EOIP between 6.30.1 and older ROS

Hi all,

after updating CCR from 6.20 to 6.30.1 the EOIP tunnel didn’t come up. Peer is running on 6.20. Keepalive of 10sec ist set on both.

On CCR Keepalive-retry is set to 3 (after update).

Any idear? Keepalive set to 1 will not work. Going back to 6.20 and everything is ok.
