Operation Manual – MPLS Hybrid Insertion
H3C S9500 Series Routing Switches
Use the port of the non-MPLS card for the access to the service private network
side of the MPLS VPN ;
Redirect the port of the non-MPLS card through QACL, to redirect the received
packets to the specified MPLS card for processing;
The port of MPLS card is set as Loopback port automatically and the port type is
Trunk;
The access port of the non-MPLS card and the Loopback port of the MPLS card
belong to the same VLAN.
The port on the MPLS card can also be used for the access to the service private
network side of the MPLS VPN. In this case, you do not need to configure MPLS hybrid
insertion, and you must use the port of the MPLS card for the connection with the MPLS
public network side.
Note:
Because the destination port in MPLS hybrid insertion 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.
1.2 Restrictions on MPLS Hybrid Insertion Networking
1.2.1 Rules of MPLS Hybrid Insertion Configuration
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 MPLS hybrid
insertion networking, that is to say, the port view is unavailable. In addition, the
destination port in MPLS hybrid insertion 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 MPLS hybrid insertion
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 MPLS hybrid insertion networking cannot
be changed, and the service ports can be reconfigured only after the MPLS hybrid
insertion 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.
