Enabling
Simplified
Routing
You can enable simplified routing in the Advanced Networking - Simplified Routing
page.
Simplified routing collects the IP address for the next hop Media Access Control
(MAC) address from each packet it receives to use in addressing traffic. Enabling
simplified routing eliminates the need to add static routes when the HP EFS WAN
Accelerator is in a different subnet from the client and server.
Without simplified routing if an HP EFS WAN Accelerator is installed in a different
subnet from the client or server you must define one router as the default gateway and
static routes for the other routers so that traffic is not redirected back through the HP
EFS WAN Accelerator. However, in some cases, even with the static routes defined,
the Access Control List (ACL) on the default gateway may still drop traffic that should
have gone through the other router.
Simplified routing has the following constraints:
‹ Broadcast support in Proxy File Service (PFS) configurations cannot be enabled.
‹ WCCP cannot be enabled.
‹ Connection forwarding cannot be enabled if you collect mappings for source
MAC data (that is, the options all or dest-source).
‹ The default route must exist on each HP EFS WAN Accelerator in your network.
‹ Simplified routing requires a client-side and server-side HP EFS WAN
Accelerator.
