# srl-mpls-iot
MPLS interop with SROS and VMX
## Installation steps
* Clone [vrnetlab](https://github.com/hellt/vrnetlab)
* Copy Junos VMX .tgz image to vrnetlab/vmx and run 'make' in that directory -> produces vrnetlab/vr-vmx
* Copy SROS .qcow2 image to vrnetlab/sros and name it like sros-vm-\.qcow2 -> produces vrnetlab/vr-sros:21.7.R2
[Update Linux kernel to 5.x](https://computingforgeeks.com/install-linux-kernel-5-on-centos-7/)
## Networking
Before using docker-compose to bring up netbox, add the following:
```
networks:
default:
driver: bridge
external: true
name: clab
```
This ensures the netbox containers are connected to the Containerlab bridge
## Populating Netbox
[Netbox agent](https://github.com/Solvik/netbox-agent) is a Python based tool for automatically populating Netbox with device inventory information.
```
pip3 install netbox-agent
```
To test, register the local server with Netbox (after creating a token):
```
python3 -m netbox_agent.cli --register --netbox.url http://localhost:8000 --netbox.token x --update-all
```
There is a script to populate device types:
```
scripts/populate_netbox_device_types.py --vendors nokia
```
## Adding files to SROS qcow2 image
For example: a license file or Python packages
```
guestfish --rw -a ./sros-vm-21.7.R2.qcow2 -m /dev/sda1 copy-in ./sros.license /
```
```
guestfish --rw -a ./sros-vm-21.7.R2.qcow2 -m /dev/sda1 copy-in /usr/local/lib/python3.6/site-packages/pynetbox /
```
# PySROS demo
SROS can now execute Python scripts, for example:
```
A:admin@dcgw1# pyexec tftp://172.31.255.29/pysros-demo.py
dcgw1
```
The setup uses vrnetlab VMs which run a TFTP server inside the container hosting the SROS VM. Each VM has the same IP
## Fixing TCP offload
For some reason Netbox containers cannot talk to SRL nodes, tcpdump shows checksum errors. To fix:
```
containerlab tools disable-tx-offload -c netbox-docker_netbox_1
```
## gNMI towards SROS nodes
After configuring AAA profiles following [this snippet](https://github.com/nokia/SROS-grpc-services#user-access-profile-and-authorization), we can make gNMI queries:
```
gnmic -a clab-mpls-iot-lab-dcgw1 -u grpc -p super_secret\! -e json_ietf --insecure get --path /
```
Similarly, for Junos:
```
gnmic -a clab-mpls-iot-lab-vmx1 -u admin -p admin@123 -e json_ietf --insecure get --path /
```
## Netbox onboarding plugin
At https://github.com/networktocode/ntc-netbox-plugin-onboarding there is an onboarding plugin that could be added as another means to operationalize SROS devices quickly,
see https://github.com/netbox-community/netbox-docker/wiki/Using-Netbox-Plugins on how to add
