DXS-3600 Series 10GbE Layer 2/3 Switch CLI Reference Guide
351
38-15 ldp router-id
This command is used to set the LSR ID of the LDP. Use no ldp router-id command to restore the LSR ID to default
value.
ldp router-id IP-ADDRESS
no ldp router-id
Parameters
38-16 transport-address
This command is used to set the global transport address. Use the no form of this command to restore the default
value.
transport-address {interface | IP-ADDRESS}
no transport-address
Command Mode
MPLS Targeted Peer Configuration Mode.
Command Default Level
Level: 15.
Usage Guideline
It is necessary to ensure that the hold-time of the target hello is larger than the
interval value. Otherwise, LDP can not work normally according to the requirement.
Example
This example shows how to configure the LDP extended discovery hello hold time to
90 seconds for targeted peer 110.10.10.1.
DXS-3600-32S#configure terminal
DXS-3600-32S(config)# mpls ldp targeted-peer 110.10.10.1
DXS-3600-32S(config-mpls-targeted-peer)# target-hello holdtime 90
DXS-3600-32S(config-mpls-targeted-peer)#
IP-ADDRESS Specifies the IPv4 address that will be used as LSR ID. The IPv4 address must be
an IP address of an existing interface.
Default
The LSR ID will be selected according the following rules:
1 If a loopback interface is configured, the LSR ID is set to the IP address of the
loopback interface. If multiple loopback interfaces are configured, the loopback
with the highest IP address will be used.
2 If no loopback interface is configured, the LSR ID is set to the highest IP address
of the link-up interfaces.
3 If no interface is link-up, the LSR ID is set to the highest IP address of the
interfaces.
Note: If LDP is running, LSR ID will not be auto-changed.
Command Mode
MPLS Router Configuration Mode.
Command Default Level
Level: 15.
Usage Guideline
The LSR ID is used to identify the LSR in the MPLS network. It is recommended to
set the LSR ID to the IP address of a loopback interface. The value of the LSR ID
should be globally unique. By default, the LSR ID is used as the transport-address. It
is necessary to ensure that the LSR ID is route reachable for other LSRs. Note: If
LDP is running, configuring the LSR ID will lead to an LDP restart.
Example
This example shows how to configure the LDP LSR ID to 110.10.10.30.
DXS-3600-32S#configure terminal
DXS-3600-32S(config)# mpls label protocol ldp
DXS-3600-32S(config-mpls-router)# ldp router-id 110.10.10.30
DXS-3600-32S(config-mpls-router)#
