Main CDS router failed and replaced.
Nyath, Dave, Jonathan, Erik,

At around  19:14 UTC the router failed again.  Erik followed the procedure in T2300212 to remove the router and use the backup router.

The backup router had been tested on the test stand.  The config needed two changes to the route table to make things work.  This was largely an artifact of it being built and tested on the test stand.  There was a old test stand ip address in the route table and one of the internal routes needed a larger network mask.

The new router appears to be working and we are able to allow remote access to CDS and to reach the outside world.

Nyath also checked the GC switch that the CDS router connects to to make sure that there were no problems with MAC address locks not allowing the change in routers.
