第12题:
OSPF over multicast EMS or VPLS network may not have consistent broadcast or multicastperformance
IP multicast is not supported over Lover 3 MPLS VPN; instead a Layer 2 MPLS WN must beutilized with service provider support
QoS requirements with MPLS-VPN must be implemented by the service provider
Hierarchical VPLS designs are the least scalable
IGMP snooping is not on option with VPLS or EMS; instead administrative scoping or allowingsufficient bandwidth for unnecessary multicast traffic at the edge links is required

第20题:
VPLS业务数据转发需要查询MAC地址转发表,PWE3业务转发不需要查询MAC地址转发表
创建VPLS业务时,所有业务接入接口的VLAN可以配置成一样,但PWE3的两个业务接口需要配置不同的VLAN
VPLS业务如果配置不当,会有环路风险,PWE3业务不会导致环路

第21题:
Neither broadcast nor multicast traffic is ever flooded in VPLS.
Multicast traffic is flooded but broadcast traffic is not flooded in VPLS.
VPLS emulates an Ethernet switch, with eachEMS being analogous to a VLAN.
Because U-PE devices act as IEEE 802.1 devices, the VPLS core must use STP.
When the provider experiences an outage, IP re-routing restores PW connectivity and MAC relearning is needed.
