Hi,
-=Routed Mode=-
-VLANs can be shared between contexts.
-Servers behind ACE use ACE as a gateway. That means that you have to change the subnet/gateway on your server to point directly to ACE and create a new IP subnet on the server/ACE. (note that the server would not have to be L2 adjacent necessarily, but you will need to create 2 subnets on ACE and the server should be behind one of them in a manner where all traffic to/from the server only traverses that path. If the routing behind the server has a path around the ACE, you will have to use source NAT or PBR to make sure loadbalanced flows are symetric.)
-Non-loadbalanced flows can be NATted
-Access to the servers chagnes because of the new subnet. You can configure static NAT on ace to reach the servers via the old IP's if needed - or update the routing within the network to reach the servers through ACE.
ONE ARM mode is still routed mode but you have vip and server's are in the same vlan.
-=Bridged Mode=-
-VLANs that are bridged can not be shared between contexts.
-Servers behind ACE use the same gateway as previously. The only change to the existing topology is L2 VLANs. You will put your servers on a new L2 vlan behind ACE. ACE will bridge the new VLAN with the existing VLAN to allow traffic flow.
-Non-loadbalanced flows can not be NATted. (this is probably the only real limitiation between bridged and routed.)
-Clients can access the servers directly, the same as before the change, no special routing/natting will need to be done.
