No MD5 digest from <source ipv6>+<port no.> to <destination ipv6>+<port no.> [VRF <vrf id>]

Warning (remote device)

The MD5 authentication option is not set for the TCP segment received by BGP4+ connection.

This operation message is output according to the following conditions:

  1. The messages from the first to the 16th event are output.

  2. After 17 times from the beginning of the event occurrence, this message is output once every 256 times the event occurs.

  3. If an event occurs 3 minutes or more after the last event occurred, this message is output when 1 or 2 above occurs.
