EOS is now based on AlmaLinux 9. The document outlines the EOS image base operating system (OS) transition from CentOS 7 to AlmaLinux 9. With CentOS 7 reaching its end of life (EOL) in June 2024 and the impending cessation of active support for CentOS Stream 8 in May 2024, It was decided to migrate directly to a RHEL 9 compatible base for EOS skipping RHEL 8/CentOS 8. EOS 4.32.0 is based on AlmaLinux 9 which is binary compatible with RHEL 9.

Segment Routing provides mechanism to define end-to-end paths within a topology by encoding paths as sequences of sub-paths or instructions. These sub-paths or instructions are referred to as “segments”. IS-IS Segment Routing (henceforth referred to as IS-IS SR) provides means to advertise such segments through IS-IS protocol.

The Label Distribution Protocol (LDP) is a protocol in the Multiprotocol Label Switching (MPLS) context that allows label switch routers (LSRs) to exchange label mapping information. It is a distributed protocol without a central controller. Instead, each LSR generates local label mappings for Forward Equivalence Classes (FECs) and propagates this information to adjacent LSRs which it maintains LDP sessions with.
