MPLS over IP Encapsulations and Comparison between MPLS over LSP
Do you need an LSP for MPLS ?
In this post, I will go through below topics. This is one of the points which network engineers struggle to understand as I have seen.
Design considerations for network mergers and acquisitions
Network mergers and acquisitions are the processes which can be seen in any type of businesses. As a network designers, our job to identify the business requirements of both existing networks and the merged network and finding best possible technical solutions for the business.

Fast Convergence and the Fast Reroute – Definitions/Design Considerations in IP and MPLS
Fast Convergence and the Fast Reroute Network reliability is an important design aspect for deployability of time and loss sensitive applications. When a link, node or SRLG failure occurs in a routed network, there is inevitably a period of disruption to the delivery of traffic until the network reconverges on the new topology.

One of my readers sent me a question along these lines…
VXLAN Network Identifier is 24 bit long, giving 16 us million separate segments. However, we have to map VNI into VLANs on most switches. How can we scale up to 16 million segments when we have run out of VLAN IDs? Can we create a separate VTEP on the same switch?
VXLAN is just an encapsulation format and does not imply any particular switch architecture. What really matters in this particular case is the implementation of the MAC forwarding table in switching ASIC.
