo many links.
❌D (Partial-Mesh Networking)→ More scalable thanfull-mesh, buthub-spoke is more optimizedfor large branch networks.
