13. Under Hub to Spoke 1, configure how the hub and spoke 1 modules
authenticate each other.
a. For Authentication Method, select one of the following:
– Preshared Key
– DSA Signature
– RSA Signature
If you select DSA Signature or RSA Signature, you can go directly to
step 8. (After you finish the wizard, you must install certificates as
described in “Manage Certificates” on page 4-394.)
If you want to use SCEP to install certificates, select RSA Signature
rather than DSA Signature.
b. If you selected Preshared Key, type a string of 12 to 49 alphanumeric
or special characters in the Preshared Key box. Type the same string
in the Confirm Preshared Key box.
