I am using 2811 router in 5 locations (say siteA,siteB,siteC,siteD,siteE).
they all are connected through leased line.
i want to know if the leased line fails in 1 location( say in site A) all the other locations (siteB,siteC,siteD,siteE) shoud communication to that location (siteA) through VPN.
And communication beteween siteB to siteC,siteB to siteD,siteB to siteE ,siteC to siteD,siteC to SiteE,siteD to siteE should continue with the existing leased line.
Your help will be highly appreciated.
