Enabling simplified routing
You enable simplified routing in the Simplified Routing page.
These options are available to configure simplified routing:
Collect Mappings From specifies one of these options from the drop-down list:
• None—Does not collect mappings.
• Destination Only—Collects mappings from destination IP, destination MAC, and VLAN tag (when deployed on 802.1q trunk). We recommend that you use this setting for most deployments with multiple in-paths or connection forwarding SteelHeads. SteelHeads do not usually learn incorrect mappings unless the network devices themselves are routing incorrectly. This is the default setting.
• Destination and Source—Collects mappings from destination and source IP, destination and source MAC, and VLAN tag (when deployed on 802.1q trunk).
• All—Collects mappings for destination, source, and inner MAC data. Also collect data for connections that are un-NATted (that is, connections that aren’t translated using NAT).
Enable simplified routing for GRE-tunneled pass-through packets enables simplified routing for GRE tunnel pass-through traffic. Enabling this setting avoids packet ricochet between the server-side SteelHead and the server-side SteelHead gateway for pass-through packets from GRE tunnels. This setting applies to TCP and UDP packets.
