In this recipe, we will outline how to configure eBGP as the underlay routing protocol for our sample leaf/spine DC fabric. We are going to build the eBGP peering setup, using the P2P IP address between the leaf switches and spine switches. The BGP autonomous system number (ASN) assignment is as shown in the following table:
Node |
BGP ASN |
Spine01 |
65100 |
Spine02 |
65100 |
Leaf01 |
65001 |
Leaf02 |
65002 |
Leaf03 |
65003 |
Leaf04 |
65004 |
