Seamless MPLS and the usage Scenario for it Seamless MPLS establishes a BGP LSP across the access, aggregation, and core layers and transmits services along the E2E BGP LSP. Service traffic can be transmitted between any two points on the LSP. The seamless MPLS network architecture maximizes service scalability using the following functions: Allows access …

Hi my friends , Today I found a very good Video that explain how the services are working on IPRAN this will help you soo much to understand how the traffic is moving inside the network and how its encapsulated Here you will see how the encapsulation if the access node is Ethernet :

A basic BGP/MPLS IP VPN is an L3VPN network that covers only one carrier’s network, which is an MPLS backbone network that does not span multiple ASs, as shown in Figure 1. A basic BGP/MPLS IP VPN has the following characteristics: Transmits packets using extended BGP. Encapsulates and transmits VPN packets over MPLS LSPs serving as …

Fully meshed connections need to be established between IBGP peers to ensure the connectivity between IBGP peers. If there are n CX devices in an AS, n x (n-1)/2 IBGP connections need to be established. When there are a lot of IBGP peers, network resources and CPU resources are greatly consumed. Route reflection can solve the …
