質問 # 73
What is a restriction of 6PE?
- A. It adds a value of ::FFFE: on the IPv4 next hop address.
- B. It cannot be implemented on VRFs.
- C. It is implemented only over eBGP peers.
- D. It is implemented only over iBGP peers.
正解：B
解説：
6PE (IPv6 Provider Edge) is a method to enable IPv6 traffic over an MPLS IPv4-only core without the need to upgrade the core to support IPv6. In 6PE, the IPv6 prefixes are transported using BGP over an MPLS backbone. The IPv6 traffic is encapsulated with an IPv4 MPLS label and forwarded across the network.
6PE cannot be implemented on VRFs because it operates within the global routing table and does not utilize VRF-based services like those in 6VPE (IPv6 VPN Provider Edge). 6VPE, on the other hand, supports VRFs and enables IPv6 VPN services over an MPLS IPv4 core.
質問 # 74
A network engineer is troubleshooting OSPF multiare A.
Which Cisco IOS XR feature should the engineer use in order to streamline OSPF issue?
- A. routing process enabled by default on all interfaces
- B. DR support for topology management
- C. show ip ospf topology command
- D. hierarchical CLI
正解：D
解説：
OSPF Hierarchical CLI and CLI Inheritance
Hierarchical CLI is the grouping of related network component information at defined hierarchical levels such as at the router, area, and interface levels.
Hierarchical CLI allows for easier configuration, maintenance, and troubleshooting of OSPF configurations.
When configuration commands are displayed together in their hierarchical context, visual inspections are simplified. Hierarchical CLI is intrinsic for CLI inheritance to be supported.
With CLI inheritance support, you need not explicitly configure a parameter for an area or interface. In the software, the parameters of interfaces in the same area can be exclusively configured with a single command, or parameter values can be inherited from a higher hierarchical level-such as from the area configuration level or the router ospf configuration levels.

- A. If a router received an iBGP route with the originator-ID attribute set to its own router ID, the route is discarded.
- B. If a route reflector receives a route with a cluster-list attribute containing a different cluster ID, the route is discarded.
- C. Routes received from nonclient peers are reflected to route reflector cluster as well as OSPF peers.
- D. Routes received from nonclient peers are reflected to route reflector clients as well as nonclient peers.
- E. Routes received from a route reflector client is reflected to other clients and nonclient peers.
