Requirements analysis
To ensure that the LSRs establish LSPs automatically, enable LDP on each LSR.
•
To establish LDP LSPs, configure a routing protocol to ensure IP connectivity between the LSRs. This
•
example uses OSPF.
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 Router A—Router B—Router C, configure label
acceptance policies as follows:
Router A accepts only the label mapping for FEC 21.1.1.0/24 received from Router B. Router A
denies the label mapping for FEC 21.1.1.0/24 received from Router D.
Router C accepts only the label mapping for FEC 1 1.1.1.0/24 received from Router B. Router C
denies the label mapping for FEC 1 1.1.1.0/24 received from Router D.
Configuration procedure
1. Configure IP addresses and masks for interfaces, including the loopback interfaces, as shown
in Figure
2. Configure OSPF on each router to ensure IP connectivity between them. (Details not shown.)
3. Enable MPLS and LDP:
# Configure Router A.
<RouterA> system-view
[RouterA] mpls lsr-id 1.1.1.9
[RouterA] mpls ldp
[RouterA-ldp] quit
[RouterA] interface serial 2/1/0
[RouterA-Serial2/1/0] mpls enable
[RouterA-Serial2/1/0] mpls ldp enable
[RouterA-Serial2/1/0] quit
[RouterA] interface serial 2/1/1
[RouterA-Serial2/1/1] mpls enable
