I m running with a smooth enterprise network,IT Manager is planning for Disaster recovery for the enterprise on another location.How can i setup the failover of internal enterprise application to the DR site from network point of view, IT manager is planning for MPLS link to DR site.
If I have well understood your needs and depending on your architecture I am thinking to GSS (Global Site Selector), which allows (along with other functions like GSLB) disaster recovery between different sites working with local SLB devices (like ACE, CSS ...).
Introducing the Global Site Selector (http://www.ciscopress.info/en/US/docs/app_ntwk_services/data_center_app_services/gss4400series/v3.1.1/configuration/cli/gslb/guide/Intro.html#wp1097368)
Organizations with a global reach or businesses that provide web and application hosting services require network devices that can perform complex request routing to two or more redundant, geographically dispersed data centers. These network devices need to provide fast response times and disaster recovery and failover protection through global server load balancing, or GSLB.
