BGP (S)ecure (R)outing E(x)tension Software Suite

The NIST BGP Secure Routing Extension (NIST-BGP-SRx) is an open-source reference implementation and research platform for investigating emerging BGP security extensions and supporting protocols such as RPKI Origin Validation and BGPsec Path Validation.

Additional information can be found at the BGP-SRx Software Page and the latest publication BGP Secure Routing Extension (BGP-SRx): Reference Implementation and Test Tools for Emerging BGP Security Standards based on NIST-BGP-SRx version 5.

Please read the NIST disclaimer regarding the software of this project, the information it provides and the other resources it uses. Note that these software prototypes are expressly provided as is and are intended for research and development purposes only.

Project Status

The project contains two major versions:

• version 6 which is the current version providing BGPsec path validation (BGP-PV), BGP origin validation (BGP-OV) and ASPA validation (BGP-AV).

• version 5 only contains BGP-PV and BGP-OV.

Version 6 provides an overhaul of the QuaggaSRx policy processing by separating BGP-PV and BGP-OV as well as adding ASPA validation (BGP-PV). This version is the preferred version available in the master branch.

To view a complete list of the NIST BGP-SRx capabilities see the CAPABILITIES file.

Branching

The main branch of the repository will deliver NIST-BGP-SRx version 6. Branch:

• master: This branch provides the current recommended version of NIST-BGP-SRx (version6.3). This version is updated to be used with Rocky 9 and contains ASPA validation and a complete re-write of the Quagga-SRx policy scripting and processing for BGP-OV, BGP-PV, and BGP-AV. The ASPA implementation in BGP-SRx incorporates the algorithms for ASPA-based upstream and downstream AS path verifications. It is our understanding that while the style of describing these algorithms may have changed, they have remained unchanged in their function in draft versions 10 through 18 (https://datatracker.ietf.org/doc/html/draft-ietf-sidrops-aspa-verification-18 ). So, our implementation of the algorithms is consistent with draft version-18. Our code includes the basic cases of customer-to-provider, lateral peer, and provider-to-customer peering relationships. We have not coded the specialized cases such as those involving route server (RS), mutual-transit, or complex relations.
• version5: This branch stands on its own and is only maintained for BUG fixes. New features are added to the master branch which is contains NIST-BGP-SRx Version 6.
• pre-release-6 (deprecated): This branch was a "sneak preview" of the upcoming version 6 and is not further maintained and expected to be removed in the future.

Testing

The software was continuously tested during development. We performed interoperability test and published them at IETF SIDR meetings as well as IETF SIDROPS meetings. The codebase itself provides a simple testing to test basic functionality. The development up to version 6.2.0 was done using CentOS 7 though we compiled the project on CentOS 8. Starting with version 6.3.0 the development was performed on linux Rocky 9. Each release was successfully build and tested using the build script and test suite provided.

Unit Test

BGP-SRx consists of four semi-independent components. Semi-independent only because some components such as the srx-crypto-api and srx-server do provide API's for other components within the package. The development though is performed separately.

For this reason, each component will have its own unit tests if at all. These will if available be located within the appropriate source folder or the newly added EXAMPLES project which will be installed in <install-root>/opt/bgp-srx-examples. Please consult the README files located in each component directory for more information.

Performance Test

The software was tested throughout the development and multiple publications are available regarding performance testing. Please visit the BGP-SRx Software Page for more information.

Getting Started

This project archive provides a "buildBGP-SRx.sh" shell script for an easy sandbox installation. This script allows to have the software installed within the code folder.

The codebase itself contains multiple components.

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes. See Installing for notes on how to deploy the project on a live system.

Prerequisites

The CONTENT file contains the most recent requirements for the build.

Building & Installing

Building and installation is explained in detail in the INSTALL.md file.

This software suite provides the following list of modules:

• SCA: SRx Crypto API (provides cryptographic capabilities)
• SRxSnP: SRx-Server and SRx-Proxy (the validation server and proxy)
• QSRx: Quagga SRx (the routing engine)
• BIO: BGPsec traffic generator and crypto module tester.
• EXAMPLES: Examples, test scripts, and test framework generators (TFG) to test BGP-SRx modules.

Two more implementations are available ExaBGPsec and GoBGPsec. More information on then can be found in the CAPABILITIES file.

The newest addition is the Test Framework Generator for ASPA (TFG-ASPA). It is part of the EXAMPLES module. More information on the TFG-ASPA can be found in the TFGA-ASPA README.MD file.

Quick Functional Test / Demo

The BGP-SRx software suite does provide a test system integrated in the build
script. The script does test proper functionality of the srx-crypto-api as well as the integration into BGPsec-IO.

