Get webhook notifications whenever Network & Infrastructure creates an incident, updates an incident, resolves an incident or changes a component status.
We will simplify the configurations on the
network by setting 3 routers reflectors
that will take and centralize all the BGP
announcements of all backbone routers,
recalculate the best route and then redistribute
the BGP table on all routers.
We should gain in BGP performance and in reliability
on the optic fibre cuts.
Update(s):
Date: 2010-09-25 16:40:53 UTC We have always the same error messages on the 3 route collectors :
Date: 2010-09-21 23:43:19 UTC We are cleaning all useless BGP sessions.
Date: 2010-09-19 19:49:28 UTC Work on the reflector IPv4 was completed.
We will start work on IPv6.

We will remove the same routes from BGP.
Date: 2010-09-09 08:09:48 UTC We will insert the OSPF routes in the network.
Date: 2010-09-07 09:27:25 UTC Right now , all the backbone runs in the
\"route reflector\" configuration.
Still to be done :
-The BGP rewriting to OPSF at the level of certain interfaces.
- put IPv6 on the \"route reflector\" configuration.
Date: 2010-09-07 09:24:17 UTC We have finished the working for the changes
to the route refelectors of ip failover p19 ,roubaix1
and dc1/gsw at the level of the housing.
Date: 2010-09-07 07:36:19 UTC We are going to cut the the m1/m2 router announcements from roubaix1 to rbx-1.
The three route refelctors will retake the announcements.
Date: 2010-09-07 07:28:16 UTC We continue with the th1.
Date: 2010-09-07 07:27:37 UTC All m1/m2 are in the 3 routes reflectors.
Date: 2010-09-07 07:26:48 UTC We are setting the third rf.
Date: 2010-09-07 07:26:02 UTC We are going to change the rf-1 on the new hardware.

Now we can continue the development of the route reflector
from tomorrow on the more complicated routers in terms of

Date: 2010-08-23 19:22:17 UTC VIX works on 193.203.0.0/24 which is a private network.
For an unknow reason VIX announces this network on Internet.
The trafic was redirected. We have filtered the announcements
in order to avoid having 193.203.0.0/24 in the BGP
Date: 2010-08-23 19:16:30 UTC We will put the configuration on vie-1-6k
Date: 2010-08-23 18:03:54 UTC We took a good old 6509 in BXL and we succeeded to mount
all the BGP sessions of all the routers.
It's due to the limit of the available memory : 1 Gb

That's not what the cisco.com site says (2Gb of
RAM on the XL card and 4Gb on the sup ) but well ... Marketing.
So the conclusion is simple : Nexus 7000 is not usable at OVH.
Date: 2010-08-23 17:44:56 UTC The Nexus 7000 does not allows to do it.
It has only 256 Mb of RAM in one context and cannot take several
BGP full route sessions to recalculate them. It crashes.
Date: 2010-08-23 17:37:04 UTC We should receive the 3 ASR 1000 by the end of August.
In the meanntime, we test this functionnality on the nexus 7000.
