There is no reason for a disaster recovery site to use bridging instead of routing. The real problem is: "If I bring down the main site, how and by which addresses the branch sites and other offices will connect ?".
Bridging in itself does't offer a solution to this problem.
Unfortunately, there is no easy answer. each application, vendor, integrator can propose a different solution and I have yet to see one that is totally satisfying. Then it depends by the customer. Some are happy just having an almost ready copy of all-data, other pretend small switching times.
Designing something that works for real (not on paper only) can be difficult, expensive and time-consuming.
