There are a lot of options when it comes to vPC. What enhancements should you consider? I’ll go through some of the options worth considering. Peer Switch – The Peer Switch feature changes how vPC behaves in regards to STP.
Cisco vPC in VXLAN/EVPN Network – Part 5 – Potential Pitfalls
Like I hinted at in an earlier post, there are a some failure scenarios you need to consider for vPC. The first scenario we can’t really do much with, but I’ll describe it anyway. The topology is the one below:
Cisco vPC in VXLAN/EVPN Network – Part 4 – Fabric Peering
Like I mentioned in a previous post, normally leafs don’t connect to leafs, but for vPC this is required. What if we don’t want to use physical interfaces for this interconnection? This is where fabric peering comes into play. Now,
Cisco vPC in VXLAN/EVPN Network – Part 3 – Verifying Connectivity
The following topology is used: We want to verify connectivity and traffic flow towards: Let’s start with the gateway. The gateway is at 10.0.0.1 and has a MAC address of 0001.0001.0001: This is an anycast gateway MAC. When initiating a
