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.

SPN connector rules

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.

InterDC rules

Inter-connection of two SPN connector (global or local) is not supported.

InterDC uses dedicated and secured optical lines using MACsec protocol.

SPN InterDC HLD

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.
