1 subnet split over 2 locations?

Answered Question

Hi we have a subnet which for clustering purposes must be split across 2 different locations connected via a leased line.


At the moment we are spanning 1 vlan across the two switches at either end via a trunk.


However if we lose the trunk connection we can still reach the remote site via layer 3 access (as the site has more than one connection) but the trunk goes down along with the link therefore full connectivity is lost.


Can anyone suggest a better way to split one subnet across the two sites? We cannot put another connection in and we cannot use a trunk via the other l3 links either as this would mean a major reconfuguration of the current set ups.


Any help would be great


thanks

As far as i know unfortuntely not, at least i haven't come across it before. It might be worth checking the Pix release notes just in case.


Edit - bear in mind that it is using tunneling so there is no reason why you couldn't use 2 routers and tunnel through the pix firewalls but that depends on your security policy really.
