1 Using the FRRouting Snap
2 ===============================
4 After installing the Snap, the priviledged plug need to be connected:
6 snap connect frr:network-control core:network-control
8 Enabling/Disabling FRRouting Daemons
9 -------------------------------------------
11 By default (at this time), all FRRouting daemons will be enabled
12 on installation. If you want to disable a specific daemon, then use
13 the systemctl commands
15 ie for `ospf6d` (OSPFv3):
17 systemctl disable snap.frr.ospf6d.service
18 systemctl enable snap.frr.ospf6d.service
20 The daemons are: `ripd`, `ripngd`, `ospfd`, `ospf6d`, `isisd`, `bgpd`,
21 `pimd`, `ldpd`, `eigrpd`, `babeld`, `nhrpd`, `bfdd`, `zebra`
23 Commands defined by this snap
24 -----------------------------
27 FRRouting VTY Shell (configuration tool)
29 Returns output of `zebra --version` to display version and configured
32 Returns this document `cat README_usage.md`
34 Allows to enable `FPM` and/or disable RPKIi module. See Module section below
36 and for debugging defined at this time (May get removed later - do not
37 depend on them). These are mainly intended to debug the Snap
40 Starts zebra daemon in foreground
42 Starts ripd daemon in foreground
44 Starts ripng daemon in foreground
46 Starts ospfd daemon in foreground
48 Starts ospf6d daemon in foreground
50 Starts isisd daemon in foreground
52 Starts bgpd daemon in foreground
54 Starts pimd daemon in foreground
56 Starts ldpd daemon in foreground
58 Starts nhrpd daemon in foreground
60 Starts babeld daemon in foreground
62 Starts eigrpd daemon in foreground
64 Starts pbrd daemon in foreground
65 - `frr.staticd-debug`:
66 Starts staticd daemon in foreground
68 Starts bfdd daemon in foreground
72 The MPLS forwarding requires a Linux Kernel version 4.5 or newer and
73 specific MPLS kernel modules loaded. It will be auto-detected by
74 FRR. You can check the detected setup with the `show mpls status`
75 command from within `frr.vtysh`
77 The following kernel modules `mpls-router` and `mpls-iptunnel`
78 need to be loaded. On Ubuntu 16.04, this can be done by editing
79 '/etc/modules-load.d/modules.conf' and add the following lines:
81 # Load MPLS Kernel Modules
85 For other distributions, please check the documentation on loading
86 modules. You need to either reboot or use `modprobe` to manually load
87 the modules as well before MPLS will be available.
89 In addition to this, the MPLS Label-Processing needs to be enabled
90 with `sysctl` on the required interfaces. Assuming the interfaces
91 are named `eth0`, `eth1` and `eth2`, then the additional lines in
92 `/etc/sysctl.conf` will enable it on a Ubuntu 16.04 system:
94 # Enable MPLS Label processing on all interfaces
95 net.mpls.conf.eth0.input=1
96 net.mpls.conf.eth1.input=1
97 net.mpls.conf.eth2.input=1
98 net.mpls.platform_labels=100000
100 These settings require either a reboot or a manual configuration with
105 The `frr.set` allows to turn FPM module ond the RPKI module on or off.
107 frr.set fpm {disable|protobuf|netlink}
109 Disables FPM or enables FPM with selected mode (default: disabled)
111 By default, the FPM module is disabled, but installed with netlink and
112 protobuf support. To enable the FPM module, use the `frr.set fpm protobuf`
113 or `frr.set fpm netlink` command. The command will only enable the mode
114 for the next restart of zebra. Please reboot or restart zebra after
115 changing the mode to become effective.
117 frr.set rpki {enable|disable}
119 Disables or enables BGP RPKI (default: enabled)
121 By default, the RPKI module is enabled. To disable the RPKI module
122 use the `frr.set rpki disable` command. The command will only enable
123 the module after the next restart of the bgp daemon. Please reboot or
124 restart bgpd after changing the mode to become effective.
125 (Normally, there is no need to disable the module as it has no effect
126 if there are no RPKI configurations in BGP)
130 - frr.vtysh displays `--MORE--` on long output. How to suppress this?
131 - Define `VTYSH_PAGER` to `cat` (default is `more`). (Ie add
132 `export VTYSH_PAGER=cat` to the end of your `.profile`)
134 - bfdd / ospfd / ospf6d / nhrpd are not running after installation
135 - Installing a new snap starts the daemons, but at this time they
136 may not have the required privileged access. Make sure you
137 issue the `snap connect` command as given above (can be verified
138 with `snap interfaces`) and **THEN** restart the daemons (or
140 This is a limitation of any snap package at this time which
141 requires privileged interfaces (ie to manipulate routing tables)
143 - Can I run vtysh directly without the "frr." prefix?
144 - Yes, enable the vtysh alias in the frr snap package by:
145 sudo snap alias frr vtysh
