Routing with BGP

ACI supports three routing protocols: BGP, OSPF, and EIGRP. We will start by looking at BGP. 

As we go forward, we will see that the steps taken to implement OSPF and EIGRP are very similar. The steps, from a 10,000-foot view, are to create an "external routed network," configure an interface, and associate this interface to a bridge domain. To get a visualization of the type of deployment we would be looking at, refer to this figure:

How to do it...

1. Navigate to TenantA | Networking | External Routed Networks.
2. Right-click on this and select Create Routed Outside.

3. Give the new Routed Outside a name.
4. Select the BGP checkbox.
5. Select the desired VRF.

6. Click on NEXT.
7. Click on FINISH.

8. The new profile will appear in the work pane. Selecting it will show us the options we have configured so far.

9. Select Node Profiles on the right-hand side and click on the plus sign.

 

 

10. Name the profile, and click on the plus sign next to Nodes.

11. Select a node from the drop-down menu.

12. Enter a Router ID.
