HP 6127xlg Configuration Manual page 50

To ensure that LDP establishes LSPs only for the routes 1 1.1.1.0/24 and 21.1.1.0/24, configure LSP
•
generation policies on each LSR.
To ensure that LDP establishes LSPs only over the link Switch A—Switch B—Switch C, configure label
•
acceptance policies as follows:
Switch A accepts only the label mapping for FEC 21.1.1.0/24 received from Switch B. Switch A
denies the label mapping for FEC 21.1.1.0/24 received from Switch D.
Switch C accepts only the label mapping for FEC 1 1.1.1.0/24 received from Switch B. Switch C
denies the label mapping for FEC 1 1.1.1.0/24 received from Switch D.
Configuration procedure
1. Configure IP addresses and masks for interfaces, including the loopback interfaces, as shown
in Figure
2. Configure OSPF on each switch to ensure IP connectivity between them. (Details not shown.)
3. Enable MPLS and LDP:
# Configure Switch A.
<SwitchA> system-view
[SwitchA] mpls lsr-id 1.1.1.9
[SwitchA] mpls ldp
[SwitchA-ldp] quit
[SwitchA] interface vlan-interface 2
[SwitchA-Vlan-interface2] mpls enable
[SwitchA-Vlan-interface2] mpls ldp enable
[SwitchA-Vlan-interface2] quit
[SwitchA] interface vlan-interface 6
[SwitchA-Vlan-interface6] mpls enable
[SwitchA-Vlan-interface6] mpls ldp enable
[SwitchA-Vlan-interface6] quit
# Configure Switch B.
<SwitchB> system-view
[SwitchB] mpls lsr-id 2.2.2.9
[SwitchB] mpls ldp
[SwitchB-ldp] quit
[SwitchB] interface vlan-interface 2
[SwitchB-Vlan-interface2] mpls enable
[SwitchB-Vlan-interface2] mpls ldp enable
[SwitchB-Vlan-interface2] quit
[SwitchB] interface vlan-interface 3
[SwitchB-Vlan-interface3] mpls enable
[SwitchB-Vlan-interface3] mpls ldp enable
[SwitchB-Vlan-interface3] quit
# Configure Switch C.
<SwitchC> system-view
[SwitchC] mpls lsr-id 3.3.3.9
[SwitchC] mpls ldp
[SwitchC-ldp] quit
[SwitchC] interface vlan-interface 3
[SwitchC-Vlan-interface3] mpls enable
