Config Guidelines
****************************************************************************************
Scenario - Providing Internet Access to MPLS VPN Cusomer using Route-Leaking via Global
Internet Table with using NAT for the Customer's Private IP Block used for Internet.
NAT being done at the PE ROuter Peering with Internet. In this design we need to propogate the
Private IP Block Route till the Internet Peering Router to have reachability Locally in Provider AS
ISP AS used 64513
IGP in ISP is ISIS with Loopbacks in Level-1 and Core Links in Level-2
EBGP used with Internet Router
Customer AS Used 64514
PE-CE Routing Protocol EBGP
Internet AS 64515
Lo0 and Lo1 used for Dummy Traffic
VRF Used CEA
rd 64513:1
rt 6413:100
CE1B is Normal IP Customer in AS 64516 running EBGP with PE2
CE1A and CE2A are VPN Sites with CE1A only having Internet Access.
Used NAT Inside on Serial1/0 at PE1 and NAT Outisde on Core Link Serial1/1towards P
NAT Pool Used GRE_Internet 192.168.1/0/30
Extended ACL used 134 Denying 10.0.1.1/32 and Allowing 192.168.100.0/24
CE1A has a default Route towards PE1 via Serial1/0
ANy Non-VPN Traffic from CE1A comes to PE1 via Serial1/0 and get Natted Outbound to
192.168.1.1 and Goes to Internet Router Internet Router has Reverse Route till PE1
for 192.168.1.1 and from there Reverse NAT Happens towards CE1A
