Question 1/124
BGP Link State (BGP-LS) introduces a new NLRI into BGP. The NLRI carries link, node, topology prefix, and other information, and is also referred to as the link state NLRI.
Correct Answer: A
Understanding BGP Link State (BGP-LS)
#What is BGP-LS?
BGP-LS (BGP Link-State)is anextension of BGPthat allows routers to exchangenetwork topology informationviaLink-State NLRI.
HelpsSDN controllers and path computation elements (PCEs)makeintelligent routing decisions.
#What Does BGP-LS Advertise?
#Node Information- Router IDs, Loopbacks
#Link Information- Bandwidth, Delay, Cost
#Prefix Information- Network Subnets
#Topology Information- Full network graph
Why is the Answer TRUE?
#BGP-LS introduces a new NLRI formatfor advertising link-state information.
#NLRI (Network Layer Reachability Information) is used to distribute topology datato SDN controllers.
#It improves path optimization by enabling centralized traffic engineering decisions.
Real-World Application:
SDN-Based Traffic Engineering:Used inSegment Routing (SR)networks for centralizedpath selection.
MPLS TE (Traffic Engineering):Optimizes network paths dynamically based onreal-time link-state data.
