Hi guys,
im still finding some documents here related to MLP on atm interfaces. Most of the documents i found are more on serial interfaces. Will this work.
thanks.

Dear Jeff,
Kindly find the below MLP ATM configurations example, i hope that help you

Hi Mounir,
would i still configure multilink interface on these one ? another thing is im using BGP on these will this affect my config ?
thanks.

Dear Jeef,
There are no problem problem to use BGP through all the links as soon as the links provided by the same provider and you are establishing the session via loopback ip address.
Jeef your case not clear please provide me with the senario that you would like to use to provide you with optimum configurations that can reach you needs.

Hi Mounir,
Before we are using two isp to multihome. Now we had to remove one to cut cost and the other one told us to have a redundancy thru physical link. Its like having 2 fiber links with different geographical path. If one of the two fiber that would be damage, still we'll have connectivity. Here's the setup as per our isp.
1. Multilink via atm.
2. Single Local Router connected to their single router
3. 2 atm interfaces configured multilink for failover
atm1/0 ----fiber--- atm interface
R1 ---- --- ISP Router
at2/0 ----fiber--- atm interface
Here's basically the setup. Its for failover using MLP via atm.
Thanks.

Dear Jeff,
I hope to solve your problem this time :)
I got that you have one router with 2 ATM controllers and each controller facing provider router or even interface and and you gone bundle both ATM interfaces by MLPPP, and using BGP over the MLPPP interface Right? So you can use MLPPP via virtual-templete or via MLLP interface
Example 1 - (ATM Router) Virtual-temp interface
interface Loopback1
ip address 1.1.1.1 255.255.255.252
!

interface Virtual-Template1
bandwidth ???
ip unnumbered Loopback1
ppp multilink
ppp multilink fragment delay 14
ppp multilink interleave

Hi Mounir,
Thanks, lots of info i got from your config. I was thinkin why multilink and virtual template was provided by my isp. Here's the initial config, please comment on these. And kindly explain some of the commands involve, still finding some sites for these kind of setup.

Hi Mounir,
I would like to ask if where should i implement my acl, is it on the atm interface or on the multilink interface ?
Thanks.
