Hi all,

I wonder if a secondary gateway can be configured in AIX, so in case the default gateway goes down the server remain accessible.

Thanks in advance & best regards.

Hi

Yes, AIX5L can be configured to use Dead Gateway Detection

Hope this helps

I read the document but I can't figure out where & how to specify the secondary gateway address. The Dead Gateway Detection service can detect it automatically?

Please take a look of the following links:

http://www.redbooks.ibm.com/redpapers/pdfs/redp0103.pdf

You will have to use a combination of mktcpip command when configuring the TCPIP address and default gateway for the intended interface with the route command to add the aditional route with the -active_dgd option in order for the TCPIP to monitor (in either active or passive way) the default gateway and start using the intended gateway.

Hope this helps
