About simplified routing features
Settings for enabling simplified routing are under Networking > Network Integration: Simplified Routing.
Simplified routing collects the IP address for the next hop MAC address from each packet it receives to address traffic. With simplified routing, you can use either the WAN or LAN side device as a default gateway. The SteelHead learns the right gateway to use by watching where the switch or router sends the traffic, and associating the next-hop Ethernet addresses with IP addresses. Enabling simplified routing eliminates the need to add static routes when the SteelHead is in a different subnet from the client and the server.
Without simplified routing, if a SteelHead 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 isn’t redirected back through the SteelHead. In some cases, even with the static routes defined, the ACL on the default gateway can still drop traffic that should have gone through the other router. Enabling simplified routing eliminates this issue.
Simplified routing has these constraints:
• WCCP can’t be enabled.
• The default route must exist on each SteelHead in your network.
For detailed configuration information, see the SteelHead Deployment Guide.
The Cloud Accelerator isn’t deployed in-path, but in its unique out-of-path method, using one interface. Simplified routing doesn’t apply.
The simplified routing feature in RiOS 8.5 and later is compatible with IPv6.
