Hi,
I have configured a multilink (1 serial E1 links bundled to a single link) and after that i am facing some packet drops on that multinilk. During investigation i found some errors on multilink
------------------------------------
sh ppp multilink
Multilink2, bundle name is XXXX_Secondary
  Bundle up for 3w6d
  407491 lost fragments, 259087128 reordered, 0 unassigned
  494274 discarded, 439343 lost received, 28/255 load
  0xC50A00 received sequence, 0x25DB3B sent sequence
  Member links: 3 active, 0 inactive (max not set, min not set)
    Serial4/0/0, since 3w6d, last rcvd seq C50A03
    Serial5/1/3, since 3w6d, last rcvd seq C50A04
    Serial4/0/3, since 1d14h, last rcvd seq C50A02
---------------------------------------
See these lines
 407491 lost fragments, 259087128 reordered, 0 unassigned
  494274 discarded, 439343 lost received, 28/255 load
My multilink configuration  follows
interface Multilink1
 description ***** Connected to Dhondusa*****
 ip address x.x.x.x 255.255.255.252
 ip ospf cost 16
 no cdp enable
 ppp multilink
 ppp multilink fragment-delay 20
 ppp multilink interleave
 multilink-group 1
----------------------------------
I read somewhere that multilink interleaving is necessary only on low bandwidth links , so i removed 
 ppp multilink fragment-delay 20
 ppp multilink interleave
the above two commands from my configuration. But still... i am getting the same errors. I made sure that none of my physical  interfaces shows any errors or reliability isses..Can anyone pls help me to overcome this?
Thanks in Advance
Sony
