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

Hi, can you send "show interface" and "show controller" for the three links comprising the bundle, taken on both routers.
