To configure 6to4 on a dual-stack edge router. Which three of the following are valid in 6to4
Tunneling configuration? (Choose three)

A network administrator is troubleshooting a redistribution of OSPF routes into EIGRP.
router eigrp 1
network 10.0.0.0
!
router ospf 1
network 172.10.0.0 0.0.255.255 area 0
redistribute eigrp 1
Given the exhibited commands, which statement is true?

Which three steps are most helpful in verifying proper route redistribution? (Choose three.)

A router is configured for redistribution to advertise EIGRP routes into OSPF on a boundary router.
Given the configuration:
router ospf 1
redistribute eigrp 1 metric 25 subnets
What is the function of the 25 parameter in the redistribute command?

Refer to the exhibit.

R1 and R2 belong to the RIP routing domain that includes the networks 10.20.0.0/16 and
10.21.0.0/16. R3 and R4 are performing two-way route redistribution between OSPF and RIP. A

network administrator has discovered that R2 is receiving OSPF routes for the networks
10.20.0.0/16 and 10.21.0.0/16 and a routing loop has occurred.
Which action will correct this problem?

Observe the exhibit.

If the command variance 3 were added to RTE, which path or paths would be chosen to route
traffic to network X?

Which command should be added to RTB under router bgp 100 to allow only the external OSPF
routes to be redistributed to RTC?

Router E is configured with the EIGRP variance 2 command.

What path will Router E take to reach Router A?

A network administrator recently redistributed RIP routes into an OSPF domain. However, the
administrator wants to configure the network so that instead of 32 external type-5 LSAs flooding
into the OSPF network, there is only one.

What must the administrator do to accomplish this?

Refer to the exhibit.

If R1 is configured for 6to4 tunneling, what will the prefix of its IPv6 network be?
