BGP Protocol Fundamentals: Architecture, States, and Path Selection
Routes are generally categorized into two types:
Directly Connected Routes: These routes have a default preference value of 0, representing the highest priority.
Non-Directly Connected Routes: These are further divided into static routes (default preference 60) and dynamic routes. Dynamic routing protocols fall into two categories:
IGP (Interi ...

SRv6 Traffic Engineering Policy Simulation in H3C Cloud Lab
Overview
This simulation experiment demonstrates the configuration and behavior of SRv6 Traffic Engineering (TE) policies using H3C Cloud Lab. The goal is to understand how SRv6 Policy can be used to influence traffic paths via color-based steering, even though some connectivity issues may arise due to simulator limitations.
Topology and IP Con ...

BGP Extended Knowledge Summary
1. BGP Route Advertisement Considerations
In BGP, there are two primary methods for route advertisement:
Advertise directly connected routes on each BGP-speaking device
Advertise routes learned through IGP from non-BGP devices within the AS (most common scenario)
When BGP advertises routes from the local routing table, it carries the local IG ...
