Which of the following are types of VPN communities?

Pentagon is not a defined VPN community type in Check Point; the term has no meaning in this topology context.

Octagon is not a defined VPN community type in any Check Point documentation.

This answer omits Meshed communities entirely and incorrectly uses 'Combined' instead of 'Combination', making it incomplete and inaccurate.

Check Point defines three VPN community types: Meshed, where all gateways encrypt traffic to every other gateway; Star, where spoke gateways communicate only through a central hub; and Combination, which mixes meshed and star topologies within a single community. These are the officially documented community types in Check Point VPN architecture.
