Hi,
I would like to know what route should i accept from internet full or partial? if Partial then what routes should i accept? and how many route does my router have if i will go for Partial routing table?
actually I am trying to understand it by concept... my organization is small but I want to know if it is large organization or small provider then what kind of routes do i need in my routing table?
If you don't know, then you should probably ask your upstream to send you a default and leave it at that. Full routes means that you get a routing entry for every network connected to the Internet. There's some two hundred thousand (plus) of them. This can be stressful on both routers and inexperienced administrators, and is probably not all that useful unless you have multiple connections to the Internet. A default gets you just about the same thing. "Partial" doesn't make too much sense, unless you really don't want to talk to certain parts of the Internet, or you're supplementing it with a default route. You could potentially do this if you had, for example, a T1 to two different providers, and wanted some outgoing traffic to go over each link. In that case, most people would prefer to get full tables from each upstream and make local decisions. This requires properly resourcing your router; the "Cidr Report" that is frequently posted here will give you an idea about /current/ requirements in terms of table size, but it is not unreasonable to look for something that can handle 30-50% growth, plus IPv6 concerns. If you've got an existing router that can't hack it, but still need to balance over two connections, that's one scenario for "partial" routes. By definition, partial would be any number between 1 and the current number of available route prefixes, and would be determined by your choice of configurations. There are some really quite excellent books on routing on the Internet available, as well as extensive information in this list's archive. Avi also has some historical documents that are probably still good. Look around http://www.freedman.net/ ...
