We will performing network maintenance tonight and will need to take an OSPF neighbor down. I've read on some Google searches on performing a graceful shutdown and wanted to see someone's take on it.
I need to shutdown the OSPF on our 6509 and then re-enable it with a port channel configuration. Can i use the "max-metric router-lsa" command against router ospf 100 to force this device to start shifting traffic to different routers/OSPF neighbors?
The 6509 is connected to 2 ASR's (Level 3 & Sprint) and another 7609 (which is also connected to L3 & Sprint). I need to shutdown interface gi 4/45 (facing the ASR L3) in order to upgrade to a 2gb port-channel and restore OSPF. Is there a better method of performing a graceful shutdown?

Thanks in advance!
