SPN Connector Concept
SecNumCloud Connectivity - SPN Connector Concept
Last updated 18th November, 2021
Objective
SPN Connector is the mecanism to assemble and inter-connect SPN of differents SecNumCloud zones and/or with VPN-SPN. This guide explains the concepts to understand its behavior.
Instructions
Basic rules
SPN can route trafic through SPN Connector:
- With another SPN in another Zone.
- With a VPN-SPN.
- NOT between two SPN of the same Zone.
- An SPN can not be connected to two SPN Connector.
All routes are forwarded through SPN Connector, no ACL/filtering is possible.
InterDC option
By default, SPN Connector can only inter-connect "local" SPN and VPN-SPN.
InterDC option: upgrade SPN Connector to "global" mode to allow connection between different zones.
Inter-connection of two SPN connector (global or local) is not supported.
InterDC uses dedicated and secured optical lines using MACsec protocol.
InterDC does not allow extension:
- of an SPN;
- of a VPN-SPN;
- of a Subnet.
Only forwarding of IP traffic (i.e routing) is supported through InterDC/SPN Connector.
