configure the initial parameters, we will now be using OSPF in Area 0 for this example:<\/span><\/p>\n <\/p>\n
<\/p>\n
Create our Node Profile for each feature, OSPF Int Profile and Network EPG:<\/span><\/p>\n <\/p>\n
<\/p>\n
<\/p>\n
<\/p>\n
<\/p>\n
Once that is completed ,we need a simple config on our CSR:<\/span><\/p>\n <\/p>\n
<\/p>\n
Remind yourself to check for neighbors:<\/span><\/p>\nACI:<\/p>\n
<\/p>\n
CSR:<\/p>\n
<\/p>\n
<\/p>\n
<\/p>\n
Once we have neighbors, we can start doing routes.<\/span><\/p>\nACI:<\/p>\n
<\/p>\n
We now see the loopback from the CSR in our routing table.<\/span><\/p>\nCSR:<\/p>\n
<\/p>\n
<\/p>\n
While we are getting loopbacks from ACI, we are supposed to be receiving the 10.10.1.0\/24 within the External-BD. These issues usually live inside the bridge domain settings. So once you see them, investigate:<\/span><\/p>\nOur subnet is still set to private, hence we need to advertise externally and select the correct L3Out:<\/span><\/p>\n <\/p>\n
<\/p>\n
L3Out within BD:<\/p>\n
<\/p>\n
<\/p>\n
With these changes, ACI verifies routing on the CSR. Should you need a refresher on this step, feel free to check out the verified scalability guide for Cisco ACI. <\/span><\/p>\n <\/p>\n
<\/p>\n
Now we can now see the 10.10.1.0\/24 subnet on the external router.\u00a0 Our host can now ping the loopback of the router:<\/span><\/p>\n <\/p>\n
<\/p>\n
If we still can\u2019t hit the loopback of the router, look back at our design again. Notice how we still need a contract between the L3Out and the EPG, just like any other EPG to EPG communication.<\/span><\/p>\n <\/p>\n
<\/p>\n
Going back to earlier, we created and applied the service-graph template. Contracts were then created and applied on the Web EPG:<\/span><\/p>\n <\/p>\n
<\/p>\n
We must use this same contract on the L3Out Network EPG.\u00a0 If we apply correctly we should see communication take place:<\/p>\n
<\/p>\n
<\/p>\n
We can now verify ACI:<\/p>\n
Web Host:<\/p>\n
<\/p>\n
<\/p>\n
Now we can test CSR:<\/p>\n
<\/p>\n
There you have it! A working unmanaged service graph within ACI. Keep in mind that this is a simple implementation of the service graph. In a real-life situation, you would have very granular rules within your FW.\u00a0<\/span><\/p>\nThese implementations can vary in many ways. You could also include a one-arm load-balancer in this model with an additional bridge domain and more. <\/span><\/p>\n@_JBANK<\/p>\n","protected":false},"excerpt":{"rendered":"
