network address reconfig - what becomes my def gw?

looking to reconfig existing address space to NEW ip's.....

-move from single c6500 to dual c6500s w/ single sup720 in each

-remove vlan 1 and move to mgmt vlan 300

assuming vlan 1 (192.168.1.1) is being removed and mgmt vlan 300 (172.16.1.1-172.16.1.50) is config'd...what ip address becomes the default gateway for the entire network? (note: C6500s are doing ALL L3 for network...there is no router)

sample config: (am i thinking correctly on this one?)

core-1 w/ single sup 720

interface vlan 300

172.16.1.2 255.255.0.0

standby 1 ip 172.16.1.1

standby 1 priority 150

standby 1 preempt

core-2 w/ single sup720

interface vlan 300

172.16.1.3 255.255.0.0

standby 1 ip 172.16.1.1

standby 1 priority 100

standby 1 preempt

does the defaul gateway become 172.16.1.1? (which is the same address range of mgmt vlan?)

Hi

If you are changing the mgmt ip of your switch network , then the HSRP ip configured above would be the default for others.And you are correct.

Yes, you are right. 172.16.1.1 will become default gateway for devices which are member of management VLAN.

rate if it helps ...
