In order to maintain security, with which hop count are IPv6 neighbor discovery packets sent?

A.    0
B.    1
C.    255
D.    256

Answer: C

Which command will define a VRF with name ‘CCIE’ in IPv6?

A.    ip vrf CCIE
B.    ipv6 vrf CCIE
C.    vrf definition CCIE
D.    ipv6 vrf definition CCIE

Answer: C
Vrf definition CCIE creates a multiprotocol VRF for both IPv4 and IPv6

For which routes does LDP advertise a label binding?

A.    all routes in the routing table
B.    only the IGP and BGP routes in the routing table
C.    only the BGP routes in the routing table
D.    only the IGP routes in the routing table

Answer: D
LDP can only do bindings for IGP learned routes. If the route is learned from BGP, BGP has to do the label binding. For CCIE R&S you don’t need to worry about using BGP for label distribution, as this is used for Inter-AS MPLS L3VPN scenarios. If you change your setup so the routes are learned from IGP instead of BGP they will have labels.

Which command can be used on a PE router to connect to a CE router ( in VRF red?

A.    telnet /vrf-source red
B.    telnet source /vrf red
C.    telnet /source vrf red
D.    telnet /vrf red
E.    telnet vrf red

Answer: D
Telnetting can be done through the VRF using the Management Ethernet interface. In the following example, the router telnets to through the Management Ethernet interface VRF:
Router# telnet /vrf Mgmt-intf

Which two statements are correct about Nonstop Forwarding? (Choose two.)

A.    It allows the standby RP to take control of the device after a hardware or software fault on the active RP.
B.    It is a Layer 3 function that works with SSO to minimize the amount of time a network is
unavailable to users following a switchover.
C.    It is supported by the implementation of EIGRP, OSPF, RIPv2, and BGP protocols.
D.    It synchronizes startup configuration, startup variables, and running configuration.
E.    The main objective of NSF is to continue forwarding IP packets following a switchover.
F.    Layer 2 802.1w or 802.1s must be used, as 802.1d cannot process the Layer 2 changes.
G.    Routing protocol tuning parameters must be the same as the NSF parameters, or failover will
be inconsistent.

Answer: BE
Cisco Nonstop Forwarding (NSF) works with the Stateful Switchover (SSO) feature in Cisco IOS software. NSF works with SSO to minimize the amount of time a network is unavailable to its users following a switchover. The main objective of Cisco NSF is to continue forwarding IP packets following a Route Processor (RP) switchover.

Which three fields are optional in an OSPFv3 external LSA? (Choose three.)

A.    Forwarding Address
B.    External Route
C.    Reference Link-State ID
D.    Option
E.    Prefix Options

Answer: ABC
AS-External LSA
As with OSPFv2, the AS-External LSA advertises prefixes external to the OSPF routing domain; one LSA is required for each external prefix advertised. However, the format of the OSPFv3 As-External LSA (Figure 9-10) is different from its OSPFv2 counterpart.

On a router, interface S0 is running EIGRPv6, and interface S1 is running OSPFv3. A
redistribution command is issued under OSPFv3, redistribute EIGRP 1 metric 20 under ipv6 router nospf 1. What will happen after applying this redistribution command?

A.    All routes showing up as D and D EX in the routing table will be redistributed into OSPFv3.
B.    All routes showing up as D, D EX, and C in the routing table will be redistributed into OSPFv3.
C.    All routes showing up as D and D EX in the routing table and the S0 interface will be
redistributed into OSPFv3.
D.    All routes showing up as D in the routing table will be redistributed into OSPFv3.
E.    All routes showing up as D EX in the routing table will be redistributed into OSPFv3.

Answer: A
D are EIGRP Internal Routes and D EX are EIGRP external routes. Both Internal and External EIGRP routes will be redistributed with the configuration shown above

Which type of domains is interconnected using Multicast Source Discovery Protocol?

A.    PIM-SM
B.    PIM-DM

Answer: A
Multicast Source Discovery Protocol (MSDP) is a Protocol Independent Multicast (PIM) family multicast routing protocol defined by Experimental RFC 3618. MSDP interconnects multiple IPv4 PIM Sparse-Mode (PIM-SM) domains which enables PIM-SM to have Rendezvous Point (RP) redundancy and inter-domain multicasting.

Which two multicast address ranges are assigned as source-specific multicast destination
addresses and are reserved for use by source-specific applications and protocols? (Choose two.)

D.    FF3x::/32
E.    FF2x::/32
F.    FF3x::/16

Answer: AD
Source-specific multicast (SSM) is a method of delivering multicast packets in which the only packets that are delivered to a receiver are those originating from a specific source address requested by the receiver. By so limiting the source, SSM reduces demands on the network and improves security. SSM requires that the receiver specify the source address and explicitly excludes the use of the (*, G) join for all multicast groups in RFC 3376, which is possible only in IPv4’s IGMPv3 and IPv6’s MLDv2. Source-specific multicast is best understood in contrast to any-source multicast (ASM). In the ASM service model a receiver expresses interest in traffic to a multicast address. The multicast network must
1. discover all multicast sources sending to that address, and
2. route data from all sources to all interested receivers. This behavior is particularly well suited to groupware applications where
1. all participants in the group want to be aware of all other participants, and
2. the list of participants is not known in advance.
The source discovery burden on the network can become significant when the number of sources is large.
In the SSM service model, in addition to the receiver expressing interest in traffic to a multicast address, the receiver expresses interest in receiving traffic from only one specific source sending to that multicast address.
This relieves the network of discovering many multicast sources and reduces the amount of multicast routing information that the network must maintain. SSM requires support in last-hop routers and in the receiver’s operating system. SSM support is not required in other network components, including routers and even the sending host. Interest in multicast traffic from a specific source is conveyed from hosts to routers using IGMPv3 as specified in RFC 4607.
SSM destination addresses must be in the ranges for IPv4 or FF3x::/96 for IPv6.

How is RPF used in multicast routing?

A.    to prevent multicast packets from looping
B.    to prevent PIM packets from looping
C.    to instruct PIM where to send a (*,G) or (S,G) join message
D.    to prevent multicast packets from looping and to instruct PIM where to send a (*,G) or (S,G) join message
