Re: Gateway shut down detection takes too time from other nodes

[Simon Wunderlich <sw@simonwunderlich.de>]

Hi,

can you describe your setup a bit more? Are your "gateways" connected with 
each other over Ethernet? Do you have multiple DHCP servers on your gateways 
respectively, or is there a DHCP server in your LAN interconnecting gateways? 
Are you using bridge loop avoidance? Perhaps an illustration would help.

There are different scenarios how to set up this network kind of network, and 
failover time  may differ from a couple of seconds to a couple of minutes 
depending on the setup.

Thank you,
        Simon
