Example for Configuring MAC Address Limiting in a VSI

Example for Configuring MAC Address Limiting in a VSI

Networking Requirements

In Figure 2-17, the enterprise establishes a backbone network. MAC address limiting needs to be configured in VSIs on the PEs for access control of CEs, ensuring the backbone network security.

Figure 2-17  Networking of MAC address limiting in a VSI

Configuration Roadmap

The configuration roadmap is as follows:

  1. Configure a routing protocol on the backbone network to implement the interworking.

  2. Set up remote LDP sessions between PEs.

  3. Set up a tunnel between PEs to transmit user data.

  4. Enable MPLS L2VPN on PEs.

  5. Configure a VSI and specify LDP as the signaling protocol on PEs.

  6. Configure MAC address limiting in the VSI on PEs to control access of CEs.

Procedure

  1. Create VLANs on the CE, PE, and P devices, add interfaces to respective VLANs, and assign IP addresses to VLAN interfaces.

    # Configure CE1.

[CE2] interface gigabitethernet 1/0/0
[CE2-GigabitEthernet1/0/0] port link-type trunk
[CE2-GigabitEthernet1/0/0] port trunk allow-pass vlan 40
[CE2-GigabitEthernet1/0/0] quit

    # Configure PE1.

[PE1] interface gigabitethernet 2/0/0
[PE1-GigabitEthernet2/0/0] port link-type trunk
[PE1-GigabitEthernet2/0/0] port trunk allow-pass vlan 20
[PE1-GigabitEthernet2/0/0] quit

    # Configure the P.

[P-GigabitEthernet1/0/0] port link-type trunk
[P-GigabitEthernet1/0/0] port trunk allow-pass vlan 20
[P-GigabitEthernet1/0/0] quit
[P] interface gigabitethernet 2/0/0
[P-GigabitEthernet2/0/0] port link-type trunk
[P-GigabitEthernet2/0/0] port trunk allow-pass vlan 30
[P-GigabitEthernet2/0/0] quit

    # Configure PE2.

    <HUAWEI> system-view
[HUAWEI] sysname PE2
[PE2] vlan batch 30 40
[PE2] interface vlanif 30
[PE2-Vlanif30] ip address 5.5.5.2 255.255.255.0

[PE2-GigabitEthernet2/0/0] port link-type trunk
[PE2-GigabitEthernet2/0/0] port trunk allow-pass vlan 40
[PE2-GigabitEthernet2/0/0] quit

  2. Configure an IGP. OSPF is used in this example.

    Configure OSPF to advertise the loopback interface addresses (LSR IDs) with 32-bit mask length of PE1, P, and PE2.

    # Configure PE1.

    [PE1] router id 1.1.1.1
[PE1] interface loopback 1
[PE1-LoopBack1] ip address 1.1.1.1 32
[PE1-LoopBack1] quit
[PE1] ospf 1
[PE1-ospf-1] area 0
[PE1-ospf-1-area-0.0.0.0] network 1.1.1.1 0.0.0.0
[PE1-ospf-1-area-0.0.0.0] network 4.4.4.4 0.0.0.255
[PE1-ospf-1-area-0.0.0.0] quit
[PE1-ospf-1] quit

    # Configure the P.

    [P] router id 2.2.2.2
[P] interface loopback 1
[P-LoopBack1] ip address 2.2.2.2 32
[P-LoopBack1] quit
[P] ospf 1
[P-ospf-1] area 0
[P-ospf-1-area-0.0.0.0] network 2.2.2.2 0.0.0.0
[P-ospf-1-area-0.0.0.0] network 4.4.4.2 0.0.0.255
[P-ospf-1-area-0.0.0.0] network 5.5.5.5 0.0.0.255
[P-ospf-1-area-0.0.0.0] quit
[P-ospf-1] quit

    # Configure PE2.

    [PE2] router id 3.3.3.3
[PE2] interface loopback 1
[PE2-LoopBack1] ip address 3.3.3.3 32
[PE2-LoopBack1] quit
[PE2] ospf 1
[PE2-ospf-1] area 0
[PE2-ospf-1-area-0.0.0.0] network 3.3.3.3 0.0.0.0
[PE2-ospf-1-area-0.0.0.0] network 5.5.5.2 0.0.0.255
[PE2-ospf-1-area-0.0.0.0] quit
[PE2-ospf-1] quit

    After the configuration is complete, run the display ip routing-table command on PE1, P, and PE2. The command output shows that PE1, P, and PE2 have learned routes from each other. The display on PE1 is used as an example.

