Adding a Hub and Spoke Policy
In a hub and spoke network, all transmissions either originate from a hub network and are received by a
spoke network or originate from one of the spoke networks and are received by the hub network.
Figure 72 Secured hub and spoke example
● PEP A encrypts data traffic from network A that goes to Networks B or C. PEP A also decrypts data
that originates from Network B and C.
● PEP B encrypts data from network B that goes to network A and decrypts data that comes from
network A.
● PEP C encrypts data from network C that goes to network A and decrypts data that comes from
network A.
● PEP B and PEP C have no security associations to allow for decryption of traffic originating from
each other.
When you create a policy for a hub and spoke network, you must select at least one hub network set and
one spoke network set.
