Using the FRRouting Snap
===============================
After installing the Snap, the priviledged plug need to be connected:
snap connect frr:network-control core:network-control
Enabling/Disabling FRRouting Daemons
-------------------------------------------
By default (at this time), all FRRouting daemons will be enabled
on installation. If you want to disable a specific daemon, then use
the systemctl commands
ie for `ospf6d` (OSPFv3):
systemctl disable snap.frr.ospf6d.service
systemctl enable snap.frr.ospf6d.service
The daemons are: `ripd`, `ripngd`, `ospfd`, `ospf6d`, `isisd`, `bgpd`,
`pimd`, `zebra`
Commands defined by this snap
-----------------------------
- `frr.vtysh`:
FRRouting VTY Shell (configuration tool)
- `frr.version`:
Returns output of `zebra --version` to display version and configured
options
- `frr.readme`:
Returns this document `cat README_usage.md`
- `frr.set`:
Allows to enable `FPM` module. See FPM section below
and for debugging defined at this time (May get removed later - do not
depend on them). These are mainly intended to debug the Snap
- `frr.zebra-debug`:
Starts zebra daemon in foreground
- `frr.ripd-debug`:
Starts ripd daemon in foreground
- `frr.ripngd-debug`:
Starts ripng daemon in foreground
- `frr.ospfd-debug`:
Starts ospfd daemon in foreground
- `frr.ospf6d-debug`:
Starts ospf6d daemon in foreground
- `frr.isisd-debug`:
Starts isisd daemon in foreground
- `frr.bgpd-debug`:
Starts bgpd daemon in foreground
- `frr.pimd-debug`:
Starts pimd daemon in foreground
- `frr.ldpd-debug`:
Starts ldpd daemon in foreground
MPLS (LDP)
----------
The MPLS forwarding requires a Linux Kernel version 4.5 or newer and
specific MPLS kernel modules loaded. It will be auto-detected by
FRR. You can check the detected setup with the `show mpls status`
command from within `frr.vtysh`
The following kernel modules `mpls-router` and `mpls-iptunnel`
need to be loaded. On Ubuntu 16.04, this can be done by editing
'/etc/modules-load.d/modules.conf' and add the following lines:
# Load MPLS Kernel Modules
mpls-router
mpls-iptunnel
For other distributions, please check the documentation on loading
modules. You need to either reboot or use `modprobe` to manually load
the modules as well before MPLS will be available.
In addition to this, the MPLS Label-Processing needs to be enabled
with `sysctl` on the required interfaces. Assuming the interfaces
are named `eth0`, `eth1` and `eth2`, then the additional lines in
`/etc/sysctl.conf` will enable it on a Ubuntu 16.04 system:
# Enable MPLS Label processing on all interfaces
net.mpls.conf.eth0.input=1
net.mpls.conf.eth1.input=1
net.mpls.conf.eth2.input=1
net.mpls.platform_labels=100000
These settings require either a reboot or a manual configuration with
`sysctl` as well.
FPM Module
----------
The `frr.set` allows to turn FPM module on or off.
frr.set fpm {disable|protobuf|netlink}
Disables FPM or enables FPM with selected mode
By default, the FPM module is disabled, but installed with netlink and
protobuf support. To enable the FPM module, use the `frr.set fpm protobuf`
or `frr.set fpm netlink` command. The command will only enable the mode
for the next restart of zebra. Please reboot or restart zebra after
changing the mode to become effective.
FAQ
---
- frr.vtysh displays `--MORE--` on long output. How to suppress this?
- Define `VTYSH_PAGER` to `cat` (default is `more`). (Ie add
`export VTYSH_PAGER=cat` to the end of your `.profile`)
- ospfd / ospf6d are not running after installation
- Installing a new snap starts the daemons, but at this time they
may not have the required priviledged access. Make sure you
issue the `snap connect` command as given above (can be verified
with `snap interfaces`) and **THEN** restart the daemons (or
reboot the system).
This is a limitation of any snap package at this time which
requires priviledged interfaces (ie to manipulate routing tables)
