6VPE

my network diagram for 6VPE

what is 6VPE ?

IPv6 VPN Network through MPLS IPv4 network

for this topology I use IOS c7200-adventerprisek9-mz.122-33.SRC1.bin i need feature vpnv6 in BGP extension

1.create vrf vpnv6_a & vpnv6_b

2. Network VPN must overlap

3. use sonet interface for backbone

here configuration for PE1

Use vrf definition command to create vrf vpnv6_a & vpnv6_b

you must activate address family ipv6 for ipv6 vpn support

!

vrf definition vpnv6_a
rd 777:1
route-target export 777:1
route-target import 777:1
!
address-family ipv4
exit-address-family
!
address-family ipv6
exit-address-family
!
vrf definition vpnv6_b
rd 777:2
route-target export 777:2
route-target import 777:2
!
address-family ipv4
exit-address-family
!
address-family ipv6
exit-address-family
!

Activate ipv6 unicast routing

!
ip cef
ipv6 unicast-routing
ipv6 cef
!

Configure Loopback Interface

!

interface Loopback0
ip address 202.162.208.1 255.255.255.255
!
interface FastEthernet0/0
no ip address
shutdown
duplex half
!

Activate MPLS using command mpls ip on PE to backbone interface

interface POS1/0

ip address 202.162.208.5 255.255.255.252
mpls ip
!

Configure vrf forwarding on PE to CE Interface In different vrf name you can configure IP overlap with other vrf for example interface in vrf vpnv6_a have the same IPv6 address with vrf vpnv6_b

!
interface FastEthernet2/0
vrf forwarding vpnv6_a
no ip address
speed auto
duplex auto
ipv6 address 2001:5C0:1::1/126
!
interface FastEthernet2/1
vrf forwarding vpnv6_b
no ip address
speed auto
duplex auto
ipv6 address 2001:5C0:1::1/126
!

Activate IGP between PE to P router

!

router ospf 1
log-adjacency-changes
network 202.162.208.0 0.0.0.255 area 0
!

Configure MP-BGP

router bgp 777

bgp log-neighbor-changes
neighbor 125.126.46.1 remote-as 777
neighbor 125.126.46.1 update-source Loopback0
!
address-family ipv4
no synchronization
redistribute static
neighbor 125.126.46.1 activate
neighbor 125.126.46.1 next-hop-self
no auto-summary
exit-address-family
!
address-family vpnv4
neighbor 125.126.46.1 activate
neighbor 125.126.46.1 send-community both
exit-address-family
!
address-family vpnv6
neighbor 125.126.46.1 activate
neighbor 125.126.46.1 send-community both
exit-address-family
!
address-family ipv4 vrf vpnv6_a
no synchronization
redistribute static
exit-address-family
!
address-family ipv6 vrf vpnv6_a
redistribute static
no synchronization
exit-address-family
!
address-family ipv4 vrf vpnv6_b
no synchronization
redistribute static
exit-address-family
!
address-family ipv6 vrf vpnv6_b
redistribute static
no synchronization
exit-address-family

Create IPv6 static route in VRF vpnv6_a & vpnv6_b with destination to CE router

!

ipv6 route vrf vpnv6_b 2001:D30:7::/64 2001:5C0:1::3
ipv6 route vrf vpnv6_a 2001:D30:7::/64 2001:5C0:1::3
!

for P router configure each interface with mpls ip and global IPv4 IGP

!
interface Loopback0
ip address 202.162.208.2 255.255.255.255
!
interface FastEthernet0/0
no ip address
shutdown
duplex half
!
interface POS1/0
ip address 202.162.208.6 255.255.255.252
mpls ip
!
interface POS2/0
ip address 202.162.208.254 255.255.255.252
mpls ip
!
router ospf 1
log-adjacency-changes
network 202.162.208.0 0.0.0.255 area 0
!
ip classless
!


troubleshoot it

now we check the packet passing P Router
