Foundry IKE and IPSec Defaults
To minimize configuration required by the user, default IKE and IPSec values have been implemented in
Foundry’s encryption scheme. Foundry supports a maximum of 100 IPSec tunnels.
IKE Defaults
Table 15.5: lists IKE defaults. When the user creates an IKE policy specifying an IKE peer, an IKE proposal with
priority 1 is automatically created. However, to make the IKE policy fully functional, the user must enter a pre-
shared key.
