High-level task to document the migration on our core routers in eqiad of the links running from asw2-d-eqiad to our core routers. Specifically these links:
| ASW Side (not moving) | Currently connected to | Needs to move to |
|---|---|---|
| asw2-d2-eqiad et-2/0/49 | cr1-eqiad et-1/1/3 | ssw1-d1-eqiad ethernet-1/29 |
| asw2-d7-eqiad et-7/0/53 | cr2-eqiad et-1/1/3 | ssw1-d8-eqiad ethernet-1/29 |
Once migrated traffic will flow, instead of directly from core routers to the asw2-d-eqiad virtual-chassis, via our new Nokia Spine switches (already connected to the core routers on et-1/0/5 respectively) and then to the old Junipers. This will extend the vlans for row D to the Nokia switches which will allow us to move forward and start migrating server connections to them.
Vlans
The following vlans/sub-interfaces are affected:
