What is the advantage of BGP confederation implementation compared to BGP route reflector implementation?
A service provider is in the process of providing Layer 2 and Layer 3 VPN services through a MPLS LDP-enabled backbone. With load increasing in the service provider domain, scalability become the most important. Based on the local label allocation filtering feature, which is the lower subset of prefixes must be selected to meet these requirements?
A service provider offers four classes of service for MPLS VPN customer with the following IPP/EXP values: i. voice = 5 ii. video = 4 iii. priority data = 3 iv. best-effort data = 0The service-provider also supports multicast VPN services in the priority data and best-effort classes. Multicast VPN is implemented as a draft-rosen profile. On aP router, in the MPLS core, the ingress QoS policy-map must classify all incoming packets, so that different classes of traffic can be property handled in fabric queues and egress queues. All types of packets in the core network must be covered.Which ingress classification offers the optimal performance and provides the minimum number of actions that match the service provider QoS requirements?
A Layer 3 VPN customer opened a case that reports connectivity loss with remote sites. An operations engineer realized this connectivity loss happened after theLDP label filtering was applied. What is the root cause of this issue?
Refer to the exhibit. The P1 router is elected as the DIS on the broadcast link. Assuming that all the configurations are applied correctly, how many routers will establish IS-IS neighborship with P1 router on this broadcast link?
Which Cisco IOS XR Virtualization technology provides full isolation between virtualized routing instances for extra control plane resources?
