[mpls-linux-general] How can I know MPLS work?

[yu-xiao j. <yx...@ho...>]

Hi James,

I have setup a small MPLS domain in our lab for testing the implementation 
using your mpls-linux.
            /---LSR1---\
Host1--- LER1           LER2 --- Host2
            \---LSR2---/

I have two question:
1. Since Tcpdump and Ethereal can not see the label, How can I know the 
packet forward is based on IP or MPLS. I mean how can I know whether MPLS 
work or not even though I setup the label using mplsadm in each router.
2.When I setup a mpls testbed. it is a small LAN. In each router I confige 
static routing table to make sure each node can ping each other in this 
local network. Then when I use mplsadm, Do I need to add "route add......" 
command? In the future, I need to use ldp-portable to dynamic setup the 
path. So question is " IP can have static and dynamin routing table, MPLS 
can static or dynamic setup the path, which is the best way to test the mpls 
implementation?"

thanks in advance,
looking forward to you reply,


Jenny (yuxiao)
