Comment 4 for bug 1570122

I've a deployment with IPv6 and this is very annoying because periodically the rules are refreshed (it seems like is this) and the manually inserted rules are removed.

I'm using a crontab script to check each qrouter and apply the rule manually.

---
#!/bin/bash

for qrouter in `ip netns | grep ^qrouter`; do
        interface_qg=`ip netns exec $qrouter ifconfig | grep ^qg | awk '{print $1}'`

        qtd_mark=`ip netns exec $qrouter ip6tables -n -L -v -t mangle | grep "MARK xset" | wc -l`
        if [ $qtd_mark -lt 2 ]; then
                echo "APLICAR ==> /bin/ip netns exec $qrouter ip6tables -t mangle -A neutron-l3-agent-scope -i $interface_qg -j MARK --set-xmark 0x4000000/0xffff0000"
                /bin/ip netns exec $qrouter ip6tables -t mangle -A neutron-l3-agent-scope -i $interface_qg -j MARK --set-xmark 0x4000000/0xffff0000
        else
                echo -e "[OK] Regra ip6tables"
        fi
done
