This seems to be the way it is.
But while we're on it: I use ATM subinterfaces, with "pvc" style syntax:
interface ATM2/0.32 point-to-point
bandwidth 2000000
ip unnumbered Loopback0
pvc sp1 15/32
ubr 2000
oam-pvc manage
encapsulation aal5mux ip
and nearly everything works nicely, that is:
- everything in order -> line is "up/up".
- line is broken, remote end disconnected -> OAM fails -> line is "down/down"
what I would like to see is:
- line is looped back -> OAM detects loop -> line is "up/up (looped)"
but that doesn't happen right now, the loopback condition is not
recognized and the Interface just stays "up/up", which is bad for
dial-backup etc.
Does this ring a bell for anyone? Is there a workaround, or is it
"bug your sales droid"...?
