Operation Manual – MPLS Hybrid Insertion
H3C S9500 Series Routing Switches
The traffic-redirect command is used to enable ACL flow classification and redirect
the packets (only applicable to the rules whose action is permit in the ACL). There are
two kinds of redirection commands:
Redirect packets to a port: You can redirect packets received by the source port of
the non-MPLS card to the specified destination port of the MPLS card.
Redirect packets to a service processor card: You can redirect packets received
by the source port of the non-MPLS card or MPLS card to the VPLS card.
There are two kinds of redirection services:
VPLS-related redirection services: The key word join-vlan must be specified, and
the system will add the current port into destination-vlan after the redirection
enabled; when redirection is disabled, the system will log the current port out of the
VLAN if what is deleted is a join-vlan enabled redirection in the VLAN.
MPLS-independent redirection services: Such redirection services include NAT,
URPT, reflexive ACL, BT traffic control and so on. join-vlan cannot be enabled in
such a service. The port will not be added into VLAN when redirection is
configured, and the port will not be removed from the VLAN when redirection is
deleted.
Note:
The source port joins in the corresponding VLAN automatically after the
configuration of MPLS hybrid insertion redirection, and the source port leaves the
corresponding VLAN automatically after the MPLS hybrid insertion redirection is
deleted.
When using the VPLS hybrid insertion redirection command, you have to enable
join-vlan explicitly.
When using the VLL VPN hybrid insertion redirection command, you must not
enable the QinQ function on the source port and destination port.
1.3.7 Typical Networking Example
I. Network requirements
CE1 and CE3 constitute VPN A, and CE2 and CE4 constitute VPN B. In PE1, a
port of an interface card with suffix CA is shared, and in PE2, a Layer 2 switch is
shared to connect with the host directly.
The PE devices (PE1 and PE2) are S9500 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.
