Hi Experts, We are planning to have a CLOS Fabirc (VXLAN EVPN) up and I am finding it difficult when trying to optimize routing. I have attached a diagram for better understanding. We have multiple VRFs (tenants) We are peering with and upstream serv...
Hello, On the datasheet accessible via Cisco 25GBASE SFP28 Modules Data Sheet on page 11, we see: "Connectors: Dual LC/PC connector (SFP-25G-SR-S, SFP-10/25G-CSR-S SFP-10/25G-LR-S, SFP-10/25GLR-I and SFP-25G-ER-I)." It doesn't explicitly mention th...
Hello, I'm building out a vPC design to introduce the technology to DC/Aggregation Nexus 9ks. I've built out most of the design in CML but I'm unsure based off Cisco documentation/Forums on how many vPC domains can be connected in a double sided conf...
Hi, I plan to use QSFP-4X10G-AOC10M connect between cisco N9K-C93180YC-FX3 from 40G QSFP to other switch brand , Huawei. I'm not quite sure about the compatibility. Is it possible to use Cisco AOC breakout to connect 10G SFP to Huawei switch? What sh...
Hello everyone testing comand fast-convergence on vpc, i couldn't understsnd, goal of fast convergence is that when a peer link breaks, VPC ports stop faster than SVI ports, or vice versa, SVI ports can stop earlier. This leads to traffic arriving on...

Hi, I have two Cisco Catalyst 9300 switches in two different data centers configured as VTEPs with BGP EVPN VXLAN. The VXLAN overlay network has VNI-to-VLAN mappings configured. However, how do I connect the VXLAN overlay network (with VNI mappings) ...
NXOS on this switch is 9.3.8 which suppose to be safe to avoid this error, however still seeing this error in log.
Hello All, we have 2 core Nexus 7K switches in VPC. And having fabric-path between them. One of the SVI VLAN directly connected through fabricpath is not pinging each other but one side arp learning and another side arp is incomplete what would be th...
Hi, I'm running into a scenario where a Nexus switch has two root ports and I'm trying to figure out:- if this is normal behavior- whether or not I have a mistake in my configuration- what would be the impact on traffic flow with two root ports Desig...
Hello,Hope you are doing well!I was wondering if anyone else had done a similar setup as this one.We have EVPN with DAG. I am trying to configure route leaking between the overlay and underlay. This would be bidirectional with the overlay receiving a...
