    <description>&lt;P&gt;I have a environment which has two data centers,&amp;nbsp; &amp;nbsp;in an active passive configuration..&amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp;Virtual Servers can be migrated from one site to the other.&amp;nbsp; &amp;nbsp; &amp;nbsp;There is a requirement that the IP address's for servers dont' change if they are migrated.&amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp;&lt;BR /&gt;&lt;BR /&gt;At a network layer, this is a little problematic, as the vlan interfaces on the FW instances stay turn on, which means that the routing tables for the two datacenters&amp;nbsp; both have routes for the local vlans. ( even though only one is actually 'alive'.&amp;nbsp; &amp;nbsp;&lt;BR /&gt;&lt;BR /&gt;These firewall instances are set up across a cluster.&amp;nbsp; &amp;nbsp; What i'd like to do is set the state of the interfaces to off.&amp;nbsp;&lt;BR /&gt;&lt;BR /&gt;&lt;FONT face="terminal,monaco"&gt;set interface&amp;nbsp; eth9.99 state down&lt;BR /&gt;&lt;BR /&gt;&lt;/FONT&gt;In theory this should remove the routes from the firewall, and it will stop redistributing them into OSPF.&amp;nbsp; &amp;nbsp;&amp;nbsp;&lt;BR /&gt;&lt;BR /&gt;Is there any issues with doing this, particually in a cluster?&amp;nbsp; &amp;nbsp; This can easily be automated as part of the DR 'failover'.&amp;nbsp;&lt;BR /&gt;Right now there is some very complex Nat going on, and i'd like to clean it up.&amp;nbsp; ( there is not ever a case where both locations need to be 'alive' at the same time.&lt;BR /&gt;&lt;BR /&gt;&lt;/P&gt;&lt;P&gt;TIA&amp;gt;&lt;/P&gt;</description>
