ETCP IP and Transport Networks

Question 1

Which routing protocol is most commonly used for inter-domain routing in Ericsson transport network deployments?

Accepted Answer

BGP

Answer

BGP (Border Gateway Protocol) is the standard inter-domain routing protocol used between autonomous systems in transport networks.

Question 2

In Ericsson's IP/MPLS transport, what does LSP stand for?

Accepted Answer

Label Switched Path

Answer

LSP stands for Label Switched Path, the end-to-end path established through an MPLS network for forwarding labeled packets.

Question 3

What is the primary purpose of MPLS Traffic Engineering (TE) in Ericsson transport networks?

Accepted Answer

Optimizing bandwidth utilization across network paths

Answer

MPLS-TE allows operators to optimize bandwidth by directing traffic along specific paths rather than relying solely on shortest-path routing.

Question 4

Which Ericsson router platform is designed for high-capacity IP/MPLS core network deployments?

Accepted Answer

Ericsson Router 6000

Answer

The Ericsson Router 6000 series is purpose-built for high-capacity core and edge IP/MPLS deployments.

Question 5

What does QoS DSCP marking do in an Ericsson IP transport network?

Accepted Answer

Marks packets to indicate their priority for handling

Answer

DSCP (Differentiated Services Code Point) marks packets in the IP header so network nodes can apply appropriate priority treatment.
