Understanding SRv6 (Segment Routing over IPv6) Policies
# What is an SRv6 Policy?
* A traffic engineering (TE) mechanism used in SRv6-enabled networks.
* Defines a set of Segment Routing (SR) paths that direct packets through a predefined set of waypoints.
* Uses SRv6 SIDs (Segment Identifiers) instead of MPLS labels.
# How Can SRv6 Policies Be Configured?# Static SRv6 Policy Configuration:
* Manually configured by network administrators.
* Used in predictable, fixed network paths.
# Dynamic SRv6 Policy Generation:
* Created dynamically by an SDN controller (e.g., Huawei iMaster NCE).
* The controller analyzes network conditions and adjusts paths automatically based on traffic load and link failures.
Why is the Answer TRUE?
# SRv6 policies can be configured manually or dynamically delivered by a controller.# SDN-based SRv6 solutions improve network automation and traffic engineering efficiency.
Real-World Application:
* Cloud Data Centers: Uses dynamic SRv6 policies for optimal traffic distribution.
* 5G Transport Networks: Uses SRv6 TE for low-latency service guarantees.
