3 FR Link with Single DLCI Number

Unanswered Question
Aug 26th, 2009

Hi All,

Our service provider gives us 3 separate E1's. They told us to configure our router's sub serial interfaces and give us only 1 dlci number. Is this the right way of doing this? Only one dlci for the 3 separated E1 links?

Im aware of the multiple dlci's on one interface but this one, im a little bit confused.

I will much appreciate any of your help guys....

Thanks in advance cisco guru's! More power to cisco world.

I have this problem too.

Hi Chester,

How are these three E1 lines terminated on your router? Is each of them terminated on a separate physical interface? If yes then a single DLCI will work just fine because each interface maintains its own table of DLCIs and mappings so there is no ambiguosity.

Best regards,

Peter
