Jinja2 template for Ansible

Quick howto

  1. Install Ansible, I use latest ubuntu. The official installation guide is here
  2. Modify /etc/ansible/hosts to include: localhost ansible_connection=local
  3. Clone this repository
  4. Modify roles/gre/vars/main.yml to match your setup
  5. Execute ansible-playbook playbook.yml
  6. Configuration files named hostname.cfg will be generated in /tmp, you can modify the path in roles/gre/tasks/main.yml

The template itself is located in roles/gre/templates. You can use this for autogenerating configuration files based on your requirements.

By default files are placed in /tmp

Where to apply a generated route-policy

router bgp 65201
 bgp router-id 10.3.117.162
 address-family vpnv4 unicast
 !
 neighbor 192.168.72.7
  remote-as 65201
  update-source Loopback1
  address-family vpnv4 unicast
   route-policy fake-nh in

Route policy to filter out anything but default

tbd route-map default-only

Creating computes section based on list

awk 'BEGIN {count=100;print "computes:"} {count++;print "  - number: "count"\n    name: "$1"\n    ip: "$2"\n    fake_ip: 169.254.33."count}' computes

cat computes
compute-6-2 10.1.0.96
