request, LSR5 takes out MPLS label and sends this echo request
packet to LSR6 as a common IP packet. After receiving this echo
request packet, LSR6 processes echo request and returns an MPLS
echo reply packet with return value to be 3 to LSR1 along the re-
verse path. In this way, LSR1 can learn LSR addressees that LSR
passes.
8900 series switches can use LSP TRACE/PING function to detect
FEC (IPV4 UDP and RSVP) of various types. LSP TRACE/PING re-
quest packet is a tagged UDP packet. As for this packet, the desti-
nation port is the well-known port 3503 and source port is specified
by sender. Source address in IP layer is IP address of sender, des-
tination address is 127.x.x.x/8, and TLV field contains downstream
TLV to store label information for showing label information when
1SP TRACE/PING succeeds.

Configure MPLS OAM

Network node or link fault can be analyzed by executing command
TRACE/PING.

Parameters:
Function
This enables/disable
show icmp debugging
information function
in global configuration
mode. When the
function is enabled,
basic information
of this echo packet
can be shown when
router sends or
receives an MPLS
echo packet. The
function is disabled by
default.
Function
This checks LDP of
IPV4 and FEC of RSVP
in privileged mode.
