PurposeCommand 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
