An engineer uses 2 routers to test Pv6 services and runs OSPFV3 to achieve interconnection and interoperability of IPV6 networks The RI has access to the loopback address of R2 The engineer looks at ri's OSPF3 routing table entry and finds that there is no route reaching the R2 loopback address It can't be caused by which of the following?

R2 does not enable OSPFv3 on the loopback port

R2 does not advertise the loopback address

R2 in area 0 to advertise the loopback into a different OSPFv3 process

R2 does not configure the Router ID used in the OSPFv3 process

Question 555

The following statement about the concept of multicast is wrong?

Multicast Source: The sender of the message needs to join the multicast group to provide forwarding of multicast group messages

Multicast router: A router or layer-three switch that supports layer-3 multicast functionality

Multicast Group Members: Multicast group members can be widely distributed anywhere in the network

Multicast Groups: A collection identified by ip multicast addresses

Question 558

About multi-instance CE (Multi-VPN-Instance CE, MCE). What is the error described below?

Users who connect to the same MCE but are not part of a VPN instance cannot access each other

The MCE vs. PE direction must have multiple physical links to achieve isolation between different VPN instances

MCE-enabled devices can access multiple VPI instances in BGP/RPLS IPVPN applications, reducing user network equipment investment

On the MCE device, you need to create their own routing tables for different VPNs and bind to the corresponding interface
