FR Hub and Spoke

I'm created a frame relay network, what do I need to do to make it into a hub and spoke network?  I was thinking of making London the hub.  Would I just remove DLCI 203 from New Youk and 302 from Tokyo?

    Hi Gonzo,


    The DLCI mapping between newyork and tokyo are used to reach eachother,if it is a hub-to-spoke topology then both reach via LONDON or else if u configure one dedicated link bettween them in frame relay cloud ,so if u have dedicated framerelay line between them configured in framrelay ,remove it then this will become hub-to-spoke topology,

    HI Guys, So fresh and new on this forum, Anyway you're right right for Hub and spoke you can remove 203/302 dlci otherwise this topology would likely be a  point to point connectivity as of full mesh. As Kumar mentioned is right spoke connectivity would go directly to london as a pass - through to other spoke

    It is OK if you have other PVCs; just do not use them on purpose of accidentally if you want to hub-spoke;

    often you get multiple DLCIs from ISP, choose right one for your goal;


    in fact, all rental-gear sites have full mesh so u can choose topology to use; full-, partial-mesh or hub-spoke, or hybrid;

    often, assigning unused DLCIs  to unused sub-interface is good pracitce in real life and on CCIE lab.
