I want to setup 2 dns server in my network
both of them will have identical setup and same zone file.
Do you want to serve for "internal" domains, i.e. not publically visible domains? Or are these domain servers for an internet visible domain? Then the root nameservers [whois record] comes into play as Suresh mentioned. Or are these NS only for resolving external/internet domains, i.e. caching/forwarding servers?
In case of the first two cases, suggest setting up one as the primary and the other as a secondary so that zone updates are automatically mirrored.
My object is that if one server goes down other server should serve the queries.
From this, I sense that you want some sort of high-availability/clustering/failover like, say, Windows NLB.
DNS does not [need to] work that way...most commonly, you configure multiple DNS servers on the client side and the client takes care of looking up one server if another is not available.
If you [shudder] indeed want "clustering/failover", then look at something like http://www.linuxvirtualserver.org
I want to use bind as the name server
Regardless of what anyone says, I would suggest BIND...pleas for DJBDNS are, well, crap.
Pls. help me regarding this.
DNS, though taken for granted a lot of times, has a lot of subtle issues related with it and can give you a lot of headache as an admin, if not done right.
Without any mailce, I suspect that you need quite a lot of information about the basics. Recommend "DNS and BIND" by Albitz and Liu [O'Reilly - The Grasshoper Book]. Covers basics very well, right through to medium and semi-advanced topics.
