select two options from the below list that are supported.

Though many options are supported in EIGRPv6, select two options from the below list that are
supported. Choose 2

A.
VRF

B.
auto-summary

C.
per-interface configuration

D.
prefix-list support via route-map

E.
prefix-list support via distribute-list

Explanation:
EIGRPv6 does differ from EIGRPv4 in the following ways:
EIGRPv6 is configured (enabled) directly on Cisco routers interfaces; this means EIGRPv6 can be
configured (enabled) on a routers interface, without having to configure (assign) a Global IPv6
address on the interface and without using the network command while the router is in router
configuration mode.
Also, when configuring (enabling) EIGRPv6 on a Cisco router, the EIGRP routing process must be
configured (assigned) with a router-id (by using the router configuration command router-id); if a
router-id is not configured (assigned) the EIGRPv6 routing process will not start.
The EIGRPv6 routing process also uses a shutdown feature; meaning an EIGRPv6 routing
process will not start until the routing process has been placed into no shutdown mode. (by, typing

the no shutdown command while the router is in router configuration mode)
Also, on Passive Interfaces; EIGRPv6 is not required to be configured.
Lastly, EIGRPv6 use the router configuration command distribute-list prefix-list to perform route
filtering; and when configuring route filtering the route-map command is not supported.
Below is some additional information on EIGRPv6:
IPv6 EIGRP and IPV4 EIGRP are very similar in concept except for the following differences:
IPv6 is configured on interface basis (like OSPFv3 and RIPng) and networks are advertised based
on the interface command -> C is correct.
When configured on interface, IPv6 EIGRP is initially placed in “shutdown” state as with OSPFv3,
IPv6 EIGRP require a router-id in IPv4 format Passive interfaces can only be configured in the
routing process mode. The need for extra memory resources and supported in IOS 12.4(6)T and
later.
There is no split horizon in IPv6 because it is possible to get multiple prefixes per interface. Their
is no concept of classful routing in IPv6 EIGRP consequently no automatic summary -> B is not
correct EIGRPv6 uses the router configuration command “distribute-list prefix-list” to perform route
filtering, and when configuring route filtering the “route-map” command is not supported -> E is
correct but D is not.
Virtual Routing and Forwarding (VRF) is also supported in EIGRPv6.
