Purpose
Command or Action
Directs the system to accept targeted hello messages from any source
and activates passive mode on the LSR for targeted hello acceptance.
discovery targeted-hello accept
Example:
RP/0/RP0/CPU0:router(config-ldp)#
discovery targeted-hello accept
Step 4
•
This command is executed on the receiver node (with respect
to a given MPLS TE tunnel).
•
You can control the targeted-hello acceptance using the
discovery targeted-hello accept
command.
commit
—
Saves the configuration changes and remains within the
configuration session.
Use the
commit
or
end
command.
Step 5
end
—
Prompts user to take one of these actions:
•
Yes
—
Saves configuration changes and exits the configuration
session.
•
No
—
Exits the configuration session without committing the
configuration changes.
•
Cancel
—
Remains in the configuration session, without
committing the configuration changes.
(Optional)
Displays the status of the LDP discovery process. This command,
without an interface filter, generates a list of interfaces over which
show mpls ldp discovery
Example:
RP/0/RP0/CPU0:router#
show mpls ldp
discovery
Step 6
the LDP discovery process is running. The output information contains
the state of the link (xmt/rcv hellos), local LDP identifier, the
discovered peer
’
s LDP identifier, and holdtime values.
(Optional)
Displays the status of the LDP discovery process for the specified
VRF.
show mpls ldp vrf vrf-name discovery
Example:
RP/0/RP0/CPU0:router#
show mpls ldp vrf
red discovery
Step 7
(Optional)
Displays the summarized status of the LDP discovery process for all
VRFs.
show mpls ldp vrf all discovery summary
Example:
RP/0/RP0/CPU0:router#
show mpls ldp vrf
all discovery summary
Step 8
(Optional)
Displays the brief status of the LDP discovery process for all VRFs.
show mpls ldp vrf all discovery brief
Example:
RP/0/RP0/CPU0:router#
show mpls ldp vrf
all discovery brief
