IPv6 MPLS 6VPE Carrier Supporting carrier with Customer Carrier Running MPLS and IPv6 Links between ISPs LAB

Design Considerations for Carrier Supporting Carrier with Customer Carrier and Backbone Carrier both runing MPLS-

Ipv6 and IPv6 Link between ISPs
*******************************************************************************************************************

*

Customer Carrier should create a dedicated VRF for peering with Backbone Carrier and should import/export the CE's

RTs as needed in the backbone provider VRF

Backbone Carrier should create a dedicated VRF for peering with Customer Carrier and RT is independent of Customer

Carrier For backbone carrier Customer Carrier is just a CE.

Peering between Customer Carrier and Backbone carrier is IPv6

Using next-hop-self feature for address-family vpnv6 BGP sessions in Customer Carrier and address-family ipv6

between customer carrier and backbone carrier.

Using redistribute connected at all ISP Peering points for reachability.

Backbone Carrier-Customer Carrier Links are IPv6

Using Route-Map with Community-List and As-path Access-List in Backbone Carrier to allow only Customer VPN ROutes to Customer Carrier.

Using Route-Map with As-path Access-List in Customer Carrier to allow only Customer VPN ROutes to Customer .

Data Flow
**************
CE1A-PE1C over IPv6 EBGP
PE1c-PE2c over vpnv6 MP-iBGP
PE2C-PE1B over any relevant Ipv6 PE-CE Routing Protocol (Static/EBGP)
PE1B-PE2B over vpnv6 MP-iBGP
PE2B-PE3C over any relevant Ipv6 PE-CE Routing Protocol (Static/EBGP)
PE3c-PE4c over vpnv6 MP-iBGP
PE4C-CE2A over IPv6 EBGP


*****************************************
Configuration Guidelines

Customer Carrier VRF used for CEA is CEA
rd 64513:1
rt 64513:100

Backbone Carrier VRF used for Customer Carrier is ISPA
rd used 64515:1
rt 64515:100

PE-CE for Customer Carrier is EBGP
IGP for Customer Carrier is ISIS. PE1C & PE2C and PE3C & PE4C in different area and loopbacks in level-1.
PE-CE for Backbone carrier is EBGP
IGP for Backbone Carrier is ISIS.PE1B & PE2B in different area and loopbacks in level-1

CE AS 64514

Backbone Carrier Community-List used
Community standard list 14
permit 64515:14


Backbone Carrier AS-Path Access-List used
AS path access list 13
permit 10 _64513_
AS path access list 14
permit _64514$

Customer Carrier AS-Path Access-List used
AS path access list 13
deny ^$
AS path access list 14
permit _64514_

Route-Map Used in Backbone Carrier to Customer Carrier
CEA Inbound
CEA_OUT Outbound

Route-Map Used in Customer Carrier to CEs
CEA_OUT Outbound
