Refer to the exhibit.
 
Network administrators have set up a hub and spoke topology with redundant connections using EIGRP. However, they are concerned that a network outage between Router R1 and Router R2 will cause traffic from the 10.1.1.x network to the 10.1.2.x network to traverse the remote office links and overwhelm them.
What command should be used to configure the spoke routers as EIGRP stub routers that will not advertise connected networks, static routes, or summary addresses?

A. eigrp stub

B. eigrp stub receive-only

C. eigrp stub connected static

D. no eigrp stub connected static








 

Suggested Answer: E. No additional command is needed beyond a default EIGRP configuration.

A router that is configured as a stub with the eigrp stub command shares connected and summary routing information with all neighbor routers by default. Four optional keywords can be used with the eigrp stub command to modify this behavior:
receive-only
 
connected
 
static
 
summary
 
This section provides configuration examples for all forms of the eigrp stub command. The eigrp stub command can be modified with several options, and these options can be used in any combination except for the receive-only keyword. The receive-only keyword will restrict the router from sharing any of its routes with any other router in that EIGRP autonomous system, and the receive-only keyword will not permit any other option to be specified because it prevents any type of route from being sent. The three other optional keywords (connected, static, and summary) can be used in any combination but cannot be used with the receive- only keyword. If any of these three keywords is used individually with the eigrp stub command, connected and summary routes will not be sent automatically.
The connected keyword will permit the EIGRP Stub Routing feature to send connected routes. If the connected routes are not covered by a network statement, it may be necessary to redistribute connected routes with the redistribute connected command under the EIGRP process. This option is enabled by default.
The static keyword will permit the EIGRP Stub Routing feature to send static routes. Without the configuration of this option, EIGRP will not send any static routes, including internal static routes that normally would be automatically redistributed. It will still be necessary to redistribute static routes with the redistribute static command.
The summary keyword will permit the EIGRP Stub Routing feature to send summary routes. Summary routes can be created manually with the summary address command or automatically at a major network border router with the auto-summary command enabled.
This option is enabled by default.
In the following example, the eigrp stub command is used to configure the router as a stub that advertises connected and summary routes: router eigrp 1 network 10.0.0.0 eigrp stub
In the following example, the eigrp stub command is issued with the connected and static keywords to configure the router as a stub that advertises connected and static routes (sending summary routes will not be permitted): router eigrp 1 network 10.0.0.0 eigrp stub connected static
In the following example, the eigrp stub command is issued with the receive-only keyword to configure the router as a receive-only neighbor (Connected, summary, and static routes will not be sent): router eigrp 1 network 10.0.0.0 eigrp eigrp stub receive-only
