can someone help me out with the following scenario
I am new to OSPF, so bare with me.
My eth1 faces the internet with a public IP (several) my customers are natted to their cpe wlan, and then again natted across to various public IP's in the gateway according to their service type.
Eth2 has an address in the range 12.1.0.0/24 and Eth3 has an address in the range 13.1.0.0/24
Routers are seperated by IP ranges at present, both clockwise and anticlockwise as far as point Z... Eg 12.1.1.x - 12.1.10.x clockwise. And antiiclockwise 13.1.1.x - 13.1.10.x
everything is routed back to the gateway, however at point Z I have to choose between one direction or the other
Having closed the remaining segmant in my loop.. I want to try more advanceed things with OSPF.
Starting with redundancy and maybe splitting the load across the 2 halves.
I am about to change the entire structure to one address range in blocks of /30.... All same range, say 10.1.x.x
Forgetting the stubs and the more mundain stuff,
OSPF must be set in R1 to redistribute default, correct!!
And in both R2 and R3, they must be set to Redistribute connected only (as well as all others)
And the entire loop is same network 10.1.0.0/24 to encompass all /30 blocks.
The loop is also called the same name "backbone" . Each RB will have a "loopback" with a /32 address added into the ospf routes.
My question is right back at R1, I am confused I cannot have 2 Ip's in the same range across seperate interfaces, I also do not want to use a bridge. I can of course segment both Eth2 and Eth3 by a /30 block.
So when install OSPF on the gateway, do I install OSPF to run on ALL interfaces (eth2 and 3) or do I have 2 seperate instances of OSPF running.. Open one tab and run it on Eth2 and open a second tab and run another service on eth3
Maybe I am just thinking too hard.
Anyone !
