How to Build VyOS 1.2 with frr


I want to build the latest VyOS version using vyos-frr instead of quagga as even following the instructions from the wiki on Debian Jessie.

However, the latest build still has quagga and I do not get frr daemon as given in the blog post:

Kindly provide instructions/changes to the build process to enable frr while building VyOS image from sources. The advantage of this build is that isisd can be enabled and can be used through vtysh in the iso provided in the blog post.


I tried to build it myself by adding vyos-frr submodule. However I got conflicts with vyatta-quagga_0.99.20.1-14+vyos2+current1_amd64.deb package.

Here are the error logs:

Selecting previously unselected package vyatta-quagga.

dpkg-deb: error: subprocess paste was killed by signal (Broken pipe)

And at the end:

The iso partially built is unusable as it is a symbolic link:
vyos-999.201801121149-amd64.iso -> /home/user/New/vyos-build/build/live-image-amd64.hybrid.iso

Can anyone suggest steps to resolve?
