Hi,
How Can I do "default route" under router eigrp command. I mean that how can stub router send unkown packet to hub router ?
because stub router connect internet via hub router.
Thank You

OK, so on router A you have a router that looks something like this?
ip route 0.0.0.0 0.0.0.0 10.0.0.1

I know it. But...How Can Router A announce to spokes about Internet. Because spokes connect to internet via hub router

So .. Router A will have to tell EIGRP about its Internet route - in other words redistribution. Why is that a problem?
It would still be dynamic. If 10.0.0.1 disappeared, then so would the default route disappear from the spokes.

The only way it can announce the routes to the spokes is via a routing protocol. If you want to use a routing protocol (EIGRP) you put the 0.0.0.0 0.0.0.0 static route on router A into EIGRP. You do that via redistribution, it's the best way. What the spokes see in their routing table is a 0.0.0.0 0.0.0.0 route pointing to the hub router.

but It is not enough..

What do you mean that not enough?

Router A set default-network and ip route to Internet...But How RouterA send to spokes default route information.Is it enough add redistribute static?

If your hub has a default route to the Internet and it is a static, and you do a redistribute static, then all the spokes will see the default route automatically. That is the way it is done in EIGRP.
If you have any other statics in the hub, then they will get distributed too.
The spoke-to-spoke routes, will get advertised in the normal way through EIGRP.

Yes, I added it. Spoke router see like D*EX 0.0.0.0/0 [170/2195456] via 192.168.1.1, 00:40:20, Serial0.
But Spoke router cant access via hub router to internet.

That is probably something to do with the address translation. The Internet has never heard of the addresses of your spoke routers or anything attached to them. If they are private addresses link in your diagram (192.168.1.0/24, it never will.
So you be translating those addresses into something that the Internet does understand, such as the address of your Internet link. This will be done in your DSL router. Does the DSL router know about 192.168.1.0/24?
Can you supply details of your Network Address Translation scheme so that we can sort it out.

From the spoke network (not the router) can you do a traceroute to an IP on the internet and post the results?

This client of spoke router
[root@root ~]# traceroute 74.125.19.103
traceroute to 74.125.19.103 (74.125.19.103), 30 hops max, 40 byte packets

I solved it :)

Glad to hear its fixed. I looked up that command since I was not familiar with it. What routing protocol are you using for internet connectivity (just curious)?
