which routes are forwarded by EIGRP router?

Say, a router has routes of O(OSPF), D(EIGRP), and S(static). Which routes will be forwarded by the EIGRP router?

I thought EIGRP should forward routes shown in "show ip route eigrp", which include D and S. However, it turns out S is not included in the output.

It sends whatever you tell it to! You can use a network command to have it send local connected networks participating in EIGRP. For other protocols (OSPF, static) you would need to redistribute them in.

as mod said:redistribute static command or b) using the network 0.0.0.0 command to advertise the default route to internal router(s).

while static might not appear in your sh ip eigrp route ,but think if you ran sh run or sh ip route it would be there.

Jee! For years I thought the command "network [x.x.x.x]" means which network interface the EIGRP will use to fwd routes. Thank you!

The network statement tells the router which interfaces participate in the protocol. Interfaces participating in the protocol send hellos to form neighbors. The protocol also adds the connected prefixes.

In a case we use network statements to add directly connected networks as 192.168.1.0 and 10.1.0.0, and then use passive to disable the network interface of 10.1.0.0. I figure the route to 10.1.0.0 will still be forwarded by the EIGRP router right?

Yes. Passive interface connected networks are still advertised but do not send/receive hellos.
