In anticipation of the introduction of vss-1b/2b/3b new routers which will help us to get a redundant routing of \"first hop\", we pass the gateways of each vlan on HSRP.
No expected impact on traffic.
Update(s):
Date: 2011-04-21 15:34:20 UTC We activate the routing on vss-2b/3b/4b.
Date: 2011-04-21 15:33:43 UTC Following activation of routing on vss-1b, a part of the internal traffic was impacted from/to networks 94.23.0 57. Randomly, some ips were no longer reachable from other networks in intra ovh.
Date: 2011-04-21 15:31:57 UTC We freeze updates of IPs FO on vss-1-6k.
Date: 2011-04-21 15:31:13 UTC The vss-1b/2b/3b are connected on all vlans routed by vss-1/2/3/4. We configure routing this morning to enable them to resume the traffic in case of interruption of the primary routing. To do this, we need to temporarily freeze the configuration of IP fail-over successively on vss-1/2/3 (between 30min and 1h by router)
Date: 2011-04-19 13:26:58 UTC We move to vss-4-6k.
Date: 2011-04-19 11:12:25 UTC Now we intervene on vss-3-6k.
Date: 2011-04-19 10:17:51 UTC We intervene on the vss-2-6k.
Date: 2011-04-14 12:06:27 UTC The vlans routed by vss-1 were switched.
