I have all sorts of options on my IOS....

What version (specifically) are you running?  Give output from 'show
version' and that may assist some.

Forgot to mention that with the config below, once I had it running on
remote side and entered the ppp multilink command on the HQ serial
interface, link goes down and could not be established. If I removed ppp
multilink on HQ serial interface link was re-established immediately.

I checked on CCO and saw a bug that says MLPP bringing causes IPCP to
close for some IOS versions. Since configuration method I was using was
a bit new to me, I was not sure if it was bug or my misconfiguration

Regards,

Bola

Yeah I have ability to that. I did use the it

Doing sometime like this

Interface Virtual-template 1
encap ppp
ppp multilink
ppp multilink interleave
ppp multilink fragement-delay 8
!
!
Multilink virtual-template 1
!
!
Int s0/0
ip add 
encap ppp
ppp multilink


may be I was lost on how to bind virtual-interface to serila interface,
what should I have done? I checked but I could find nothing like a
"multilink-group number" on serial interface.

Tanx!

By the way, instead of 'interface multilink 1', do you have the ability
to do 'interface virtual-template 1'???  That may be the method for your
IOS version.

I figured out what RAN is, but I'm not sure what the 64/25 refers to.
What is the bandwidth of this radio network?  If it's approaching T1
speed or above it, serialization delay shouldn't affect the voice
quality.  Voice is fine up to about 100 ms delay.  What kind of traffic
is on the line?  What IOS are you running?  With the right version, you
could use NBAR to monitor and/or rate limit to a pretty high detail.
When you say it's clear at times, and choppy at other times, what
activities are occurring on the network when it gets choppy?  IP
accounting may be of use also.  HTH.

Hi all,

I have a situation with two routers (2611 running ) connected via a
wireless link using RAN 64/25. voice network is connected via E&M ports
with Avaya definity on one end and Alcatel on the other side.

All is set up but I have QOS issues on line. Due to IOS limitations I
can only do custom-queueing/priority queueing

Presently I am using ip rtp rpiority.
1 The line is quite clear atimes and atimes it breaks. My suspicion is
that serialization delay causes this inspite of Ip rtp priority

I wanted to use a multilink interface to set ppp LFI and fragmentation
delay but IOS does not support multilink interfaces (i.e interface
multilink1)

I am looking at way for doing LFI so that serialization delay is withing
acceptable but I have looked at the options are I can thik of can't see
any that satisfies. Pls any ideas?

also due to congestion issues ring back is not heard atimes and caller
just hears called party saying hello. This I believe is due to TCP call
setup and tear down channels going within normal queue. I was wondering
if it was possible for me to have priority queueing on same interface as
ip rtp priority. reason I am thinking of this is so that I can put only
the setup channel within this queue so that users hear the call alerts
whatever congestion situation is.

Pls any bright ideas to help me out.
