We currently have a router with an
ATM connection from our service provider. This ATM interface on the router has sub-interfaces that are point-to-point with different DLCIs and are used to reach external sites. I need to move those connections to a different router that already has an existing IMA connection from the same service provider. The IMA interface also has point-to-point subinterfaces each with its own DLCI. If I reuse the DLCI numbers from the ATM subinterfaces on the first router, can I just configure them on the new IMA router? Do I need to involve the service provider to re-map anything? Would the external sites need to change anything in their router configs if I reuse the same DLCIs? Thanks for all your help.
