Hai, need ur profesional advised,
i have 1 core router that connected to 3 ISP and 5 customer with differ capacity
cust1-ISP1-2M
cust2-ISP1-4M
cust3-ISP2-stm1
cust4-ISP3-45M
cust5-ISP3-8M
1. do i need edge router that will interconnect to my customer. can i directly connect to my core router?
2. all routing to ISP is static route. ist possible
3.how can i manage the bandwith as different customer and different isp. is there a way i can have this via policy.
4. do i need to dedicate one customer to one router port, is there a way i can shared everything and save my port expecially E1 port which is expensive?
I really need your answer and help.. iam alone..i already try searching but nothing close.
please my frenz. TQ in advanced!

1. Either u get a separate edge router or WIC ports for each customer.
2. Use separate VRF instances for each customer. This way u can manage with static routes.
3. U can police the bandwidth on each interface to restrict it to the required value.

1. Either u get a separate edge router or WIC ports for each customer. --> can i have multiple customer with different bandwith req and prefered isp into one edge router.
2. Use separate VRF instances for each customer. This way u can manage with static routes. --> even if my network is not MPLS i can run VRF?
3. U can police the bandwidth on each interface to restrict it to the required value.--> this interface referring to edge router interface? or core router interface?
TQ

Hi
Looking at your original requirement one core router will do, you can directly connect your customers, no mpls or vrf lite required.
Just use PBR and policing.
Please note I thumb sucked most of the values and you should LAB test this first.
Keep in mind NAT might also be a requirement, depending on your addressing scheme.
Depending on your router hardware the config should look something like this:
#CUST1 ip range
access-list 1 permit 192.168.1.0 0.0.0.255
#CUST2 ip range
access-list 2 permit 192.168.2.0 0.0.0.255
#CUST3 ip range
access-list 3 permit 192.168.3.0 0.0.0.255
#CUST4 ip range
access-list 4 permit 192.168.4.0 0.0.0.255
#CUST5 ip range
access-list 5 permit 192.168.5.0 0.0.0.255

Hai..thanks phillip,
my network design ok? and i can connect directly to my core. no need mpls and vrf.
fyi..i didnt have control on the ip address , it will given by upstream provider to our customer. we only handle the routing from our customer to their respective isp. so..is this configuration suitable also with my scenario?... TQ

any comment and idea... i will consider it TQ

Hi
Sorry, been out of the office.
Yes the configuration is suitable with your scenario, you just need to mark cust IP addresses provided by the ISP with the ACL.
As for bringing it in to your core, it will work but not best practise, this all depends on the requirements and feasibility of adding a dedicated edge box. Either way no mpls or vrf required.
