EIGRP supports both MD5 and SHA hashing authentication. Support for SHA was introduced in Cisco IOS 15 releases, together with the named EIGRP configuration mode.
default route can be created with the ip default-network command.
A router that is configured with this command considers the network listed in the command as the last-resort gateway and it will announce it to other routers.
The network specified by this command must be reachable by the router upon which the command is issued before it announces it as a candidate default route to other EIGRP routers.
The network specified by this command must also be passed to other EIGRP routers so that those routers can use this network as their default network and set it as the gateway of last resort. This means that either the network must be an EIGRP-derived network in the routing table or it must be generated using a static route that has been redistributed into EIGRP.
The default-information originate command is used to generate a default external route into an OSPF routing domain. It is not used to configure an EIGRP default route.
The ip route 0.0.0.0 0.0.0.0 next-hop command is used to statically configure a default route in the routing table.
This route can be used as the default route for EIGRP using the ip default-network command.
However, it must also be advertised by EIGRP using the redistribute static command.
The auto-summary command is used to turn on EIGRP automatic summarization. Automatic summarization is on by default. You can disable it using the no auto-summary command.
EIGRP can redistribute statically defined default routes by using the redistribute static configuration command. The redistribute static command redistributes all statically (manually) defined routes into the EIGRP process. Since a default route has been manually defined, this route will be redistributed into EIGRP and advertised to its neighbors.
The connected option permits the EIGRP stub router to advertise all connected routes for interfaces that are matched with an EIGRP network command. This option is enabled by default and is the most widely practiced stub option. The eigrp stub connected command can be used to enable the connected option, if it is disabled. It is not used to allow a manually configured default route to be advertised by EIGRP.
The default-information originate command can be used to generate a default external route into an OSPF routing domain. The default-information originate command, when used with RIPng, announces the default route to the neighboring routers even if there is no local default route present in the routing table. The default-information originate command is not used to allow a manually configured default route to be advertised by EIGRP.
The receive-only option restricts the stub router from sharing any of its routes with any other router within an EIGRP AS. This option does not permit any other option to be specified, because it prevents any type of route from being sent. The eigrp stub receive-only command is not used to allow a manually configured default route to be advertised by EIGRP.

B. Uses Multicast
C. Automatic summarization is not possible
Which two of the following are used in EIGRP metric calculations by default? (Choose two)
