I came upon a site that has three nexus switches; two within a vPC pair, and the other only connected to one in the pair. They said it was a limitation of their fiber availibility. Anyway, I notice that their MGMT0 interfaces are within the same network as their vlan used to route traffic.
Such as;
Each switch is basically setup in this fashion only different IPs for each interface, but all within the same subnet.
int MGMT 0
ip address 192.168.2.25 255.255.255.0
inter vlan 4
ip address 192.168.2.26 255.255.255.0
The "show ip route" shows everything being routed over the 192.168.2.26 back to the layer 3 core. Would this type of setup cause any issues? I don't see any broadcast storm indications on the "show interface" commands. No links flapping. It just seems strange. Their NTP, and SNMP traffic goes over the MGMT0 interface.
