Class Based Forwarding over RSVP LSPs Design Consideration

Class-Based Forwarding (CBF) is an effective component that introduces an additional layer of traffic engineering, enabling the differentiation of traffic based on business needs. It allows low-priority traffic to traverse slower paths while ensuring that business-critical traffic utilizes the fastest or best available paths

Consolidating WAN Backbone with EVPN

Recently I was exploring how to consolidate layer-2 & layer-3 connectivity across WAN backbone network. In this write I have covered (IP-Prefixes handling as EVPN Type 5 Routes) and in subsequent writeup I will cover E-LAN and E-Line use cases as well.

Inter-Domain Traffic-Engineering Based MPLS-LSPs

Recently I was exploring solution to have inter-domain traffic-engineerig based MPLS LSPs and came up with following writeup (after going through relevant rfc and vendor Implementation document (my favourite Junos). Please glance through it on my github home page. thanks

Understanding-BGP-Route-Reflector-Mysteries

It’s been while I was away from tech blog writing , this week end I powered on my EVE-NG based lab running on Dell R820 Edge Server and explored some mysteries behind BGP Route Reflector. Please read through it on my Github (https://github.com/kashif-nawaz/Understanding-BGP-Route-Reflector-Mysteries)
