Hi,We have a L3Out in which OSPF is enabled. Now, we want to enable eBGP and disable OSPF. The border leaf (and its sub-interface), the external EPG and contracts will not change.1. Is is possible to simply change the protocol in the existing L3Out f...
My ACI managed datacenter recently went through a full power down and startup due to planned maintenance. All ACI devices were powered completely down for 24+ hours. Once maintenance was complete, the ACI fabric was restarted in the following order. ...
Hi folks, I have a client with their production, single-pod fabric running 3.2(3), the one which can be directly upgraded to 4.2(7q). We are proposing upgrading the production fabric first, then going to introduce the other Pod because it is net-new....
Hello, i need to add several hundred EPG to AEP. With single physical Domain associated to AEP it was straight forward. Locate profile of port attached to the AEP and then add the vlans via "switchport trunk allowerd vlan...." which automatically pop...
Hello everyoneI have a course in Software-Defined Wide Area Networks released in 2018; my question is: Are there any differences or updates at any face of SDN since then?Thank you
Hello! I have installed the Cisco ACI simulator on an ESXi host in our datacenter in order to learn about ACI. I've provisioned a seperate VLAN and subnet for the purposes of this deployment. Deploying the OVA went without a hitch, and I passed throu...
Hi Our security team is asking if it's possible to deploy a NDR solution in our datacenter fabric to ingest "all traffic" for analysis. All they're asking is to SPAN all traffic on each Leaf switch into the NDR device. I've made it clear that they ca...
Hi all,we were on APIC ver. 4.2(5) and upgraded to 4.2(7), but after upgrade we could notchange interface description anymore as we did before:Fabric – Inventory - <Pod> - <Leaf-Switch> - Interface – physical interface - <Interface>as soon as l chang...
Dear Community,I have a question about L3OUT with static routes. We have the following scenario. The L3OUT is distributed over 4 Leafs, each with 2 VPC pairs (SVI). The question: Can I assignto the SVIs one secondary IP address for all 4 Leafs, or...
Hello guys. We want create better granularity in ACI so We want separate AEPs per Server and relate them to pdms. Those changes are related to many already created aep with wide range of vlan pools in pdm....Is there data flow affected with aep chan...
In L3OUT we can use OSPF, EIGRP, Or BGP when choosing routing protocols. In case of Multi-tenancy , We need to use multiple instances of the routing protocol (OSPF/EIGRP). one instance for each tenant since each one is in a different VRF. This makes ...
Hello,I have ACI fabric (APIC v5.1) and legacy backbone routers (NX-OS 9.3). ACI config is trivial: one user tenant, one VRF and one L3Out with static routing to the backbone using L3 routed interface.Now, I have to extend second VRF from NX-OS backb...
Hello community,This is NOT a post to complain about bugs or missing features, but an attempt to document as many NAMING inconsistencies as practical in the Cisco ACI APIC UI (NOT the MSO UI).But I'd be happy for as many people as possible could cont...
What would be the behaviour of each pod as IPN breaks in a two-pod design? The White Paper seems to mention only for APIC cluster quorum not being achieved for one pod. However most of the time it is forwarding behaviour that we care about: - Between...
