because routing occurs on ingress with asymmetric IRB. This means that packets travel to their destination on the destination VNI, which is 1615 in this case.

11.3
Validate routing using the indirect gateway
Two tests are run in this section.
In the first test, a VM that has its default gateway set to the indirect gateway pings the loopback interface on
the Gateway/Firewall switch, 1.1.1.1, to verify connectivity to external networks.
VM-1616-1 has IP address 172.16.16.1. It is on R740xd-1 connected to the first leaf pair in Rack 1. Its default
gateway is the indirect gateway, 172.16.16.253. The Gateway/Firewall switch is connected to the third leaf
pair in Rack 3 as shown in Figure 22.
A packet capture of the successful exchange with a ping request selected is shown in Figure 25.
Packet capture showing successful ping to 1.1.1.1
The first red box shows the source and destination are the VTEPs for Rack 1 and Rack 3 respectively. The
second red box shows the packet is encapsulated with VXLAN on VNI 1616. The third red box shows the
source and destination IP addresses.
In the second test, the same VM, VM-1616-1, pings VM-1615-3 to demonstrate the path taken from a VM that
uses the indirect gateway to a VM that uses an anycast gateway. VM-1615-3 has IP address 172.16.15.3. It is
on R740xd-3 connected to the leaf pair in Rack 2 as shown in Figure 22. Its default gateway is an anycast
gateway, 172.16.15.253.
A packet capture of the successful exchange with a ping request selected is shown in Figure 26.
