After the configuration, LDP sessions are set up between the adjacent nodes. Run the display
mpls ldp session command on each node. The Status is Operational.
In the following example, the display on P1 is used.
<P1> 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
------------------------------------------------------------------------------
2.2.2.9:0
3.3.3.9:0
------------------------------------------------------------------------------
TOTAL: 2 session(s) Found.
Step 3 Enable synchronization between LDP and IGP on the P1 and P2 interfaces.
# Configure P1.
<P1> system-view
[P1] interface gigabitethernet 1/0/0
[P1-GigabitEthernet1/0/0] ospf ldp-sync
[P1-GigabitEthernet1/0/0] quit
# Configure P2.
<P2> system-view
[P2] interface gigabitethernet 1/0/0
[P2-GigabitEthernet1/0/0] ospf ldp-sync
[P2-GigabitEthernet1/0/0] quit
Step 4 Set a value for the hold-down timer on the P1 and P2 interfaces.
# Configure P1.
<P1> system-view
[P1] interface gigabitethernet 1/0/0
[P1-GigabitEthernet1/0/0] ospf timer ldp-sync hold-down 8
[P1-GigabitEthernet1/0/0] quit
# Configure P2.
<P2> system-view
[P2] interface gigabitethernet 1/0/0
[P2-GigabitEthernet1/0/0] ospf timer ldp-sync hold-down 8
[P2-GigabitEthernet1/0/0] quit
