質問 # 44
An IRB sub-interface that is being used to interconnect a MAC-VRF to an IP-VRF, is configured with anycast-gw set to true and anycast-gw enabled.
Which of the following statements is FALSE?
正解：B
解説：
Comprehensive and Detailed 150 to 250 words of Explanation From [SR Linux EVPN and Data Center Interconnect/Course Guide/topics]:
An anycast-gateway IRB allows multiple PEs to present the same default-gateway IP address to hosts in the same subnet. This is the mechanism that enables distributed gateway behavior in EVPN fabrics. The same anycast gateway IP may be configured on equivalent IRB subinterfaces across remote PEs participating in the same IP-VRF, allowing hosts to use the nearest leaf as their default gateway without changing their gateway address. SR Linux also associates gateway MAC information with the IRB, including virtual gateway MAC behavior used inside the MAC-VRF forwarding table. Option C is false because the anycast gateway IP is not treated as a normal unique host route that appears in the IP-VRF route table alongside the subnet prefix. The subnet route is installed for the connected network, but the shared anycast gateway address is a gateway function, not a separately advertised host endpoint that should appear as ordinary routed host reachability. Treating the anycast IP as a regular host route would undermine the distributed gateway model and create ambiguous ownership across PEs. Reference: IRB anycast gateway, MAC-VRF/IP-VRF interconnection, distributed default-gateway operation.
質問 # 45
When configuring the EVPN MP-BGP route reflector sessions between the leaf and spine routers, which of the following statements is TRUE?
正解：B
解説：
Comprehensive and Detailed 150 to 250 words of Explanation From [SR Linux EVPN and Data Center Interconnect/Course Guide/topics]:
In SR Linux BGP configuration, parameters defined at a more specific hierarchy level can override broader protocol-level settings. Therefore, if a `local-as` value is configured within the BGP group used for EVPN MP-BGP route-reflector sessions, that value overrides the AS number configured directly under the BGP protocol for that group's sessions. Option A is correct. Option B is false because the cluster ID is configured on the route reflector, not on every participating client. The cluster ID identifies the RR cluster and helps prevent route-reflection loops. Option C is false because redundant route reflectors normally operate in parallel rather than as strict primary/backup devices; clients can peer with both for resilience. Option D is misleading because EVPN route reflectors are used to avoid a full mesh of overlay MP-BGP EVPN sessions between leaves, not to replace ordinary underlay eBGP leaf-spine routing sessions. In a clean fabric design, the underlay provides IP reachability, while the EVPN overlay uses MP-BGP sessions, often via route reflectors, to distribute tenant reachability. Reference: SR Linux BGP hierarchy, EVPN route reflector sessions, local-AS override, cluster ID behavior.
質問 # 46
Consider the exhibit.
The network is going to be designed to use interface-less symmetric routing.
Which of the following statements is TRUE?
正解：A
解説：
Comprehensive and Detailed 150 to 250 words of Explanation From [SR Linux EVPN and Data Center Interconnect/Course Guide/topics]:
In interface-less symmetric routing, the EVPN fabric exchanges host forwarding information using EVPN route type 2 MAC/IP advertisements. RT-2 carries the host MAC address and, when present, the associated host IP address, allowing remote PEs to build the forwarding state needed for distributed gateway operation. Unlike asymmetric routing, interface-less symmetric routing does not require every MAC-VRF to be instantiated on every PE. The design scales better because each leaf only needs the locally attached MAC-VRFs plus the shared IP-VRF/routed VXLAN construct for inter-subnet forwarding. Option B describes an asymmetric forwarding pattern more than a symmetric one; in symmetric routing, both ingress and egress PEs perform routed forwarding functions through the IP-VRF. Option C is also incorrect because anycast gateway is fundamental when multiple leaves provide the same default-gateway service for a subnet. Therefore, the true statement is that forwarding information is exchanged using EVPN route type 2 updates. Reference: interface-less symmetric routing, EVPN RT-2 host MAC/IP signaling, distributed IRB operation.
質問 # 47
A host is connected to multiple PEs through multi-homing.
Which of the following is NOT a function of the EVPN route-type 4 route?
正解：B
解説：
Comprehensive and Detailed 150 to 250 words of Explanation From [SR Linux EVPN and Data Center Interconnect/Course Guide/topics]:
EVPN route type 4 is the Ethernet Segment route. Its core role is to advertise Ethernet Segment membership so that PEs attached to the same multi-homed segment can discover each other. This discovery is essential for multi-homing procedures such as DF election, split-horizon behavior, and redundancy handling. When multiple PEs advertise the same ESI, the EVPN control plane can build the candidate set of PEs that participate in that Ethernet Segment. This enables DF election for BUM forwarding and supports the correct interpretation of the segment's redundancy model. The incorrect statement is option C. The election algorithm itself is not the basic function of the route type 4 advertisement in the way the question frames it. The route type is primarily about Ethernet Segment discovery and participation; the algorithmic decision process is derived from configured DF election behavior and candidate information, not from route type 4 acting as a generic algorithm identifier. Therefore, route type 4 enables DF procedures, but it is not described as the mechanism that identifies the election algorithm type. Reference: EVPN RT-4 Ethernet Segment route, DF election, multi-homing discovery.
質問 # 48
Consider the exhibit.
Based upon the information in the screen captures, which of the following statements is FALSE?
正解：A
解説：
Comprehensive and Detailed 150 to 250 words of Explanation From [SR Linux EVPN and Data Center Interconnect/Course Guide/topics]:
The exhibit describes an EVPN IRB environment where MAC-VRF100 and IP-VRF-100 exchange host reachability through local learning and EVPN advertisements. Leaf-1 can advertise EVPN route type 2 updates containing host MAC/IP information for MAC-VRF100. This is the normal mechanism used to distribute endpoint bindings learned from local hosts. If IP-VRF-100 is not configured for prefix advertisement, Leaf-1 will not generate EVPN route type 5 updates for that IP-VRF, so option A is consistent. The ARP cache in the IP-VRF is normally required for local subnet host resolution; remote host reachability can be learned through EVPN rather than requiring every remote ARP entry to be learned by local data-plane ARP. Option B is false because ARP/GARP snooping is not performed by the IRB interface in the manner stated. ARP/GARP learning for proxy ARP and MAC/IP advertisement is associated with the MAC-VRF bridge-domain behavior and the local access side, not with the IRB subinterface indiscriminately snooping all ARP/GARP messages as described. Reference: EVPN IRB operation, RT-2 host MAC/IP advertisement, RT-5 behavior, ARP/GARP learning scope.
