GSLB design issue

[syjeon]

Hi.

our company with to make a DR center.

So we are checking the cisco solution,GSS

My question is like below

if there are Active DR and Backup DR

In two DR center, there must be two

PrimaryNS server for delegation to gss?

In my thought, the GSS cound be a Primary NS for dns requesting from .com dns server.

Is it a possible topology?

You can do DR Site with OSPF.At site 1, the 2 internet links are of unequal capacity & diference in BW is also more. If u do load-balancing, 1Mbps may be choked throughout the day whereas 5Mbps may not have much on it. It is better to use the 2 links in active /backup configuration using either static routes with AD in case of single ISP, or BGP if multihoming.
