Explains how SRv6 locators organize SID address spaces for routing and traffic steering and describes locator deployment and lightweight host routing through LLDP.
This chapter focuses on SRv6 locators, which are fundamental IPv6 address prefixes used to identify blocks of Segment Identifiers within an SRv6 network. It examines the structure and various types of locators, including Base Format, uSID, and Anycast locators, and discusses their specific applications and limitations.
Starting from Release 26.3.1, this chapter covers Lightweight host routing using LLDP. This feature simplifies host reachability in SRv6 fabric deployments by allowing hosts or hypervisors to advertise IPv6 prefixes or SRv6 locators directly to a connected Leaf router, eliminating the need to run a full routing protocol stack on the host.
SRv6 Locators
Explains how SRv6 locators organize SID address spaces and provide the addressing structure required for SID allocation, routing, and forwarding within an SRv6 domain.
Limitations for locators
Identifies the format, scale, advertisement, protection, and Flex-Algo limitations that must be considered when deploying uSID and anycast locators.
Configure SRv6 locators
Explains how to configure SRv6 locators that define IPv6 address spaces and provide the foundation for SID allocation, routing, and traffic forwarding.
Lightweight host routing using LLDP
Explains how hosts and hypervisors advertise IPv6 prefixes or SRv6 locators through LLDP and describes the operational requirements, restrictions, and configuration process.
