CSS VIPs Redundancy falls over for few seconds every week

Question: Can I change the Max Failures of the Keep alive AUTO_nexthop00001?

We have CSS in Redundant VIP setup.

We using on Active CSS an Critical Server script ap-kal-pinglist name is up_downstream

It seems that the active CSS stops working almost every week now for a few seconds.

So the Next hop auto generated keep alive of de default gateway is down

This triggered the Critical server script up_downstream and the BOX False over.

Sound all very normal but the IP number 10.1.114.1 is available.

Gilles Dufour · ‎05-06-2005

instead of using a script to monitor nexthop0001, why don't you create a service with icmp keepalive so you can control yourself frequency and max failures.

There is no way to change the auto_nexthop00001 max failures.

did not suspect the auto_nexthop00001 will automaticly removed, if I create a keepalive services myself.

Thanks a lot!

Gilles Dufour · ‎05-06-2005

actually, the CSS will keep the auto_nexthop0001.

If you want to get rid of it, you need the command "ip no-implicit-service" and then reboot.
