FS#14118 — FS#20467 — gra-3ab-a9

Attached to Project— Network
Maintenance
Whole Network
In progress
0%
Certain links on the gra-3ab-a9 router are used at 100%
capacity. The network team is ready to carry out
migration to new 40G and 100G routers, but these
new routers are not well managed by the backend.
Given the urgency, we will begin the migration anyway
because the quality is not in question. Then the code will be
ended for configurations of IP FO etc.

We will move the first networks to N9. There is no outage expected, but the robots will not be on during this operation.

A routing session is not properly functioning on one of the routers. We will restart it.


Comment by OVH - Wednesday, 21 September 2016, 17:58PM

The configuration is ready to migrate the following 7 vlans, that action will be taken in the next few minutes.


Comment by OVH - Wednesday, 21 September 2016, 17:58PM

The first bang is migrated, the IPs are gradually returning


Comment by OVH - Wednesday, 21 September 2016, 17:59PM

The 3rd VLAN has been migrated.


Comment by OVH - Wednesday, 21 September 2016, 19:04PM

In order to add a hardware management feature, we will patch the routers one by one.


Comment by OVH - Thursday, 22 September 2016, 17:47PM

Migration is not going as expected. The new routers
are not working as planned and the CPU has been quckly
saturated with 4 vlan (1000 servers).
Normally, the router must endure 3x plus minimum without any problems.
We will change the configuration in order to avoid the CPU saturation.
If this situation persists, we will use another router tomorrow.
We will determine if there is a problem with the
hardware or the software (same hardware and 2 manufacturers).

We have found a solution to be able to support up to 16 vlans on every couple of new routers. We will resume migration of VLANs one by one with no outage expected (just a cut of 2-3 seconds by the time of the re-arp machines).


Comment by OVH - Thursday, 22 September 2016, 17:51PM

Migration of 5th VLAN starting...


Comment by OVH - Thursday, 22 September 2016, 17:53PM

The 6th VLAN has been migrated. 4 servers do not correctly re-arp and have not migrated.


Comment by OVH - Thursday, 22 September 2016, 17:54PM

The last VLANs have been migrated.


Comment by OVH - Thursday, 22 September 2016, 17:54PM

We will migrate new 4 vlans on new router couples.


Comment by OVH - Thursday, 22 September 2016, 17:56PM

The IPFO have taken longer to converge than the main IP.


Comment by OVH - Thursday, 22 September 2016, 17:56PM

We are proceeding to the final part of the migration of 4 vlans.


Comment by OVH - Thursday, 22 September 2016, 17:59PM

Until now the following ranges have been moved:
151.80.33.0/24
151.80.34.0/24
151.80.35.0/24
151.80.36.0/24
149.202.74.0/24
149.202.75.0/24
149.202.76.0/24
149.202.77.0/24
149.202.82.0/24
149.202.83.0/24
149.202.84.0/24
149.202.85.0/24

we will move 4 new VLANs to the new router couple. For now 50G of traffic has been moved.


Comment by OVH - Thursday, 22 September 2016, 18:00PM

The migration of the last vlans is completed. Traffic should gradually return to each equipment.
