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 is not 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 cannot be enabled.
• The default route must exist on each SteelHead in your network.
Mapping Data Collection Setting
Complete the configuration as described in this table.
Control | Description |
Collect Mappings From | Select one of these options from the drop‑down list: • None - Do not collect mappings. • Destination Only - Collects destination MAC data. Use this option in connection-forwarding deployments. This is the default setting. • Destination and Source - Collect mappings from destination and source MAC data. Use this option in connection-forwarding deployments. • All - Collect mappings for destination, source, and inner MAC data. Also collect data for connections that are un-NATted (that is, connections that are not translated using NAT). |
