Baseline configuration
- Cloudsw vlans (L2) - 1102, 1103, 1104, 1120
- iBGP and OSPF between cloudsw
- eBGP between core routers and cloudsw (185.15.56.0/24 and 172.16.0.0/21, receive 0/0)
- Static route for 185.15.56.0/25 and 172.16.0.0/21 on cloudsw
- Firewall filters - lo, cloud-in4 (on core routers)
- Test connectivity
cloud-instances-transport migration (downtime required [!])
- Ensure cr1 is VRRP master for all vlans, including 1120
- Move cr2:ae2.1120 to cloudsw1-d5:irb.1120
- Test cr1:ae2.1120 to cloudsw1-d5:irb.1120 connectivity (and VRRP sync)
- Ensure static routes are active and aggregates propagated on cloudsw1-d5
- [!] Move vlan 1120 VRRP master to cloudsw1-d5:irb.1120
- [!] Remove static routes for 185.15.56.0/25 and 172.16.0.0/21 on core routers
- Test connectivity
- Move cr1:ae2.1120 to cloudsw1-c8:irb.1120
- Cleanup (remove passive OSPF, trunked vlans, update Netbox)
Renumber cloud-instances-transport (downtime required [!]) (similar to T207663)
- Allocate IPs
- Configure 185.15.56.240/29 IPs on all devices
- [!] Reconfigure cloudnet with new gateway IP (to be confirmed)
- [!] Update static routes on cloudsw to point to new VIP
- Cleanup 208.80.155.88/29 IPs and advertisement (+Netbox)
