Is Vlan 2122 cloud-support1-b-codfw required?
Closed, ResolvedPublic


This Vlan exists in codfw and has a VRRP gateway configured between the two CRs there:

It's got no hosts connected to it, however:

The equivalent in eqiad has labstore, dbproxy, cloudmetrics hosts on it, as well as LVS load-balancers which front some services they host.

It seems to be that when we have a working model for the CloudLB we can revisit the eqiad Vlan and possibly migrate away? And if that is indeed the longer-term plan then we should remove the unused cloud-support1-b-codfw vlan in codfw, and get things working in the CloudLB POC instead?

Event Timeline

cmooney created this task.

I guess this was set up to mirror the eqiad setting. Since this VLAN as no room in the new network model (described wikitech)

Agreed, I think it should be good to drop from the codfw setup any time.

Thanks for the feedback @aborrero. I'll plan on getting it decommissioned.
