BGP-PCEP

Overview

BGP Plugin

The OpenDaylight controller provides an implementation of BGP (Border Gateway Protocol), which is based on RFC 4271) as a south-bound protocol plugin. The implementation renders all basic BGP speaker capabilities, including:

Inter/Intra-AS peering * Routes advertising * Routes originating * Routes storage

The plugin’s north-bound API (REST/Java) provides to user:

  • Fully dynamic run-time standardized BGP configuration

  • Read-only access to all RIBs

  • Read-write programmable RIBs

  • Read-only reachability/link-state topology view

PCEP Plugin

The OpenDaylight Path Computation Element Communication Protocol (PCEP) plugin provides all basic service units necessary to build-up a PCE-based controller. Defined by RFC 8231, PCEP offers LSP management functionality for Active Stateful PCE, which is the cornerstone for majority of PCE-enabled SDN solutions. It consists of the following components:

  • Protocol library

  • PCEP session handling

  • Stateful PCE LSP-DB

  • Active Stateful PCE LSP Operations

Behavior/Feature Changes

pcep-topology-provider now allows PCEP capabilities, TLS configuration as well as PCEP timer proposals to be configured on a per-topology basis rather than being global settings.

Rarely-used configuration knobs for PCEP auto-bandwidth and segment-routing extensions have been migrated from the datastore to OSGi Configuration Admin properties.
