Implementing MPLS VPNs over IP Tunnels
Enters Global Configuration mode.
Step 2
interface type interface-path-id
Example:
RP/0/RP0/CPU0:router(config)# interface Loopback0
Enters interface configuration mode and enables a Loopback interface.
Step 3
ipv4 address ipv4-address
Example:
RP/0/RP0/CPU0:router(config-if)# ipv4 address 1.1.1.1 255.255.255.255
Enters an IPv4 address and mask for the associated IP subnet. The network mask can be specified in either of two ways:
• The 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.
• The network mask can be indicated as a slash (/) and number. For example, /8 indicates that the first 8 bits of the
mask are ones, and the corresponding bits of the address are the network address.
Step 4
Use the commit or end command.
commit - Saves the configuration changes and remains within the configuration session.
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 mode, without committing the configuration changes.
