Enable Multicast Support for MPLS VPN

this is my new topology, enabling multicast support for MPLS VPN










recently i thought how to enable multicast support on MPLS VPN until finally found articel from cisco so i try it

this is the configuration for PE Router


!--- Configure VRF, Route Distinguser (RD) to allow IP overlaping
!--- Configure the default Multicast Distribution Tree (MDT)
!--- for VRF vpn1 & vpn2

!

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

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

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
