Which statements correctly describe the MVPN route types used in the MVPN over BIERv6 solution?
Select all that apply.
Answer: C,D
Explanation:
Huawei Reference Verification:
Huawei's MVPN over BIERv6 control plane uses BGP MVPN route types for VPN membership and tunnel advertisement. Any MVPN-enabled sender or receiver PE may originate an Intra-AS I-PMSI A-D route advertising membership and the inclusive provider tunnel. These routes discover other MVPN participants and their transport information. S-PMSI A-D routes are originated by sender PEs to announce selective tunnels for specific multicast flows. Customer PIM (C-S,C-G) Join or Prune signaling is represented by the corresponding C-multicast route rather than being automatically converted into a Leaf A-D route. Thus B and C are correct.
Technical Deep Dive:
B and C are correct. BGP MVPN distinguishes inclusive and selective multicast distribution. Intra-AS I-PMSI A-D routes advertise VPN multicast membership and I-PMSI transport information; both sender and receiver PEs can originate them. C-multicast routing information describes receiver interest in individual customer multicast flows. A sender PE may advertise S-PMSI A-D information when selective transport for a particular flow is needed. A Leaf A-D route has a separate function, notably associated with tracking leaves for certain selective tunnel procedures, rather than being the direct translation of every customer PIM Join or Prune.
BIERv6 then uses bit-based forwarding to replicate service packets across the provider underlay without requiring conventional multicast state per flow on every P router. This control/data-plane separation supports large IPTV and enterprise multicast VPN deployments.

NEW QUESTION # 60
Which of the following statements is not correct regarding the traditional metro network architecture?
Answer: A
Explanation:
Huawei Reference Verification:
Huawei carrier architectures distinguish subscriber service-edge functions, network transport, and backbone routing. Broadband gateways commonly supply subscriber service management, SRs provide VPN and business connectivity, OLTs aggregate optical subscribers, and CRs provide backbone connectivity. The logical routing design is independent of the physical interconnection design: simply connecting MSEs and SRs to a municipal CR does not determine that all three must belong to one AS. BGP autonomous-system membership is an operator-specific logical design choice. Consequently the common-AS assertion in C is inconsistent with the intended traditional metro-network diagram, though a shared AS could be a legitimate design in another topology.
Technical Deep Dive:
C is the intended incorrect statement. An MSE ordinarily provides HSI, VoIP, IPTV and subscriber management. The SR is a service-routing aggregation node commonly serving enterprise VPN connectivity; the CR aggregates and transports metro traffic toward the backbone; the OLT aggregates PON subscribers and uplinks to an MSE or suitable routing equipment. 4G backhaul and fixed services can share physical transport when traffic isolation, bandwidth engineering, and QoS are properly designed. What makes C problematic is treating a same-AS relationship as an intrinsic consequence of the MSE/SR/CR topology.
Devices connected by physical or logical links can exchange routes through EBGP across distinct autonomous systems, or they may use IBGP and an IGP within one AS. This question assumes a particular Huawei metro- AS deployment. Under that assumed deployment C is incorrect; outside it, the statement is not universally impossible. The architectural premise is essential to a rigorous interpretation.

NEW QUESTION # 61
Which vBRAS communication channel is used to carry forwarding-control data sent from the vBRAS-CP to the vBRAS-UP?
Answer: B
Explanation:
Huawei Reference Verification:
Huawei's CUPS design separates communication interfaces between vBRAS-CP and vBRAS-UP into protocol, control, and management functions. The control channel sends subscriber service and forwarding entries from the control-plane system to the user-plane device and supports user-plane event reporting.
Subscriber access signaling, such as PPPoE and IPoE messages requiring central processing, uses the protocol channel. Management operations and configuration queries use management-plane interfaces and protocols such as NETCONF. Once authentication succeeds, the CP distributes the forwarding rules needed for the UP to process traffic. The channel transporting those forwarding-control entries is the control channel.
Technical Deep Dive:
D is correct because the control channel exists specifically to program the distributed forwarding plane. The vBRAS-CP coordinates user sessions, authentication, address allocation, accounting, policy, and UP resource assignment. The vBRAS-UP terminates access connectivity, enforces forwarding and QoS policy, maintains subscriber counters, and handles the network-side transport functions. During PPPoE session setup, protocol messages reach the CP through the protocol channel. After the CP decides the applicable services, it sends session state and forwarding entries to the UP over the control channel, commonly associated with CUSP.
Management functions such as querying configuration or delivering equipment settings are distinct and can use NETCONF. Supported UP forwarding ASICs apply the installed user state without hairpinning ordinary traffic through the CP. This architecture permits centralized subscriber management together with distributed, scalable forwarding capacity.

NEW QUESTION # 62
In BGP EVPN, which of the following route types is used to advertise external routes?
Answer: A
Explanation:
Huawei Reference Verification:
Huawei BGP EVPN defines route types to distribute distinct categories of Ethernet VPN reachability. Type 1 identifies Ethernet Auto-Discovery information, Type 2 MAC/IP bindings, Type 3 inclusive multicast information, and Type 4 Ethernet Segment information. Type 5 is the IP Prefix route and advertises IPv4/IPv6 prefixes, including external routes imported from another protocol or routing domain. RFC 9136 standardizes EVPN IP Prefix Advertisement route type 5. Therefore the correct selection for external IP-prefix reachability is B.
Technical Deep Dive:
B is correct. EVPN is an MP-BGP control plane capable of supporting Layer 2 bridging and Layer 3 service distribution over an MPLS or VXLAN transport. A remote subnet or imported external prefix does not require advertising every individual destination MAC address. Instead a Type 5 IP Prefix Advertisement announces the network prefix, attributes and associated next-hop information. A receiving PE imports it according to route-target policy, resolves the EVPN next hop and installs the forwarding entry in the correct tenant or VPN table. Type 2 MAC/IP routes mainly represent host address bindings, Type 3 supports BUM transport setup, Type 1 supports Ethernet Auto-Discovery and Type 4 Ethernet Segment information. Thus the presence of five offered route types does not make the question multi-answer: Type 5 alone is the IP-prefix route. VRP verification can use `display bgp evpn all routing-table` and the relevant VPN-instance route display.
