■

A non-MPLS card can be used for access to the private network side, and an 
MPLS card must be used for access to the public network side;

■

You cannot perform other configurations on the destination port in intermixed 
networking, that is to say, the port view is unavailable. In addition, the 
destination port in intermixing networking cannot be deleted from the VLAN in 
the normal way, and the destination port is an inloop port;

■

The configured connection status of the source port in intermixing networking 
is protected. For example, the port type cannot be changed form Trunk to 
Access or from Access to Trunk, and the source port cannot be deleted from 
VLAN in the normal way;

■

The configuration of the service ports in intermixing networking cannot be 
changed, and the service ports can be reconfigured only after the intermixing 
configuration is removed;

■

In a VLAN, multiple ports of the non-MPLS card can be redirected to one port 
of the MPLS card. The destination port of the MPLS card is Looped back 
automatically (becomes a Loopback port) after it is configured for redirection, 
and you cannot perform other configurations on the port. Therefore, make 
sure that the destination port is not in manual Shutdown state before 
configuring redirection. Only one Loopback port is allowed in the redirected 
VLAN that the destination port belongs to, but other MPLS card ports are 
allowed to join in;

■

On the Trunk port of a non-MPLS card, you can redirect the MPLS VPNs of 
multiple VLANs to one destination port to meet the need when the access CE is 
a Layer 2 switch;

■

In non-intermixing networking, VLL application requires that VLANs with only 
one port be used at the private network side; In intermixing networking, VLL 
supports only VLANs with two ports: one is the source port (port of the 
non-MPLS card) and the other is the destination port (port of the MPLS card);

■

When the source port (Trunk port) in intermixing networking belongs to 
multiple VLANs, VPN binding must be implemented on the VLAN interfaces 
after the redirection configuration;

■

If VRRP is configured on the VLAN interface to which the redirected source port 
of the MPLS VPN belongs, the plugging/unplugging of the MPLS card will 
cause VRRP group state switching on the VLAN interface.

■

Source port aggregation and destination port aggregation are not supported;

■

Nested VPN is not supported;

■

Super VLAN is not supported;

■

It is not allowed to change the attributes of the redirected source port;
