Building your own FRRouting Snap

(Tested on Ubuntu 16.04 with Snap Version 2, does not work on Ubuntu 15.x which uses earlier versions of snaps)

1. Install snapcraft:

   sudo apt-get install snapcraft
   

2. Checkout FRRouting under a unpriviledged user account

   git clone https://github.com/frrouting/frr.git
   cd frr
   

3. (Optional) Add extra version information to snapcraft/extra_version_info.txt. Information in this file will be displayed with the frr.version command (simple cat after the display of the zebra --version output)

4. Run Bootstrap and make distribution tar.gz

   ./bootstrap.sh
   ./configure --with-pkg-extra-version=-MySnapVersion
   make dist
   

   Note: configure parameters are not important for the Snap building, except the with-pkg-extra-version if you want to give the Snap a specific name to mark your own unoffical build

   This will build frr-something.tar.gz - the distribution tar and the snapcraft/snapcraft.yaml with the matching version number

5. Create snap

   cd snapcraft
   snapcraft
   

   You should now end up with frr_something.snap

Installing the snap

(This can be done on a different system)

1. Install snapd

   sudo apt-get install snapd
   

2. Install self-built frr snap. (--force-dangerous is required to install a unsigned self-built snap)

   snap install --force-dangerous ./frr*.snap
   

   Connect the priviledged network-control plug to the snap:

   snap connect frr:network-control core:network-control
   

See README.usage.md for more details on setting up and using the snap

DONE.

The Snap will be auto-started and running.

Operations

FRRouting Daemons

At this time, all FRRouting daemons are auto-started.

A daemon can be stopped/started with (ie ospf6d)

systemctl stop snap.frr.ospf6d.service
systemctl start snap.frr.ospf6d.service

or disabled/enabled with

systemctl disable snap.frr.ospf6d.service
systemctl enable snap.frr.ospf6d.service

FRRouting Commands

All the commands are prefixed with frr.

frr.vtysh       -> vtysh
frr.version     -> Just gives version output (zebra --version)
frr.readme      -> Returns simple README with hints on using FRR

frr.bgpd-debug  -> Directly start each daemon (without service)
frr.isisd-debug
frr.ospf6d-debug
frr.ospfd-debug
frr.pimd-debug
frr.ripd-debug
frr.ripngd-debug
frr.ldp-debug
frr.zebra-debug
frr.pimd-debug
frr.nhrpd-debug
frr.babeld-debug
frr.eigrpd-debug
frr.pbrd-debug
frr.staticd-debug
frr.bfdd-debug
frr.fabricd-debug

vtysh can be accessed as frr.vtysh (Make sure you have /snap/bin in your path). If access as vtysh instead of frr.vtysh is needed, you can enable it via a snap alias as follows:

sudo snap alias frr vtysh

This will add the vtysh command to your /snap/bin for direct access. The output of

sudo snap aliases

should list vtysh command alias as enabled:
