Re: [ns] RE: MPLS simulation with NS/2

Hi Munaf,

I don't know your exact problem, but maybe this helps a bit.

With MNS version 2 (MPLS extension for ns-2.1b6) you can set up ER-LSP's:
$node setup-erlsp $FEC $route $LSPID

You can bind flows to such a ER-LSP:
$node bind-flow-erlsp $FEC $fid $LSPID

Further you can assign a flow id to a source:
$source set fid_ $fid

Now if you reserve 1 flow id "a" for a VPN "a", then only sources of flow id
"a" may use the LSPs you created: like a VPN.

What you maybe also want to do is reserve resources on the LSP's of a VPN.
This can be done by setting up CR-LSP's instead of ER-LSP's.

Success!

Onno
