What switch model are you trying to configure this on?  I’m not familiar with a way to shutdown a VLAN without deleting it.

62xx(config-if-vlan200)#?

bandwidth                Configure Bandwidth.

bridge                   Configure bridge table.

encapsulation            Configure interface link layer encapsulation type.

exit                     To exit from the mode.

ip                       Configure IP parameters.

ipv6                     Configure IPv6 parameters.

mac                      Configure MAC Access List group parameters.

name                     Configure an optional VLAN Name.

routing                  Enables routing for an interface, Use no form to disable.

Have you looked into setting up VRRP for a disaster recovery plan?

VRRP

The Virtual Router Redundancy (VRRP) protocol is designed to handle default router failures by

providing a scheme to dynamically elect a backup router. The driving force was to minimize “black hole”

periods due to the failure of the default gateway router during which all traffic directed towards it is lost

until the failure is detected. Though static configuration of default routes is popular, such an approach is

susceptible to a single point of failure when the default router fails. VRRP advocates the concept of a

“virtual router” associated with one or more IP Addresses that serve as default gateways. In the event that

the VRRP Router controlling these IP Addresses (formally known as the Master) fails, the group of IP

Addresses and the default forwarding role is taken over by a Backup VRRP Router.

The VRRP Router Configuration feature enables interface and route tracking. Use VRRP tracking to

ensure the best VRRP router is Master for the group.

VRRP interface tracking monitors a specific interface IP state within the router. Depending on the state

of the tracked interface, the feature can alter the VRRP priority level of a virtual router for a VRRP group.

An exception to the priority level change is that if the VRRP group is the IP address owner, its priority is

fixed at 255 and cannot be reduced through the tracking process.

VRRP route tracking monitors the reachability of an IP route. A tracked route is considered up when a

routing table entry exists for the route and the route is accessible. To configure route tracking, make

VRRP a best route client of RTO. When a tracked route is added or deleted, change the priority.

We are using Dell PowerConnect 6248P switches at both locations.  The core switches host all of the interVLAN routing.  We use the default VLAN to route across the WAN, which is done with  and Cisco 28xx routers.
