We will put the link London/Amsterdam in service first.
We will also have a loop Roubaix/London/Amsterdam/Roubaix.
And we will test with this maintenance the redundancy of the network :)

Maintenance has started on the 25 July at midnight.

We forced the disconnection of the link London/Roubaix in order to to check the good routing function via Amsterdam.
It works properly.

Besides vss-2 and vss-1 support very badly the routing changing. the BGP takes 100% of CPU during a very long time and the ARP process is not responding to all requests. Suddenly, machines behind vss-1 and vss-2 did not find the MAC of the router and did no longer ping. It is a chronic problem that Cisco could not fix. We will try other solutions.

We have modified routers' setting at Roubaix in order to fix the problem waiting meanwhile the arriving of ASR.

Done.

The traffic is rerouted directly via roubaix/london.

One of the xenpack in rbx-1 is dead. We are replacing it.
