    PPP Interface down

    knevyn New Member

      Router is 3200

      AOS 10.6

      No shutdown has been applied to the PPP interface.

      T1 Interfaces are up

      Any suggestions on what to check next?

          You have two T1 interfaces connected but the ppp interface is configured with no multilink .


          Try:


          config t

          interface ppp 1

            ppp multilink

          end

          wr mem

              jayh's solution should work if the rest of the configuration is correct.

               

              If you still have issues, check the show run for the T1 and cross-connect configuration.

               

              This works for a 3450 with 2 T1 cards:

               

              interface t1 1/1

                tdm-group 1 timeslots 1-24 speed 64

                no shutdown

              interface t1 2/1

                tdm-group 2 timeslots 1-24 speed 64

                no shutdown

              interface ppp 1

                ppp multilink

                cross-connect 1 t1 1/1 1 ppp 1

                cross-connect 2 t1 2/1 2 ppp 1

                ppp multilink interleave (optional)

                no shutdown

              end

              wr mem
