Hi,
I'll try to give more information about my network.
I plan to do this because of future expansion and high availability.
On picture, which simplifies my core backbone but for this lets take it as it shown, you can see 'my plan':
Current situation:
Behind every core router I have lots of other boards and few OSPF areas.
I use
private address space on my network and I EoIP every CPE to my central location where I bridge them and use hotspot for authentication. Every user gets
public IP address.
Plan:
My plan is to add two more gateways. On core routers 2 ad 3.
Because of that I must setup hotspot on every AP (remove central hotspot setup) so that users can go out any of available gateways.
I want to use all advantages from that setup as tomaskir mentioned.
I want that my users go trough another gateway if one fail (the main reason).
I want them also to go to Internet trough closest one if active because of latency.
I want good load balancing over multiple gateways (I have good connectivity over my core network).
Main questions are (i think
):
Can I stay on private address space across my network? Just propagate private IP network information to my gateway routers. Good and bad side of this setup?
Is OSPF locally and BGP on gateway routers good way to go?
Or just stay on current setup and have only one gateway?
Thx all.
