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

The configuration knob for pcep-provider’s timer has been moved into pcep-topology configuration. Users relying on non-default value need to update their configuration.

New Features

The Graph functionality has been extended to handle multiple PCEP topologies.

Deprecated Features

No deprecated features.
