## About
The Common Open Research Emulator (CORE) is a tool for emulating
networks on one or more machines. You can connect these emulated
networks to live networks. CORE consists of a GUI for drawing
topologies of lightweight virtual machines, and Python modules for
scripting network emulation.

## Quick Start
Requires Python 3.9+. More detailed instructions and install options can be found
[here](https://coreemu.github.io/core/install.html).

### Package Install
Grab the latest deb/rpm from [releases](https://github.com/coreemu/core/releases).

This will install vnoded/vcmd, system dependencies, and CORE within a python
virtual environment at `/opt/core/venv`.
```shell
sudo <yum/apt> install -y ./<package>
```

Then install OSPF MDR from source:
```shell
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](https://github.com/USNavalResearchLaboratory/ospf-mdr) from source.

```shell
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
inv install
# CentOS
inv install -p /usr
```
