Huawei quidway s7700 - Configuring VLANIF Interfaces for Inter-VLAN Communication

Pre-configuration Tasks
Before configuring inter-VLAN communication, complete the following task:
l Creating VLANs
Data Preparation
To configure inter-VLAN communication, you need the following data.
No. Data
1 Number of each Ethernet sub-interface, IP address and mask of the sub-interface,
and VLAN ID associated with the sub-interface
2 VLAN ID, VLANIF interface number, IP address and mask of the VLANIF
interface
3 (Optional) Port type, VLAN ID before mapping, VLAN ID after mapping, outer
VLAN ID to be added, source port number, and destination port number
3.5.2 Configuring VLANIF Interfaces for Inter-VLAN
Communication
Configuring VLANIF interfaces for inter-VLAN communication saves expenditure and helps
implement fast forwarding.
Context
VLAIF interfaces are Layer 3 logical interfaces. After being assigned IP addresses, VLANIF
interfaces are able to communicate at the network layer.
By using VLANIF interfaces to implement inter-VLAN communication, you need to configure
a VLANIF interface for each VLAN and assign an IP address to each VLANIF interface. The
communication process by using VLANIF interfaces is similar to that by using sub-interfaces.
