Right way of moving cable

Sujanya — Fri, 05 Apr 2024 16:26:23 GMT

Please find the exsisting set-up:

Juniper switch---ospf--->Palo-Alto firewall------------tunnel-----> External 3rd party Cisco Router

We are planning to change the Juniper switch to Cisco switch and make the configuration as below:

Cisco switch---ospf--->Palo-Alto firewall------------tunnel-----> External 3rd party Cisco Router

Before we planning the above changes , is there any necessary to bring the tunnels down and then to move the cable , is it a good way.....? or since we are not touching any configurations between firewall and the 3rd party cisco router is there any actual need to bring the tunnel down?

Hi @Sujanya ,

You can keep the tunnel up. I would recommend scheduling a maintenance window and informing the third-party vendor that certain networks that they might be accessing through the tunnel will be down momentarily from switching out your core.

Hi @JayGolf ,

Thank you for the response. Will Swaping the core will not make the tunnel to go down or it will just Break the connectivity with the server as ospf will break and re-established with cisco switch.
