PPP Interface down

[Anonymous]

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
