Solved: Can Not Create T3 Multilink on 7613

davidhuynh5 · ‎12-10-2009

I currently have two T3 multilinked on 7206vxr and need to move this multilink over to a new chasis (Cisco 7613, IOS 12.2(33) SRC4).

When I try to create the multilink on the 7613 it does not work. I'ev created multilinks before and have never had any issues. Attached is the show tech. Does anyone know why it doesn't work? Any assistance would be greatly appreicated.

Hello David,

>> just so that I understand you correctly. I will have to break the bundle and create seperate /30 connections for each WAN link?

yes this is your only option

Hope to help

Hello David,

you have

5 0 2 port adapter Enhanced FlexWAN WS-X6582-2PA

see restrictions for distributed multilink in flexwan configuration guide

Distributed MLPPP is supported only for member links configured at T1/E1 or subrate T1/E1 speeds. Channelized STM-1/T3/T1 interfaces also support dMLPPP at T1/E1 or subrate T1/E1 speeds. Distributed MLPPP is not supported for member links configured at clear-channel T3/E3 or higher interface speeds.

you need to move to two or three parallel L3 links

Hope to help
