LAN Disaster Recovery Planning

Does anyone have any experience of disaster recovery planning for LANs?

Any suggestions/advice on what should be included, what to think about etc?

Or any useful URLs on this subject?

Thanks.

Re: LAN Disaster Recovery Planning

Wow, that is a pretty open ended topic. There are almost as many design considerations as there are LANs... well, not quite. Is there one particular LAN installation that you wish to address or is this more of a "best practice" topic?

Some of the DR concepts depend on the infrastructure that is or will be in place.
Is the LAN flat or segmented? VLANs? core/edge switches? layer2 or 3? mesh? trunks? STP?

Then there are physical site considerations. Building separation for natural or man made disasters, power fail, fire, earthquake, tornado, 9/11, etc.

This all then factors on what is the need driving High Availability and what the worst case recovery time has to be.

Hi Les,

yes, really just looking for best practise type information at this stage: examples of what should be included, examples of what to take into consideration, etc - rather than any specific "nitty-gritty" details, at this stage.

If anyone has any useful resources on this kind of thing, eg helpful URLs, recommended books, etc then that would also be appreciated.

Thanks,

Neil

Loads of things to think about - it all depends on your needs.

I've enjoyed reading "High Availability Networking with Cisco" by Vincent C. Jones. It covers some of the topics - but the intended audience is people with hands-on. Great if you know something about configuring boxes, routing protocols etc., otherwise quite boring - loads of sample configurations

Take a look at <> and see if it fits your needs.
