I am trying to understanding the issue of EIGRP queries and Stuck in Active,<br />
in some articles they say to prevent this to happen you can configure Summarization or Stub router.<br />
in other articles they say Cisco came up with : SIA Query and SIA Reply.<br />
<br />
If I understand we do not even have to type SIA Query and/or SIA Reply on the router, they are ON by default . Correct?<br />
if so, then we do not have to worry about configuring Summarization or Stub router to prevent SIA. correct ?<br />

Thank you

EIGRP Queries and Stuck in Active

A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.

A switch is a device that filters and forwards packets of data between LAN segments. Switches operate at the data link layer or the network layer of the Open Systems Interconnection (OSI) Reference Model and therefore support any packet protocol. LANs that use switches to join segments are called switched LANs or, in the case of Ethernet networks, switched Ethernet LANs. A hub is a connection point for devices in a network. Hubs are commonly used to connect segments of a LAN. A hub contains multiple ports; when a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.
