What is forwarding adjacency?

A forwarding adjacency is a traffic engineering label-switched path (LSP) that is configured between two nodes and that is used by the interior gateway protocol (IGP) to forward traffic. Forwarding adjacencies allow you to treat a traffic engineering LSP tunnel as a link in an IGP topology.

Which LSA is used for MPLS traffic engineering?

MPLS TE uses type 10 LSAs for intra-area MPLS TE.

Can MPLS support traffic engineering?

MPLS supports traffic engineering thus allowing network organizations to associate a Label-Switched Path (LSP) with whatever physical path they choose. MPLS also supports constraint-based routing, which ensures that an LSP can meet specific performance requirements.

How is traffic engineering done in MPLS?

Traffic Engineering in MPLS involves the technique of directing traffic that flows within a network. Several routing procedures implement packet forwarding for a secure transmission. MPLS TE allows exploitation of bandwidth in use rather than allocating new bandwidth to operate traffic engineering.

What are the components of MPLS TE?

MPLS TE uses an extension for existing protocols (Intermediate System-to-Intermediate System (IS-IS), Resource Reservation Protocol (RSVP), OSPF) to calculate and establish unidirectional tunnels that are configured according to the network restriction.

Which two protocols below you can choose as the routing protocol for MPLS TE?

There are two standardized protocols for managing MPLS paths: the Label Distribution Protocol (LDP) and RSVP-TE, an extension of the Resource Reservation Protocol (RSVP) for traffic engineering. Furthermore, there exist extensions of the Border Gateway Protocol (BGP) that can be used to manage an MPLS path.

Why is MPLS faster?

MPLS is much faster than traditional IP Routing, as it is based on the concept of the label to allow forwarding (rather switching) of packets. This type of forwarding is more efficient as it avoids overloading the CPU.

What is MPLS TP technology?

MPLS-TP is a packet transport technology based on MPLS. Also known as IP/MPLS, MPLS is a protocol-agnostic IETF standard used to carry circuit and packet traffic over virtual circuits known as Label Switched Paths (LSPs). With MPLS, LSP from source to destination is predetermined and a ‘label’ is applied to it.

Why we use MPLS traffic engineering?

The main advantage of implementing MPLS TE is that it provides a combination of ATM’s TE capabilities along with the class of service (CoS) differentiation of IP. In MPLS TE, the headend router in the network controls the path taken by traffic to any particular destination in the network.

What are two characteristics of MPLS TE tunnels?

Correct Answer: B

• They are unidirectional.
• The headend and tailend routers of the tunnel must have a BGP relationship.
• They are run over Ethernet cores only.
• They use RSVP to provide bandwidth for the tunnel.
• They require EIGRP to be running in the core.

What is true of MPLS TE?

MPLS TE allows the MPLS-enabled network to replicate and expand upon the TE capabilities of Layer 2 ATM and Frame Relay networks. MPLS uses the reachability information provided by Layer 3 routing protocols and operates like a Layer 2 ATM network.

Which is better MPLS or VPN?

VPN vs MPLS: Which One to Choose? For example, If your company is running critical, real-time applications across the network (such as voice, video or remote desktop), MPLS is a perfect solution. While VPN is suitable for those who want to save cost and has low request for QoS, speed, etc.
