IMPORTANT: for Nokia SR Linux, use kind "srl" and type "ixr6"

## Download and install the latest release
$ sudo bash -c "$(curl -sL https://get.containerlab.dev)" -- -v 0.41.2

## Deploy proposed two SR node scenario
$ cd ~/tfs-ctrl/hackfest/containerlab
$ sudo containerlab deploy --topo tfs-scenario.clab.yml

## Access SR Bash
$ docker exec -it clab-tfs-scenario-srl1 bash

## Acess SR CLI
$ docker exec -it clab-tfs-scenario-srl1 sr_cli

## Destroy scenario
$ sudo containerlab destroy --topo tfs-scenario.clab.yml

## Install gNMIc
$ sudo bash -c "$(curl -sL https://get-gnmic.kmrd.dev)"

## gNMI Capabilities request
$ gnmic -a clab-srlinux-srl1 -u admin -p NokiaSrl1! --skip-verify capabilities

## gNMI Get request
$ gnmic -a clab-srlinux-srl1 -u admin -p NokiaSrl1! --skip-verify -e json_ietf get --path /system/name/host-name
$ gnmic -a clab-srlinux-srl1 -u admin -p NokiaSrl1! --skip-verify -e json_ietf get --path /interface[name=mgmt0]

## gNMI Set request
$ gnmic -a clab-srlinux-srl1 -u admin -p NokiaSrl1! --skip-verify -e json_ietf set --update-path /system/name/host-name --update-value slr11

(we check the changed value) 
$ gnmic -a clab-srlinux-srl1 -u admin -p NokiaSrl1! --skip-verify -e json_ietf get --path /system/name/host-name 

## Subscribe request
$ gnmic -a clab-srlinux-srl1 -u admin -p NokiaSrl1! --skip-verify -e json_ietf subscribe --path /interface[name=mgmt0]/statistics
(In another terminal, you can generate traffic) 
$ssh admin@clab-srlinux-srl1


## Enable OpenConfig data models and set as default:
$ docker exec -it clab-tfs-scenario-srl1 sr_cli
# enter candidate
# system management openconfig admin-state enable
# system gnmi-server network-instance mgmt yang-models openconfig
# commit stay
# quit


# Check configurations done:
gnmic -a 172.100.100.101 -u admin -p NokiaSrl1! --skip-verify -e json_ietf get --path '/network-instances' > srl1-nis.json
gnmic -a 172.100.100.101 -u admin -p NokiaSrl1! --skip-verify -e json_ietf get --path '/interfaces' > srl1-ifs.json
