Hello,

are the configs of R6, R7, R8 and R9 already posted here somewhere ? With the five configurations you posted, I can ping end to end, so the problem must be with the CE routers...

[eng_adel273]

I can't ping from  R4 this commnd

ping vrf customer_1 10.0.2.9 source 172.16.1.9

aslo

in CEs , I configured only the interfaces and static route for their PE

Hi

On the CE's you should have OSPF, because that is the protocolo redistributed into the PE. Could you please share the CE config? Im going to provide you the config you should have for Customer 1

[eng_adel273]

I attached required file for all CEs

[Julio E. Moisa]

Thank you

You must replace the static route by OSPF because you are using OSPF on the PE's and making mutual redistribution between OSPF and BGP. 

Example:

CE

interface g0/0

ip address 10.0.0.2 255.255.255.252

no shutdown

router ospf 1

network 0.0.0.0 255.255.255.255 area 0

PE

ip vrf CUSTOMER1

rd 1:1

route-target import 1:1

route-target export 1:1

interface loopback 0

ip add x.x.x.x 255.255.255.255

int g0/0

ip vrf forwarding CUSTOMER1

ip add 10.0.0.1 255.255.255.252

no shutdown

router ospf 100
mpls ldp auto
network <local loopback>

network <local networks used into the ISP infrastructure>

router ospf 1 vrf CUSTOMER1

network 10.0.0.1 0.0.0.0 area 0

redistribute BGP 100 subnet

router bgp 100

--- omitting VPN config ---

address-family ipv4 vrf CUSTOMER1

redistribute OSPF 1

Hello,

I have not followed the entire thread, but try and give the loopback interfaces on R4 and R5 a /32 mask.

This is the only change I made to your original configuration, with the result being:

R4#ping vrf customer_1 10.0.2.9
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.0.2.9, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 136/184/224 ms

R5#ping vrf customer_1 10.0.1.9
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.0.1.9, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 108/142/196 ms

R4

interface Loopback1
ip address 100.0.0.5 255.255.255.255
ip ospf 1 area 0

R5

interface Loopback1
ip address 100.0.0.6 255.255.255.255
ip ospf 1 area 0
