Route redistribution in OSPF (Open Shortest Path First) allows routes learned from one routing protocol to be advertised and used in another routing protocol. Redistribution can be useful in scenarios where multiple routing protocols are used within an enterprise network. Here’s a basic guide on how to configure route redistribution in OSPF:

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:

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:

A while back I was assigned to work on a project which requires, among other things, to deploy wireless in 4 offices.
I decided to interconnect the office in a hub and spoke fashion. For wireless I decided to use Cisco 9130AXI Wireless Access Points and a Cisco Catalyst 9800-CL Wireless Controller.
