kubectl describe secret avi-token-esdf0 -n default
==
*Enter the Master IP address & Token in Cloud Config:
https://10.1.10.160:6443 ==> Kubernetes
https://10.1.10.160:8443 ==> Openshift
*Create IPAM Profiles with below subnets:
NorthSouth-IPAM(Should be route-able)
10.52.201.0/24: 10.52.201.14 - 10.52.201.30
EastWest-IPAM
172.50.0.0/16 172.50.0.10 - 172.50.0.250
*Create DNS Profiles with below domains:
NorthSouth_DNS [avi]
EastWest-DNS [avi]
*Go to Tenant '''Default''' & Check VS status
*Either Disable Kube-Proxy(which is default LB in Kubernetes) or Give it a different IP than East_West Subnet.

*Test reachability:
curl 10.52.201.15 ==> Fails; will not hit the HTTP Request policy to fwd traffic to Pool; will hit 404 policy.
curl -H "HOST:httptest" 10.52.201.15
http://httptest
*Avi HTTP Request policies:
oshift-k8s-cloud-connector--httptest--/--
Path begins with (/)
Host Header equals 'httptest'
Content Switch:
Pool Group: httptest---aviroute-poolgroup-8080-tcp
host--path--drop--rule--httptest--[u'/']
Path does not equal (/)
Host Header equals 'httptest'
Content Switch
Status Code: 404
all-nomatch-host--drop--rule
Host Header does not equal 'httptest'
Content Switch
Status Code: 404