Furthermore BGP-SRx provides a complete set of examples, demos which are in the examples folder but will be compiled for the host system using the buildBGP-SRx.sh script. The examples will be installed in the folder opt/bgp-srx-examples/ folder. Each example does have its own example starter script which allows to easily start all needed components either using the screen tool (default) or the gnome-terminal using -t. Furthermore, the test folders contain an appropriate run/sh script. All scripts provide a help which will be printed by using the -? switch.

Docker Running Examples

In order to edit QuaggaSRx, SRx Server and RPKI-Rtr server's configuration files in detail, please refer to each example file within the example directories.

Generate Docker image

To generate docker image, you need to run 'docker build' command with the Docker file

docker build -f <docker file> -t <docker image name> <path>

In our example,

docker build -t nist/bgp-srx .  (Don't forget '.' at the end)

• Staring the RPKI Cache Test Harnes (rpkirtr_svr)

1. Create the configuration file for the RPKI Cache Test Harnes: rpkirtr_svr.conf

  echo "add 10.0.0.0/8 9 7675" > ./rpkirtr_svr.conf

2. Start the docker container for rpkirtr_svr instance

  docker run --rm -it --name rpkirtr_server \
         -v $PWD/./rpkirtr_svr.conf:/usr/etc/rpkirtr_svr.conf \
         -p 323:323 \
         nist/bgp-srx \
         rpkirtr_svr -f /usr/etc/rpkirtr_svr.conf

Or run a rpkirtr_svr instance with a pre-defined configuration

  docker run --rm -it --name rpkirtr_server \
         -v <location/user-defined/rpkirtr_svr.conf:/usr/etc/rpkirtr_svr.conf \
         -p 323:323 \
         nist/bgp-srx \
         rpkirtr_svr -f /usr/etc/rpkirtr_svr.conf

• Starting the SRx Server

1. Identify the IP address of the RPKI Cache Test Harness rpkirtr_svr

  docker inspect --format '{{ .NetworkSettings.IPAddress }}' <container name>

Here:

  docker inspect --format '{{ .NetworkSettings.IPAddress }}' rpkirtr_server

  Example Result: 172.17.0.2

Using the retrieved IP address, configure the SRx Server instance to point ot the RPKI Cache Test Harness. Here replace 172.17.0.2 with the IP address retrieved prior.

  sed "s/localhost/172.17.0.2/g" ./srx-server/src/server/srx_server.conf > /tmp/srx_server.conf

Now start the SRx Server srx_server docker container.

  docker run --rm -it --name srx_server \
         -v /tmp/srx_server.conf:/usr/etc/srx_server.conf \
         -v $PWD/./examples/bgpsec-keys/:/usr/opt/bgp-srx-examples/bgpsec-keys \
         -p 17900:17900 -p 17901:17901 \
         nist/bgp-srx \
         srx_server -f /usr/etc/srx_server.conf

Or use our pre-defined keys and config files in the example directories

  docker run --rm -it --name srx_server \
         -v </location/user-defined/srx_server.config>:/usr/etc/srx_server.conf  \
         -v </location/user-defined/keys/>:/usr/opt/bgp-srx-examples/bgpsec-keys \
         -p 17900:17900 -p 17901:17901 \
         nist/bgp-srx \
         srx_server -f /usr/etc/srx_server.conf

• Starting QuaggaSrx

First gather the IP address for the SRx Server instance as described earlier and add modify the quagga configuration.

docker inspect --format '{{ .NetworkSettings.IPAddress }}' srx_server

Example result: 172.17.0.3

Use the learned IP address and update the QuaggaSRx configuration

sed "s/srx connect/srx connect 172.17.0.3 17900/g" ./quagga-srx/bgpd/bgpd.conf.sampleSRx > /tmp/bgpd.conf

Finally start the QuaggaSRx server

  docker run --rm -it --name quaggasrx \
         -v /tmp/bgpd.conf:/usr/etc/bgpd.conf \
         -v $PWD/./examples/bgpsec-keys/:/usr/opt/bgp-srx-examples/bgpsec-keys \
         -p 179:179 -p 2605:2605 \
         nist/bgp-srx \
         bgpd -f /usr/etc/bgpd.conf

Or use pre-defined keys and config files in our example directories

  docker run --rm -it --name quaggasrx \
         -v </location/user-defined/quagga.config>:/usr/etc/bgpd.conf  \
         -v </location/user-defined/keys/>:/usr/opt/bgp-srx-examples/bgpsec-keys \
         -p 179:179 -p 2605:2605 \
         nist/bgp-srx \
         bgpd -f /usr/etc/bgpd.conf  

• Docker compose

Docker Compose allows to define and run multi-container Docker applications. With Compose, you use a YAML file to configure your application’s services. Then, with a single command, you create and start all the services from your configuration.

The following command will execute all three docker containers in the docker-compose.yml file.

docker-compose up

To stop and remove containers, simply Ctrl-C twice or

docker-compose down
