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..) 


Please rate and mark as an accepted solution if you have found any of the information provided useful.

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?

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.

Hello, 

 

What version of packet tracer are u using? because its not compatible with mine.  What u send I cant open.

kind regards

Hello.

 

I have version 7.3.1.

 

Either way, here are the relevant interface configs:

ip address 209.168.16.65 255.255.255.192
!
interface Serial0/0/1
ip address 209.168.16.1 255.255.255.192
clock rate 2000000

 

Backup ISP

interface Serial0/0/0
ip address 209.168.16.129 255.255.255.192
!
interface Serial0/0/1
ip address 209.168.16.2 255.255.255.192

 

Router 5

interface Serial0/0/0
ip address 209.168.16.66 255.255.255.192
clock rate 2000000

 

Router 6
