encr_algs Security Option

This option enables IPsec ESP for a tunnel with a specified encryption algorithm. The encr_algs option has the following format:

encr_algs encryption-algorithm

For the algorithm, you can specify either a number or an algorithm name. To disable tunnel security, specify the following option:

encr_algs none

If you specify an ESP authentication algorithm, but not an encryption algorithm, ESP's encryption value defaults to the parameter null.

For a list of available encryption algorithms, run the ipsecalgs command.
