DANOS 2012 ships with FRR 7.4 and pre-release testing was performed against 7.4

We have prepared a version of FRR 7.5 for use in DANOS which includes a number of backported fixes and enhancements. These patches are upstream and should be included in the FRR 7.6 release, which we hope to include in the next version of DANOS due later in 2021.

The below guide is intended as an aid for users who wish to build and install FRR 7.5 on DANOS 2012.

  1. Clone danos/vyatta-protocols-frr, checking out version 1.15.0:

$ git clone https://github.com/danos/vyatta-protocols-frr.git -b debian/1.15.0

danos/frr, checking out the danos/7.5 branch:

$ git clone https://github.com/danos/frr.git -b danos/7.5

danos/vyatta-route-broker, checking out version 1.0.3:

$ git clone https://github.com/danos/vyatta-route-broker.git -b debian/1.0.3

and CESNET/libyang, checking out the debian/master branch:

2. Build the new packages, using Building a package from source as a reference. The easiest way to build our packages is with the danos-buildpackage tool, particularly if you are not already familiar with building Debian packages.

Note: depending on your Docker setup, you may need to execute danos-buildpackage as root eg. using sudo.

After running the above builds, the current directory should now contain a large number of deb packages.

3. Transfer the required packages to your DANOS instance, eg. using scp.

Note: we don’t need all the packages which were built.

4. Log in to your DANOS instance, and optionally back up your current “stock” 2012 image

You can choose this backed up image at the bootloader if you wish to return to FRR 7.4.

5. Install the new packages on your running DANOS image

6. Reboot - you are now running FRR 7.5!

The output of show version should now look something like:
