Solved: Re: Inquiry on Best Solution for Site Connectivity

ALI12 · ‎10-01-2024

Hi Team,

Could you please advise on the best practices for the following scenario (as shown in the attached diagram)?

We have two sites connected by leased lines from two different ISPs.

What would be the best solution to ensure continuous connectivity between the sites in case one of the ISPs goes down?

Would using IP SLA with static routes or OSPF HA be more effective or anything else?

Hello
you do not mention what type is circuit you have - l2/l3vpn - internet ?
Do you have administrative control of the rtrs at both sites?
if you can run any routing process - i would say for fastest convergence invoke eigrp ( if you are running all cisco) plus it supports unequal load balancing
Ospf if you have mutu-vendor hardware it’s not as fast as eigrp but i’d say is better for segmentation of your network and path manipulation
BGP is the overall best routing process - it not designed for fast convergence but is the best in terms of traffic control -best path determination - stability

If you can elaborate a little further on your network -expectations maybe a recommendion could be provided?

Please rate and mark as an accepted solution if you have found any of the information provided useful.
This then could assist others on these forums to find a valuable answer and broadens the community’s global network.
