hi we have main data center included two 6509 core switches with FWMW and IPS,
We want to implement new DR site where we will include 6509 also with the same modules, i do not know how we can architect this new DR and what is required link between the two site main and DR from links and other and how we can achieve the required redundancy in case of main data center failes,appreciate your feedback also if there is any document provide details for such interconnectivity between the main data center and the DR.
the distance between the two site is less than 15 Kilo Meters,and there is fiber between the two sites, so what is the best way to interconnect here because no long distance here and what is the best way in this distance to extend the L2 VLAN extension between the two sites.
