Configuration Flow
1. Build an LDP network.
2. Perform LDP LSP ping on R1.
l Configuration Commands
For LDP configuration, refer to the MPLS configuration example.

Configuration Verification
Ping R3 on R1. The result is displayed as follows:
R1#ping mpls ipv4 10.28.0.4 32
sending 5,120-byte MPLS echo(es) to 10.28.0.4,timeout is 2 second(s).
Codes: '!' - success,
ut,
ismatch,
label,
wn return code, 'x' - return code 0
!!!!!
Success rate is 100 percent(5/5),round-trip min/avg/max= 5/38/151 ms.
Ping R3 (unmatching FEC) on R1. The result is displayed as follows:
R1#ping mpls ipv4 10.28.0.4 30
sending 5,120-byte MPLS echo(es) to 10.28.0.4,timeout is 2 second(s).

Figure 15-10, LDP is enabled on R1, R2 and R3. It is required to configure
'L' - labeled output interface, 'B' - unlabeled output interface,
'D' - DS Map mismatch,
'M' - malformed request,
'P' - no rx intf label prot,
'R' - transit router,
'd' - DDMAP

'Q' - request not sent,
'F' - no FEC mapping,
'm' - unsupported tlvs,
'p' - premature termination of LSP,
'I' - unknown upstream index, 'X' - unkno
