Implementing MPLS VPNs over IP Tunnels on Cisco IOS XR Software
How to Configure MPLS VPNs over IP Tunnels
| Command or Action | Purpose |
Step 5 |
|
|
ipv6 address | Enters an IPv6 address. | |
|
| This argument must be in the form documented in |
| Example: | RFC 2373, where the address is specified in hexadecimal |
| using | |
| 100::1:10:2/64 | • IPv6 name or address: Hostname or X:X::X%zone |
|
| |
|
| • IPv6 prefix: |
Step 6 |
|
|
dot1q native vlan | Enters the trunk interface ID. Range is from 1 to 4094 | |
|
| inclusive (0 and 4095 are reserved). |
| Example: |
|
|
| |
| vlan 665 |
|
Step 7 |
|
|
end | Saves configuration changes. | |
| or | • When you issue the end command, the system prompts |
|
| |
| commit | you to commit changes: |
|
| Uncommitted changes found, commit them before |
| Example: | exiting(yes/no/cancel)? |
| [cancel]: | |
|
| |
| or | – Entering yes saves configuration changes to the |
| ||
| running configuration file, exits the configuration | |
|
| session, and returns the router to EXEC mode. |
|
| – Entering no exits the configuration session and |
|
| returns the router to EXEC mode without |
|
| committing the configuration changes. |
|
| – Entering cancel leaves the router in the current |
|
| configuration session without exiting or |
|
| committing the configuration changes. |
|
| • Use the commit command to save the configuration |
|
| changes to the running configuration file and remain |
|
| within the configuration session. |

Configuring the Core Network
To configure the core network, refer to the procedures documented in Implementing MPLS Layer 3 VPNs on Cisco IOS XR Software.
The tasks are presented as follows:
•Assessing the needs of MPLS VPN customers
•Configuring routing protocols in the core
•Configuring MPLS in the core
•Enabling FIB in the core
•Configuring BGP on the PE routers and route reflectors
