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

!

!

Configure MP-BGP

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
!

troubleshoot it

now we check the packet passing P Router

MPLS VPN IPv4

hai everybody i am back, long time no see
its time for me to continue posting about networking
maybe starting this time and next time i wilL posting about MPLS Network
now its about MPLS VPN IPv4








this is my first MPLS lab using GNS 3

how about the rule ???
1. don't use sub interface on serial interface PE-CE1
2. create vrf name vpn_1 & vpn_2
3. network PE-CE must overlap ecah other
example PE-CE1 must overlap PE-CE2
4.use rip for PE-CE
5.use ospf for backbone router

and this is sample configuration for PE1

create vrf for vpn_1 & vpn_2
this configuration is mandatory configured

ip vrf vpn_1
rd 777:1
route-target export 777:1
route-target import 777:1
!
ip vrf vpn_2
rd 777:2
route-target export 777:2
route-target import 777:2

configure loopback interface you must configure IP with /32 prefix

interface Loopback0
ip address 202.162.208.1 255.255.255.255


configure interface to backbone network in cisco 3640 you can use tag switching ip or mpls ip command

finish configuration for PE

for P router

Activate tag switching or mpls IP and global IGP

now let's troubleshoot them

you can use show mpls forwarding table command









let's check it with traceroute

for the next post i will posting MPLS IPv6 or 6VPE

Interworking BGP Cisco with Juniper

this is my new BGP lab


with combining Cisco dynamips and Olive Junos using Logical router to prevent Olive multiple folder
this Lab running on FreeBSD 7.1
and the scenario

1. Since I've got trouble with OSPF on my QEMU so I use static route for IBGP peering
2. Use BGP regular expression for advertise route with no AS-path at R2
3. Change the origin route advertised out at R2
4. Set network originate 192.168.0.0/16 as Primary and 172.17.0.0/16 as Backup at R3 and vice versa at LR-1
5. Use BGP confederation on AS 8000
6. Set loadbalance on AS 2500

this lab contains
1. BGP loadbalancing
2. MED, Localpreference, regular expression tuning
3. BGP confederation
4. BGP prepending

Traceroute my PC

















Traceroute logical router

















#sh ip bgp at R2


















#sh ip bgp at R4

















root#run show route LR-4

















root#run show route LR-7















if you want to see my configuration you can download from

for the next post maybe i will post multicast IPv6 routing using XORP (eXtensible Open Router Platform)
