bookmark_borderHow to configure OSPF with BGP on top

Configuring OSPF (Open Shortest Path First) with BGP (Border Gateway Protocol) on top is a common practice in large-scale networks where OSPF is used for intra-domain routing and BGP is used for inter-domain routing. This approach is often referred to as “OSPF as the IGP (Interior Gateway Protocol) and BGP as the EGP (Exterior Gateway Protocol).” Here’s a basic guide on how you can configure OSPF and BGP coexistence:

bookmark_borderHow to configure BGP AS Prepending

BGP AS (Autonomous System) prepending is a technique used to influence the inbound traffic by making a particular Autonomous System path less attractive. This is achieved by adding the AS number multiple times to the AS path attribute of BGP updates sent to a neighbor. The idea is to make the AS path longer, and therefore less preferred, in order to influence incoming traffic.

Here’s a general guide on how to configure BGP AS prepending:
