between VLANs
4.2.1 Establishing the configuration task
Applicable environment
To implement Layer 3 interconnection between VLANs, routers or Layer 3 switches must be
used to connect VLANs. This section describes how to interconnect VLANs through routers.
To achieve communication between VLANs, create subinterfaces on the Ethernet interfaces
that connect routers with switches, and then encapsulate the subinterfaces with 8021.Q.
Preconfiguration tasks
Before you configure VLAN encapsulation, you need to create an Ethernet subinterface and
configure its attributes.
Data preparation
To encapsulate packets on the subinterfaces with 802.1Q, you need the following data.
No.
Data
1
Interface number of the Ethernet interface and subinterface
2
IP address and mask of the subinterface
3
ID range of the VLAN to which the interface belongs
