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
E.
No additional command is needed beyond a default EIGRP configuration.
Explanation:
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: receive-only, connected,
static and summary in any combinations except 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 options to be specified
because it prevents any type of route to be sent.
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 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 addresscommand or automatically at a major network borderwith
the auto-summary commandenebled. This option is enabled by default.
