Nice article:

Removing SA for tunnel:

let's have a look what is in the SAD in a "raw" manner

echo S > /var/run/isakmpd.fifo
less /var/run/isakmpd.result

Look for SA name for phase 1 and 2

Remove phase 2 and 1 using these names:

echo 't quick VPN-IB-BAN-NET' > /var/run/isakmpd.fifo
echo 't main bangalore' > /var/run/isakmpd.fifo

Reread configuration file and update tunnel

echo 'R' > /var/run/isakmpd.fifo

check running config

echo 'r' > /var/run/isakmpd.fifo
grep isa /var/log/messages
