Configuring forwarding parameters
The following configurable parameters control the forwarding behavior of the device:
• Time-To-Live (TTL) threshold
• Forwarding of directed broadcasts
• Forwarding of source-routed packets
• Ones-based and zero-based broadcasts
All these parameters are global and thus affect all IP interfaces configured on the device.
To configure these parameters, use the procedures in the following sections.
BigIron RX# show ip static route
