Recently, i've been configuring a router as a frame relay switch, well everything is ok, since then i had some ideas i was thinking about, does the serial interfaces in the frame relay switch support or can have IP addresses configured in? I can see in many searches that all serial interfaces ports in a frame relay switch are set to "no ip address", ok, now if i have a company that have 3 offices:
1 office in New York, US.
1 office in Paris, France.
1 office in Tokyo, Japan.
How can the ISP in new york link or map the router i have with the frame relay switch of the France ISP and Japan ISP?
My question is: Does serial interfaces in a frame relay switch have ip addresses so the other ISP can map based on these public IP addresses? Or What is the method to make these links between different ISPs using Frame Relay. Or Frame Relay will not be the best WAN network solution since the offices doesn't exist in the same territory? no?
I'll be happy to hear from you Experts, your experiences in this matter.
Thank you alot.
