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 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
