Hi all,
I am trying to come up with an architecture that has some redundancy. The idea is to hook up the two GbE LAN interfaces of a CentOS server to two Gigabit Ethernet switches. In case one switch goes down, there is a redundant path (the server is redundant too). Here is the idea:
----------- | GbE |PCs ------------| switch |------------ | | ----------- | | ----------------- ----------------- ---| Workgoup Switch | | CentOS/Asterisk | | ----------------- ----------------- | | ----------- | VoIP ------------| GbE |------------ Phones | switch | -----------
Why don't you just bond the two interfaces? An alternative would be to use one interface as a primary link and periodically check its "hearbeat". If the interface goes down, you just add the route for the other interface to your default gateway. Bonding the 2 channels is probably the easier method, though.
