multiple links between 2 nodes

[Athina Markopoulou <athinam@alohanet.com>]

Hello,

I have 2 nodes n1, n2. I would appreciate it if somebody could explain
me:  

1. if ns allow to have more than one SimpleLinks between them
2. Furthermore if it allows them to communicate through 2 diff. LANs.
like this:
n1-->LAN1-->n2 
n2-->LAN2-->n1

It seems to me that the Simulator variable
link_([$n1 id]:[$n2 id]) keeps only the last SimpleLink between 2 nodes.
So, in the case of 2 LANs, it will store the Link/LanDuplex between
n1,n2 created by the last LAN. Is that correct?

Thank you.