    [PE1] display ip routing-table

      127.0.0.1/32  Direct  0    0           D   127.0.0.1       InLoopBack0

  3. Configure basic MPLS functions and LDP.

    # Configure PE1.

    [PE1] mpls lsr-id 1.1.1.1
[PE1] mpls
[PE1-mpls] quit
[PE1] mpls ldp
[PE1-mpls-ldp] quit
[PE1] interface vlanif 20
[PE1-Vlanif20] mpls
[PE1-Vlanif20] mpls ldp
[PE1-Vlanif20] quit

    # Configure the P.

    [P] mpls lsr-id 2.2.2.2
[P] mpls
[P-mpls] quit
[P] mpls ldp
[P-mpls-ldp] quit
[P] interface vlanif 20
[P-Vlanif20] mpls
[P-Vlanif20] mpls ldp
[P-Vlanif20] quit
[P] interface vlanif 30
[P-Vlanif30] mpls
[P-Vlanif30] mpls ldp
[P-Vlanif30] quit

    # Configure PE2.

    [PE2] mpls lsr-id 3.3.3.3
[PE2] mpls
[PE2-mpls] quit
[PE2] mpls ldp
[PE2-mpls-ldp] quit
[PE2] interface vlanif 30
[PE2-Vlanif30] mpls
[PE2-Vlanif30] mpls ldp
[PE2-Vlanif30] quit

    After the configuration is complete, run the display mpls ldp session command on PE1, P, and PE2. You can see that a peer relationship is set up between PE1 and P, and between P and PE2. The peer relationship is in Operational state. Run the display mpls lsp command to check the LSP status. The display on PE1 is used as an example.

    [PE1] display mpls ldp session

 LDP Session(s) in Public Network
 Codes: LAM(Label Advertisement Mode), SsnAge Unit(DDDD:HH:MM)
 A '*' before a session means the session is being deleted.
 ------------------------------------------------------------------------------
 PeerID            Status      LAM  SsnRole  SsnAge      KASent/Rcv
 ------------------------------------------------------------------------------
 2.2.2.2:0          Operational DU Passive  000:15:29   3717/3717
 ------------------------------------------------------------------------------
 TOTAL: 1 session(s) Found.

  4. Create a remote LDP session between PEs.

    # Configure PE1.

    [PE1] mpls ldp remote-peer 3.3.3.3
[PE1-mpls-ldp-remote-3.3.3.3] remote-ip 3.3.3.3
[PE1-mpls-ldp-remote-3.3.3.3] quit

    # Configure PE2.

    [PE2] mpls ldp remote-peer 1.1.1.1
[PE2-mpls-ldp-remote-1.1.1.1] remote-ip 1.1.1.1
[PE2-mpls-ldp-remote-1.1.1.1] quit

    After the configuration is complete, run the display mpls ldp session command on PE1 or PE2. You can see that the peer relationship between PE1 and PE2 is in Operational state. That is, the peer relationship is set up.

  5. Enable MPLS L2VPN on each PE.

    # Configure PE1.

    [PE1] mpls l2vpn
[PE1-l2vpn] quit

    # Configure PE2.

    [PE2] mpls l2vpn
[PE2-l2vpn] quit

  6. Configure a VSI on PEs.

    # Configure PE1.

    [PE1] vsi a2 static
[PE1-vsi-a2] pwsignal ldp
[PE1-vsi-a2-ldp] vsi-id 2
[PE1-vsi-a2-ldp] peer 3.3.3.3
[PE1-vsi-a2-ldp] quit
[PE1-vsi-a2] quit

    # Configure PE2.

    [PE2] vsi a2 static
[PE2-vsi-a2] pwsignal ldp
[PE2-vsi-a2-ldp] vsi-id 2
[PE2-vsi-a2-ldp] peer 1.1.1.1
[PE2-vsi-a2-ldp] quit
[PE2-vsi-a2] quit

  7. Bind the VSI to PE interfaces.

    # Configure PE1.

    [PE1] interface vlanif 10
[PE1-Vlanif10] l2 binding vsi a2
[PE1-Vlanif10] quit

    # Configure PE2.

    [PE2] interface vlanif 40
[PE2-Vlanif40] l2 binding vsi a2
[PE2-Vlanif40] quit

  8. Verify the configuration.

    After the configuration is complete, run the display vsi name a2 verbose command on PE1. You can see that VSI a2 sets up a PW to PE2, and the VSI status is Up.

    [PE1] display vsi name a2 verbose

  9. Configure MAC address limiting in the VSI on PE1.

    # Configure the following MAC address limiting rule in the VSI: A maximum of 300 MAC addresses can be learned. When the number of learned MAC addresses reaches the limit, the PE discards packets with new source MAC addresses and sends an alarm to the NMS.
