Because the destination port in intermixing configuration is to be looped back and
therefore is locked automatically, you cannot enter the port view. Therefore, you
cannot perform other configurations on the destination port.

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
