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...
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 ...
I installed DNA Center server, at server I added two border nodes (Cisco catalyst 9500) with discover OKI added 8 switch edge with LAN Automation (Cisco catalyst 9400) OKI created fabric between two Fusion routers (cisco catalyst 9300) and two border...
So I've been told that Cisco DNA (or "software defined campus") has ways to do wired/wireless handoff, so that you could seamlessly transition from a wired connection to a wireless one without dropping traffic. Supposedly this works because it can re...
Hello everyone, I am in the middle of an SDA implementation for a customer. DNA center version is 1.3.3.9. We have 9500s and 9200s as border and edges with 16.12.x version software on them. For wireless we have 9800-L WLC with 9115AX access points. W...
In the past, enterprise MPLS was used to deploy macro-segmentation capability. Today, both SD-WAN and SD-Access have their own native macro-segmentation techniques (service VPNs & VNs). While interoperability with enterprise MPLS is possible, it cert...
I believe I understand the basic differences between using SD-Access transit and using ip transit between different fabric sites. One of the big benefits of SD-Access transit is the preservation of SGT tagging between sites. This is where Im a littl...
Hello,Cisco DNA Center last version 2.1.2.4 is supported Virtual Wireless Controller version 8.10.130.0 Best regards,
Hi allToday I wanted to upgrade from 1.3.3.9 to 2.1.2.4. Currently, the upgrade process fails with the bug described in CSCvv72444. Who can help? Is there a solution?Kind regards,Roger
HiI am in the process of introducing SDA into our network and would prefer to route-leak between the VNs on the border router itself rather than handoff to the Fusion Router. I am aware of the reasons a Fusion Router is used (no automated changes can...
