Workflow:

- Assuming that you have a public network already setup

    - Enable that network to be External

        - neutron net-update public —router:external=True
- Create a test network

    - neutron net-create test

Contrail database backup/restore procedure

This procedure can be used to backup contrail database (except the ContrailAnalytics keyspace) during upgrade from R2.20#64 to R2.22.1#5. Incase of database corruption during the upgrade process, the backed up database can be restored on the cluster. The below procedure can be used to backup/restore contrail database except the ContrailAnalytics keyspace.

1.1	Dropping ContrailAnalytics keyspace before upgrade

If the user prefers to drop the ContrailAnalytics data before upgrading the cluster, then the following can be done:


From FAB_NODE, execute “fab stop_collector”

Contrail Upgrade procedure – Minimal downtime

Upgrade procedure to minimize downtime in the production network. Upgrade controller and compute separately. The procedure is based on fab upgrade_contrail.

1. Workaround for the bug (https://bugs.launchpad.net/juniperopenstack/+bug/1506634 )

Create policy to deny stop/start of services during upgrade

fab -R control -- 'echo "#! /bin/sh" > /usr/sbin/policy-rc.d'

Step 1: Enable tunnel services
for example: for an mx480 with two fpcs for redundant logical tunnels
fpc 1 {
    pic 0 {
        tunnel-services;
        inline-services {
            bandwidth 10g;
        }
    }
    pic 1 {
