Hi community,I know that when doing 802.1x on "traditionnal network" it is not a good idea to change the IP address (vlan) of the user between the machine authentication and the user authentication, otherwise the IP stack of the PC may not run a new ...
I just build a SD-Access fabric with two borders to go out to the DNAC and ISE through the fusion.My DNAC v. 2.1.2.5 is configuring with 3 interfaces:- eno1: for the gui access- enp94s0f0 for the communication to the fabric- enp94s0f1 for the cluster...
All,why get the command "bgp router-id interface loopback0" removed from the running-config when loopback0 is shutdown during operation ? Losing the BGP router-id isn't nice for bgp protocol.Nevertheless there are usecases e.g. SDA route convergence ...
Resolved! SDA Limitations for 6807-XL
Hello all,I'm in the process of spec'ing out equipment for a possible SDA roll-out in somewhat of a green field deployment. We would replace all our access layer switches with C9300 stackables at the edge. We're running a pair of 6807-XL switches i...
In a fully deployed SDA network, how would you go about capturing as much traffic as possible (SPAN/RSPAN/ERSPAN)? If you have a security solution that does full packet capture the goal would be to capture as much traffic as possible, in an SDA arch...
Resolved! Migration to SD-Access
Hello everyone,I am looking for a guidance on Cisco SD-Access migration from traditional network. I am working on building new SDA fabric physically alongside to legacy network. SDA-access consists of new switches. Once that Sd-access is all setup an...
Hello we are currently upgrading our network all c9k series and we are installing only DNA the network will be layer 3 routed access my 1st question can i use DNA to auto config my switches , or better to configure my switches manually then att...
Resolved! SD-Access Dual Default Border
In a Deployment with a Dual Default Border Setup. What kind of connectivity must be configured between the two border?Is it necessary to have a ISIS relationship between them? Or can I remove this configuration (from LAN Automation) after applying th...
Resolved! Route leaking using Prefix-Lists on Fusion Router only works with directly connected networks
Hi All, I'm trying to emulate as best as possible SD Access under Eve-NG using CSR routers as the Border node and Fusion Router and a combination of CSRs and L2 IOL switches to emulate Fabric nodes. The CSR's don't work with subinterfaces so I have h...
We are in the process of building a SD Access lab. Based on some sample topologies we've been provided with this is what our lab looks like.The top two switches are our Fusion devices (Cat 3750Xs), the middle two are Cat 9300 Border nodes and the tw...
Hello,I have implemented SDA Fabric.According to the different cisco design guide, on Border nodes BGP should be configured like this : router bgp [underlay AS number] bgp router-id [interface] bgp log-neighbor-changes ! fusion router is an eBGP neig...
Hello Cisco community,Recently we've tested a failover of one server connected to the Fabric. The server has 2 management interfaces, each connected to a different edge switch, one interface is active and the second one in standby mode. When the fabr...
Imagine a large enterprise with both IT and OT networks where challenges include: 1) Keeping up with lifecycle - too many network silos engineered for specific use cases, too many platforms to lifecycle.2) Operations - network landscape is complex, s...
In traditional networks a subnet has (usually) a 1:1 association with a location. In desktop management systems (such as Microsoft SCCM) these subnet based "boundaries" are used to perform client management tasks. Using SD-A a subnet is now a fabric ...
