Hi Rene,
My goal is to access Internet (viz google.com/cisco.com e.t.c.) over MPLS VPN Network.
I had a below scenario copied from you.
Final target is to access Internet on AS3 by Windows10 PC on AS1 over MPLS VPN Network.
- I configured eBGP between PE-CE
- Configured ospf as IGP
- Created a VRF “Internet”
- Configured iBGP between PE1-PE2
- Created a static route on CE1 for accessing internet
- Advertised L0 : 5.5.5.5/32 & 192.168.184.0/24 into BGP on CE2 Router
Verification
==========
PE1#sh ip route vrf Internet
Routing Table: Internet
Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
E1 - OSPF external type 1, E2 - OSPF external type 2
i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2
ia - IS-IS inter area, * - candidate default, U - per-user static route
o - ODR, P - periodic downloaded static route
Gateway of last resort is not set
**C 192.168.12.0/24 is directly connected, FastEthernet0/0**
** 5.0.0.0/32 is subnetted, 1 subnets**

CE1#sh ip bgp
BGP table version is 4, local router ID is 1.1.1.1
Status codes: s suppressed, d damped, h history, * valid, > best, i - internal,
