Can netwrok run static route and dynamic route the same time?

Question

+----RouterD1 (eigrp)Internet--------RourterA ---RouterB---------RouterC--------- RouterD2(eigrp)                (eigrp)      (static)       (static )+-----RouterD3 (eigrp)In this scenario, we had already setup all the routers to run Eigrp.but now, betweenB and C, we have to use the static route, so here's thequestion, is that possbile to set the static route in the RouterB andRouterC and let rest routers still are still running Eigrp? especillayin RouterD1/D2/D3?if we can still keep the Eigrp running, then what should we do in therouterB/C, or should we need to change the route in the RouterD1/D2/D3?any help wil appriciate.Scott Tetter

Yes. You can run as many routing mechanisms as you wish. Each routing mechanism is assigned an administrative distance, so that if multiple mechanisms have routes to the same destination it will know which one is preferred.

If you put "redistribute static" in B and C's EIGRP configuration, the static routes will be advertised to all the EIGRP neighbors.

-----------------------but I wonder if 'redistribute is used, then could RouterD1/D2/D3 usethe same AS as router A?A consultant told me the Eigrp will termiate in the Router B and RouterC since 2 routers run the static routing, so router A and router Dswill run within different AS, or even they are with same AS, but theserouters cannot learn the routing table from each others. is that right?thanks for your help.Bruce

It doesn't really matter. AS numbers in EIGRP are only relevant when there's some overlap between the routers in the two ASes, so that those routers can configure the appropriate settings for each group. Since the two ASes are disjoint, the AS numbers can be arbitrary, and it doesn't matter if they're the same or not.
