Quick Start

Requires Python 3.9+. More detailed instructions and install options can be found here.

Package Install

Grab the latest deb/rpm from releases.

This will install vnoded/vcmd, system dependencies, and CORE within a python virtual environment at /opt/core/venv.

sudo <yum/apt> install -y ./<package>

Then install OSPF MDR from source:

git clone https://github.com/USNavalResearchLaboratory/ospf-mdr.git
cd ospf-mdr
./bootstrap.sh
./configure --disable-doc --enable-user=root --enable-group=root \
  --with-cflags=-ggdb --sysconfdir=/usr/local/etc/quagga --enable-vtysh \
  --localstatedir=/var/run/quagga
make -j$(nproc)
sudo make install

Script Install

The following should get you up and running on Ubuntu 22.04. This would install CORE into a python3 virtual environment and install OSPF MDR from source.

git clone https://github.com/coreemu/core.git
cd core
# install dependencies to run installation task
./setup.sh
# run the following or open a new terminal
source ~/.bashrc
# Ubuntu
