Typical Networking
Example
MPLS S
UPPORT
The source port joins in the corresponding VLAN automatically after the
■
configuration of intermixing redirection, and the source port leaves the
corresponding VLAN automatically after the intermixing redirection is deleted.
When using the VPLS intermixing redirection command, you have to enable
■
join-vlan explicitly.
When using the VLL VPN intermixing redirection command, you must not
■
enable the QinQ function on the source port and destination port.
Network requirements
CE1 and CE3 constitute VPN A, and CE2 and CE4 constitute VPN B. In PE1, a
■
port of an interface card is shared, and in PE2, a Layer 2 switch is shared to
connect with the host directly.
The PE devices (PE1 and PE2) are Switch 8800 Family series switches, and the
■
PE devices need to support the MPLS function. CE1 and CE2 are common
mid-range and low-end routers. CE3 and CE4 are Layer 2 switches connected
with users directly.
The configurations of the interface cards of the two PE devices are the same.
■
On slot3 is a non-MPLS card with 100M Ethernet ports, and on Slot 2 is an
MPLS card with Gigabit Ethernet ports.

Configuration procedure
1 Configure CE1
# Configure CE1 and CE2 as EBGP neighbors and import direct routes and static
routes So that the VPN user routes of CE1 are imported into BGP routes and then
advertised to PE1.
