The topology involves both Layer 3 and Layer 2 components. You can view this topology using the search query

vm_name_1

to

vm_name_2

. If a path exists, the VM-to-VM path visualization proceeds to populate all the components that exist between

vm_name_1

to

vm_name_2

and also draws an animated path. If the routers are physical, then they are shown outside the boundary.

In the path topology, you see the VM-to-VM path between the source and the destination. If the default path is not configured between the VMs, an error message appears to inform that the path is not defined or the router interface is not found.

For Kubernetes, the Path topology displays the path for the following scenarios:

Kubernetes Service to Kubernetes Service
Kubernetes Service to Kubernetes Pod
Kubernetes Pod to Kubernete Pod
The path involving physical devices is not supported.

The

Path Via Load Balancer

option lists all the load balancers that are used in between the path from the selected source and the destination VM. To see the path between the VMs via a particular load balancer, select the load balancer name from the list. If you hover the mouse on load balancer component on the path topology, you see the following details:

Virtual Server name
Load Balancer IP address
Port number
Load Balancer Algorithm
The default gateway that was taken from the load balancer.

You can also see the routing components on the path topology.

If you hover your mouse on any of the routers, edges, or LDRs that are involved in the path, the complete routing or NAT information is shown.

The VM Underlay section that is on the right side of the VM Path topology shows the underlay information of the VMs involved and their connectivity to the top of the rack switches and the ports involved. For Kubernetes entities, VM Underlay displays the VM or the Kubernetes node information on which the Pod resides.

In the VM underlay section, the components are labeled if you select

Show labels

under

Path Details.

In this section, the drop-down list at the top shows the endpoint VMs and the active VMs at the edges. For each edge VM, the neighboring drop-down menu shows the ingress and the egress interface IP addresses. Based on the selection, the underlay path for that particular interface is shown.

You can also reverse the path direction using the arrows on top of the topology map.

The topology map gives more visibility regarding the ports involved in the VM-VM path. In the

Path Details

section, the name of the actual port channel is shown.
