WAN Network Addresses and Long Reach Ethernet Questions

[Guest Fox1977]

Hi there,

 

Just a bit stuck on this and wondering if anyone can help me out. We

are in the process of setting up another server solution in a second

data centre. We are trying to joing to networks running on different

IP addresses using a long reach ethernet connection between the two

sites. We are in the process of getting the cabling put in but i am

not sure on the network addresses to use to connection the two.

 

We could take an address from our first solution and and put it on the

end of the LRE conenction in the data centre but that would mean

everything would be broadcast out over the lRE connection. The

company i am working with suggested setting up a private network

address range at either end of the connection.

 

I am not sure exactly how this would work. Could anyone help clarify

this. If i put 192.168.0.1 and 192.168.0.2 at either end the two

machines that are connected would be able to talk but how would the

other machines on the different addresses at either end talk? Would i

need to allocate private IPs for all of the machines on the network to

get them all to talk?

 

Should the LRE connection at our existing solution go into the 2nd

network card of one of the servers or into a switch? Bit stuck on

this as things are complicated as i think the switch has got several

different VLANs on it. If i put it into the machine directly i'm

thinking we are going to struggle to talk to anything apart from that

one.

 

Sorry for all the questions but i'm a bit stumped!

You need a router at one end of the cable - device with two NICs one on each

network.

 

I imagine that configuring RRAS on a server on each network will then set

you up.

Otherwise all computers that need to communicate with the other network

could have their routing tables configured by a logon script.

As Newell said, you do not need to change any addresses in the existing

networks. The point-to-point simply acts as a link between the sites, and

you configure the sites to route trhough the link. What devices you use to

handle the routing is up to you. You could use hardware devices, or a

machine running Windows Server with RRAS or a Linux router if you are

familiar with that. It is a pretty basic routing setup to send traffic for

the "other" site through the link.
