How to Configure MPLS VPNs over IP Tunnels

 

Command or Action

Purpose

Step 5

 

 

ipv6 address 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

 

RP/0/RP0/CPU0:router(config-if)# ipv6

using 16-bit values between colons, as follows:

 

100::1:10:2/64

IPv6 name or address: Hostname or X:X::X%zone

 

 

 

 

IPv6 prefix: X:X::X%zone/<0-128>

Step 6

 

 

dot1q native vlan vlan-id

Enters the trunk interface ID. Range is from 1 to 4094

 

 

inclusive (0 and 4095 are reserved).

 

Example:

 

 

RP/0/RP0/CPU0:router(config-if)# dot1q native

 

 

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)?

 

RP/0/RP0/CPU0:router(config-if)# end

[cancel]:

 

 

 

or

Entering yes saves configuration changes to the

 

RP/0/RP0/CPU0:router(config-if)# commit

 

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
