Cisco CRS Configuration Guide

PurposeCommand or Action
Enters MPLS-TE interface configuration mode and enables traffic
engineering on a particular interface on the originating node.
interface type interface-path-id
Example:
RP/0/RP0/CPU0:router(config)#
Step 2
interface POS0/6/0/0
Specifies a primary or secondary IPv4 address for an interface.
ipv4 address ipv4-address mask
Step 3
Example:
RP/0/RP0/CPU0:router(config-if)# ipv4
•
Network mask can be a four-part dotted decimal address. For
example, 255.0.0.0 indicates that each bit equal to 1 means that the
corresponding address bit belongs to the network address.
address 192.168.1.27 255.0.0.0
•
Network mask can be indicated as a slash (/) and a number (prefix
length). The prefix length is a decimal value that indicates how many
of the high-order contiguous bits of the address compose the prefix
(the network portion of the address). A slash must precede the
decimal value, and there is no space between the IP address and the
slash.
Exits the current configuration mode.exit
Example:
RP/0/RP0/CPU0:router(config-if)# exit
Step 4
RP/0/RP0/CPU0:router(config)#
Configures an Open Shortest Path First (OSPF) routing process. The
process name is any alphanumeric string no longer than 40 characters
without spaces.
router ospf process-name
Example:
RP/0/RP0/CPU0:router(config)# router
Step 5
ospf 1
RP/0/RP0/CPU0:router(config-ospf)#
Specifies that the TE router identifier for the node is the IP address that
is associated with a given interface. The router ID is specified with an
mpls traffic-eng router-id type
interface-path-id
Step 6
interface name or an IP address. By default, MPLS uses the global router
ID.
Example:
RP/0/RP0/CPU0:router(config-ospf)#
mpls traffic-eng router id Loopback0
commit—Saves the configuration changes and remains within the
configuration session.
Use the commit or end command.
Step 7
end—Prompts user to take one of these actions:
• Yes— Saves configuration changes and exits the configuration
session.
