Have you tried to configure link fragmentation and interleaving for ATM using dialer interface?
As soon as I configure ppp multilink, connectivity is lost. Show interface shows multilink is open.
This is the doc with the configs:
Here is the config used:
r6
int dial 104
ip ad 69.69.40.6 255.255.255.0
en ppp
dialer pool 4
!
int atm 1/0.4069 po
pvc 69/400
encap aal5mux ppp dialer
dialer pool-member 4
r9
int dial 104
ip ad 69.69.40.9 255.255.255.0
en ppp
dialer pool 4
!
int atm 1/0.4069 po
pvc 69/400
encap aal5mux ppp dialer
dialer pool-member 4
Until this point, connectivity is fine. But adds fragmentation and interleave commands and it stop work:
ppp multilink
ppp multilink fragment-delay 8
ppp multilink interleave
I tried shut/no shut on atm, dialer, and reboot the router without success.
I checked the restrictions/prerequisites, but it seems to be fine:
===============================
Restrictions
The following restrictions apply to the LFI for Frame Relay and ATM VCs feature:
Only one link per MLP bundle is supported. If more than one link is used, there is no way of knowing which link is doing the LFI.
Only voice over IP is supported; voice over Frame Relay and voice over ATM are not supported.
Prerequisites
The following prerequisites apply to the LFI for Frame Relay and ATM VCs feature:
FRTS must be configured on Frame Relay interfaces.
Per-VC FIFO queueing must be configured on the Frame Relay and ATM VCs associated with MLP.
MLP over ATM must use the following ATM network modules:
Multiport T1/E1 ATM Network Module with Inverse Multiplexing over ATM
ATM OC-3 Network Module
Enhanced ATM Port Adapter
