System Administration Guide: IP Services


This option enables IPsec ESP for a tunnel, with the authentication algorithm specified. The encr_auth_algs option has the following format:

encr_auth_algs authentication_algorithm

For the algorithm, you can specify either a number or an algorithm name, including the parameter any, to express no specific algorithm preference. If you specify an ESP encryption algorithm, but you do not specify the authentication algorithm, the ESP authentication algorithm value defaults to the parameter, any.

See Table 19–1 for a list of available authentication algorithms and for pointers to the algorithm man pages.
