PurposeCommand or Action
Enables the loopback interface and enters interface configuration
mode.
interface loopback interface-number
Example:
Router(config)# interface loopback 1
Step 3
Specifies the IP address and subnet mask for this loopback
interface.
ip address ip-address mask [secondary]
Example:
Router(config)# ip address 10.1.1.1
255.255.255.255
Step 4
Reserves a loopback interface used as source for the CESoPSN
circuit.
cemoudp reserve bay bay-number
Example:
Router(config-if)# cemoudp reserve bay 1
Step 5
• bay bay-number—Specifies the bay on the module.
Creates a new pseudowire class and enters pseudowire-class
configuration mode.
pseudowire-class pseudowire-class-name
Example:
Router(config-if)# psuedowire-class PS1
Step 6
Specifies the UDP transport protocol.encapsulation udp
Example:
Router(config-pw-class)# encapsulation udp
Step 7
Configures the IP address of the provider edge (PE) router
interface as the source IP address for sending tunneled packets.
ip local interface loopback interface-number
Example:
Router(config-pw-class)# ip local interface
loopback 1
Step 8
Specifies the type of service (ToS) level for IP traffic in the
pseudowire.
ip tos value number
Example:
Router(config-pw-router)# ip tos value 23
Step 9
Specifies a value for the time-to-live (TTL) byte in the IP headers
of Layer 2 tunneled packets.
Configuration of IP TTL 1 is not
supported.
Note
ip ttl number
Example:
Router(config-pw-class)# ip ttl 32
