You want to ensure that VXLAN traffic from the xe-0/0/12 interlace is being encapsulated by logical vlep.32770 and sent to a remote leaf device in this scenario, which command would you use to verify that traffic is flowing?
Answer(s): C
VXLAN Traffic Verification:To ensure VXLAN traffic from the xe-0/0/12 interface is correctly encapsulated by the logical vtep.32770 and sent to a remote leaf device, it is essential to monitor the relevant interface statistics.The command show interfaces terse vtep.32770 statistics provides a concise overview of the traffic statistics for the specific VTEP interface, which can help verify whether traffic is being correctly encapsulated and transmitted.This command is particularly useful for quickly checking the traffic counters and identifying any potential issues with VXLAN encapsulation or transmission. It allows you to confirm that traffic is flowing as expected, by checking the transmitted and received packet counters.Data Center
Monitoring interface statistics is a crucial step in troubleshooting and validating network traffic, particularly in complex overlay environments like EVPN-VXLAN.
Exhibit.Connections between hosts connected to Leaf-1 and Leaf-2 are not working correctly.
Answer(s): C,E
Issue Analysis:The problem in the exhibit suggests a mismatch in configuration parameters between Leaf-1 and Leaf-2, leading to communication issues between hosts connected to these leaf devices.Configuration Mismatches:Service-ID: Leaf-1 has service-id 1 configured, while Leaf-2 does not have this parameter. For consistency and proper operation, the service-id should be the same across both leaf devices. VRF Target: Leaf-1 is configured with vrf-target target:65000:1, while Leaf-2 is configured with vrf- target target:65000:2. To allow proper VRF import/export between the two leafs, these should match.Corrective Actions:C . Configure the set switch-options vrf-target target:65000:1 parameter on Leaf-2: This aligns the VRF targets between the two leaf devices, ensuring they can correctly import and export routes. E . Configure the set switch-options service-id 1 parameter on Leaf-2: This ensures that both Leaf-1 and Leaf-2 use the same service ID, which is necessary for consistency in the EVPN-VXLAN setup.Data Center
Correct configuration of VRF targets and service IDs is critical in EVPN-VXLAN setups to ensure that routes and services are correctly shared and recognized between different devices in the network fabric.
What are three actions available tor MAC move limiting? (Choose three.)
Answer(s): A,D,E
MAC Move Limiting:MAC move limiting is a security feature used in network switches to detect and mitigate rapid changes in MAC address locations, which could indicate a network issue or an attack such as MAC flapping or spoofing.When a MAC address is learned on a different interface than it was previously learned, the switch can take various actions to prevent potential issues.Available Actions:A . drop: This action drops packets from the MAC address if it violates the move limit, effectively blocking communication from the offending MAC address. D . log: This action logs the MAC move event without disrupting traffic, allowing network administrators to monitor and investigate the event.E . shutdown: This action shuts down the interface on which the MAC address violation occurred, effectively stopping all traffic on that interface to prevent further issues.Other Actions (Not Correct):B . filter: Filtering is not typically associated with MAC move limiting; it generally refers to applying ACLs or other mechanisms to filter traffic.C . enable: This is not an action related to MAC move limiting, as it does not represent a specific reaction to a MAC move event.Data Center
MAC move limiting is crucial for maintaining network stability and security, particularly in environments with dynamic or large-scale Layer 2 networks where MAC addresses might frequently change locations.
Exhibit.Referring to the exhibit, the spinel device has an underlay BGP group that is configured to peer with its neighbors' directly connected interfaces. Which two statements are true in this scenario? (Choose two.)
Answer(s): A,D
Understanding BGP Configuration in the Exhibit:The exhibit shows a BGP configuration on spine1 with a group named underlay, configured to peer with directly connected interfaces of other devices in the network. Multipath multiple-as: This statement allows the router to install multiple paths in the routing table for routes learned from different ASes, facilitating load balancing.Key Statements:A . The multihop statement is not required to establish the underlay BGP sessions: In this case, the BGP peers are directly connected (as indicated by their neighbor IP addresses), so the multihop statement is unnecessary. Multihop is typically used when BGP peers are not directly connected and packets need to traverse multiple hops.D . Load balancing for the underlay is configured correctly: The multipath { multiple-as; } statement in the configuration enables load balancing across multiple paths from different autonomous systems, which is appropriate for underlay networks in data center fabrics.Incorrect Statements:C . The multihop statement is required to establish the underlay BGP sessions: This is incorrect because the peers are directly connected, making the multihop statement unnecessary. B . Load balancing for the underlay is not configured correctly: This is incorrect because the configuration includes the necessary multipath settings for load balancing.Data Center
BGP configurations in EVPN-VXLAN underlay networks are crucial for ensuring redundancy, load balancing, and efficient route propagation across the data center fabric.
