ES4710BD 10 Slots L2/L3/L4 Chassis Switch
17.1.2.2Layer 3 Interface Configuration Commands
17.1.2.2.1interface vlan
Command: interface vlan <vlan-id> no interface vlan <vlan-id>
Function: Creates a VLAN interface (a Layer 3 interface); the “no interface vlan
Parameters:
Default: No Layer 3 interface is configured upon switch shipment.
Command mode: Global Mode
Usage Guide: When crating a VLAN interface (Layer 3 interface), VLANs should be configured first, for details, see the VLAN chapters. When VLAN interface (Layer 3 interface) is created with this command, the VLAN interface (Layer 3 interface) configuration mode will be entered. After the creation of the VLAN interface (Layer 3 interface), interface vlan command can still be used to enter Layer 3 interface mode.
Example: Creating a VLAN interface (layer 3 interface). Switch (Config)#interface vlan 1
17.2IP Forwarding
17.2.1 Introduction to IP Forwarding
Gateway devices can forward IP packets from one subnet to another; such forwarding uses routes to find a path. IP forwarding of ES4710BD is done with the participation of hardware and so wire speed forwarding can be achieved. In addition, flexible management is provided to adjust and monitor forwarding. ES4710BD supports aggregation algorithm enabling/disabling optimization to adjust segment route generation in the switch chip and view statistics for IP forwarding and hardware forwarding chip status.
17.2.2 IP Route Aggregation Configuration
17.2.2.1IP Route Aggregation Configuration Task
1. Set whether IP route aggregation algorithm with/without optimization should be used.
Command
ip fib optimize
Explanation
Enables the switch to use optimized IP route
