L2TP - old tunnel is not closed

bedior · October 29, 2018, 5:21am

Hello!
I am working on failover script and found, that after change route distance of my ISP and disable/enable lt2p connection, my l2tp connect much longer. In log I found rows:

But, when I disable/enable lt2p connection without change routes, it connect much faster:

Why it happens and what mean “old tunnel is not closed”? Can I close it from script?

temporal solution:
ppp - profiles - limits - only one => NO

This is BUG. Router don’t close old connection…
