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.
Do we still lose packet with fast reroute? One of my students asked me this question. And I would like to share the answer with everyone.
Multi-Protocol Label Switching Transport Profile (MPLS-TP) is a new technology developed jointly by the ITU-T and the IETF. The key motivation is to add OAM functionality to MPLS in order to monitor each packet and thus enable MPLS-TP to operate as a transport network protocol.
CSC Carrier Supporting Carrier is a hierarchical MPLS VPN architecture between the Service Providers.
You need OSPF or IS-IS to distribute link information such as reserved, unreserved and used bandwidth, metric, link colouring information.These informations are used by CSPT ( Constraint based shortest path first ) algorithm.
Actually all are the same thing. VPWS stands for virtual private wire service , VLL stands for virtual leased line and EoMPLS stands for Ethernet over MPLS.
Is MPLS mandatory for Traffic Engineering? What is Traffic Engineering in the first place ?
There are many posts about MPLS Traffic Engineering with RSVP on the Website, in this post we will look at the alternative approaches to the MPLS TE with RSVP.
MPLS Traffic Engineering is a mechanism that provides cost savings in an MPLS networks.
Is Inter-AS MPLS VPNs commonly deployed ? In real-life deployment which Inter-AS MPLS VPN Option is most common ? What are the use cases of Inter-AS MPLS VPNs ? This is not a theory post , I will share practical information with you.
