This is regarding HW replacement/migration effort with no-disrupting in network services - from Cisco IOS to NXOS:
OSPF Area 4: A new pair of N9K just directly added to the backbone (Area 0)
OSPF Area 4: An existing pair of Catalyst IOS 6500s currently is handling the traffic for the existing endpoints connected to Area# 4
so:
OSPF Area 0: both N9K as well as 6500s are connected directly to backbone til Nexus N9K fully take over the passing traffic.
I'm seeking feedback/input as to avoid any routing issues - to manually adjust OSPF metrics on N9K switches to be tweaked to make sure incoming/outgoing traffic go thru WS-C6500's as before.
I'm not too familiar with NXOS OSPF compatible CLI yet.
Please help me out
Thanks
