Question 11

Report Export Collapse

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?

monitor traffic interface xe-0/0/12
monitor traffic interface xe-0/0/12
show interface terse vtep.32770
show interface terse vtep.32770
show interfaces terse vtep.32770 statistics
show interfaces terse vtep.32770 statistics
show interfaces vtep.32770 detail
show interfaces vtep.32770 detail
Suggested answer: C
Explanation:

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

Reference:

Monitoring interface statistics is a crucial step in troubleshooting and validating network traffic, particularly in complex overlay environments like EVPN-VXLAN.

Connections between hosts connected to Leaf-1 and Leaf-2 are not working correctly.

Referring to the exhibit, which two configuration changes are required to solve the problem? (Choose two.)

Configure the set switch-options route-distinguisher i92.168.100.50:i parameter on Leaf-1.
Configure the set switch-options route-distinguisher i92.168.100.50:i parameter on Leaf-1.
Configure the set switch-options service-id 1 parameter on Leaf-2.
Configure the set switch-options service-id 1 parameter on Leaf-2.
Suggested answer: C, E
Explanation:

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

Reference:

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.
