How to Specify the Routing Instance in Python 3 Applications on Devices Running Junos OS Evolved
Understanding the libpyvrf Module
A routing instance is a collection of routing tables, interfaces,
and routing protocol parameters. Each routing instance has a unique
name and a corresponding IP unicast table, which can be used to separate
traffic for that instance from other traffic. For example, on devices
running Junos OS Evolved, you can enable a dedicated management virtual
routing and forwarding (VRF) instance, mgmt_junos, which
uses a separate administrative routing table dedicated to management
tasks.
Routing instances enable you to isolate traffic traversing the
network without using multiple devices to segment your network. When
you use routing instances to isolate traffic, network utilities like ping and ssh must reference
the correct routing instance in order to send traffic to a destination
that is reachable through that instance.
The Junos OS Evolved image runs natively on Linux, providing direct access to all the Linux
utilities and operations, including the Python libraries that are part of the base
image. The Python 3 library on devices running Junos OS Evolved also includes the
Juniper Networks libpyvrf module, which enables Python 3
applications that are executed in the shell to specify the routing instance to use
for specific processes and network utilities.
Table 1 outlines the libpyvrf functions that you can use in Python 3 applications
that are executed in the Linux shell. You can use the functions to
instruct a process to use a specific routing instance. If the same
process requires multiple routing instances, you can also set the
routing instance context for a specific socket, which does not affect
the context for the process itself. Packets through the socket then
use the routing table associated with that instance. When you set
the routing instance for a process or socket, the libpyvrf module sets the context to the Linux VRF that corresponds to the
Junos OS routing instance.
| Description |
|---|---|
| Return the Linux VRF corresponding to a Junos OS routing instance. |
| Return the index of the routing table associated with the specified routing instance. |
| Return the routing instance associated with the specified task. Note: This function is deprecated starting in Junos OS Evolved Release 22.1R1. |
| Return the routing instance associated with the current process. |
| Set the routing instance for the specified socket. |
| Set the routing instance for the specified process. Note: This function is deprecated starting in Junos OS Evolved Release 22.1R1. |
| Set the routing instance for the current process. |
Functions in the libpyvrf module
can raise the following exceptions depending on the function and error:
libpyvrf.error—Generated whenlibvrfreturns an error.libpyvrf.evo_not_ready—Generated when the Junos OS Evolved network stack is not ready, for example when the device is booting.libpyvrf.invalid_table—Generated when the specified routing instance or table ID is invalid.
The following sample Python script attempts to ping a host that
is only reachable through the mgmt_junos routing instance. The script initially pings the host before calling
the set_vrf() function. The script then
calls the set_vrf() function to associate
the mgmt_junos routing instance with the current process
and pings the host again.
[vrf:none] user@host:~# cat libpyvrf-ping.py
import libpyvrf as vrf
import subprocess
command = [ 'ping', '-c', '3', 'host1.example.com' ]
try:
# Ping the host before setting the routing instance
subprocess.call(command) == 0
# Set the routing instance
vrf.set_vrf("mgmt_junos")
print ("\nUsing routing instance:", vrf.get_vrf())
# Ping the host after setting the routing instance
subprocess.call(command) == 0
except vrf.invalid_table as e:
print ("Invalid Table")
except vrf.evo_not_ready as e :
print ("Junos OS Evolved network stack is not ready")
except vrf.error as e :
print ("Generic libvrf error")
When you execute the script, the first ping command fails, because
the process uses the default routing instance in this case, and the
host is only reachable through the mgmt_junos routing instance.
The second ping command, which uses the mgmt_junos routing
instance, succeeds.
[vrf:none] user@host:~# python3 libpyvrf-ping.py ping: unknown host host1.example.net Using routing instance: mgmt_junos PING host1.example.com (198.51.100.10) 56(84) bytes of data. 64 bytes from host1.example.com (198.51.100.10): icmp_seq=1 ttl=60 time=1.02 ms 64 bytes from host1.example.com (198.51.100.10): icmp_seq=2 ttl=60 time=0.672 ms 64 bytes from host1.example.com (198.51.100.10): icmp_seq=3 ttl=60 time=0.741 ms --- host1.example.com ping statistics --- 3 packets transmitted, 3 received, 0% packet loss, time 2003ms rtt min/avg/max/mdev = 0.876/0.946/1.001/0.063 ms
You can reset the routing instance back to the default routing instance association in a Python application by specifying an empty string for the routing instance name. For example:
vrf.set_vrf("")If an application does not specify a routing instance, the default
routing instance association depends on the environment of the process.
If the environment preloads the libsi.so library, then by default, the application uses the default routing
instance and table, default.inet. Otherwise, there is no
default routing instance associated with the process or sockets.
To determine if the environment preloads the libsi.so library, verify that value of the LD_PRELOAD environment variable includes the path to
the library.
[vrf:none] user@host:~# env | grep LD_PRELOAD LD_PRELOAD=libsi.so
If the LD_PRELOAD variable
does not include the libsi.so library
path, you can use the commands appropriate for your shell to add it,
for example:
[vrf:none] user@host:~# export LD_PRELOAD="/path/to/libsi.so" [vrf:none] user@host:~# env | grep LD_PRELOAD LD_PRELOAD=libsi.so
get_host_vrf_name() Function

import libpyvrf as vrf
try:
print ("mgmt_junos VRF:", vrf.get_host_vrf_name("mgmt_junos"))
print ("default VRF:", vrf.get_host_vrf_name("default"))
print ("L3VPN-1 VRF:", vrf.get_host_vrf_name("L3VPN-1"))
except vrf.invalid_table as e:
print ("Invalid Table")[vrf:none] user@host:~# python3 libpyvrf-get-host-vrf-name.py mgmt_junos VRF: mgmt_junos default VRF: vrf0 L3VPN-1 VRF: vrf52

undefined routing instance foo.
user@host> show route forwarding-table extensive table mgmt_junos Routing table: mgmt_junos.inet [Index 36738] Internet: ... Routing table: mgmt_junos.inet6 [Index 36738] Internet6: ...
[vrf:none] user@host:~# cat libpyvrf-get-table-id.py
import libpyvrf as vrf
try:
print (vrf.get_table_id("mgmt_junos"))
print (vrf.get_table_id("foo"))
except vrf.evo_not_ready as e:
print ("Junos OS Evolved network stack is not ready")
except vrf.error as e:
print ("Generic libvrf error")
