Description

Enable and configure server to member communication. When these options are configured, group members receive new keys before current keys expire. Starting with Junos OS Release 15.1X49-D80, the minimum value that you can configure for the lifetime-seconds option is 300 seconds instead of 180 seconds.

Options

  • certificate certificate-id—Specify the certificate identification. Only RSA keys are supported.

  • communication-type—Configure unicast (the default).

  • encryption-algorithm—Encryption used for communications between the group server and group member. Specify aes-128-cbc, aes-192-cbc, or aes-256-cbc.

  • lifetime-seconds seconds—Lifetime, in seconds, of the key encryption key (KEK). Specify a value from 300 to 86,400. The default is 3600 seconds.

  • number-of-retransmission number—For unicast communications, the number of times the group server retransmits messages to a group member when there is no reply. Specify a value from 0 to 60. The default is 2.

  • retransmission-period seconds—The time period between a transmission and the first retransmission when there is no reply from the group member. Specify a value from 2 to 60. The default is 10 seconds.

  • sig-hash-algorithm—Authentication algorithm used to authenticate the group member to the group server. Specify sha-256 or sha-384.
