Hello

Can you elaborate a little more-

Are you wanting inter-site traffic prefer to route west-east & east-west and use each sites  isp connection for internet traffic and for site-site resiliency.

What type of isp service is being provided to the sites,( ethernet, gre/ipsec/mpls/vpls, etc..)

Hi,

the type of isp  is ethernet.

thank u

Hello,

post the zipped Packet Tracer project (.pkt) file.

As for the subnetting, if you need to use the range 209.168.16.0/16, you can subnet into 4 subnets and use three of them for the inter-ISP and the Router-to-ISP links:

Subnet: 209.168.16.64/26
Host Address Range: 209.168.16.1 - 209.168.16.62

Subnet: 209.168.16.0/26
Host Address Range: 209.168.16.65 - 209.168.16.126

Subnet: 209.168.16.128/26
Host Address Range: 209.168.16.129 - 209.168.16.191

Subnet: 209.168.16.192/26
Host Address Range: 209.168.16.193 - 209.168.16.254

Dag Georg,

Tussen de 2 links van de ISP's krijg ik nog steeds Ip overlaps

Wat doe ik fout?

[Georg Pauwen]

Hello,

I have configured the serial links between your ISPs, and between the ISPs and routers 5 and 6, using different subnets. Find attached the revised file.
