Re: [mpls-linux-general] packets not delivered to layer 3 (??)

Hi James,
I tried executing the command in two steps. But no
luck! This is what I get...

#mplsadm2 -A -O 0
Key: x00000000    (all zeroes!!)
Out Segment add: Success

But it adds an entry to /cat/proc/mpls_out i.e.
0x00000007 0/0/0 1

Then,
#mplsadm2 -O 0x00000007 -o
push:gen:100:set:eth0:ipv4:10.3.8.198
Out Instr: Success

But the entry in /cat/proc/mpls_out remains
0x00000007 0/0/0 1

So, the two step process didn't work. But, could you
explain, why is this happening only on machine B?! Set
up of LSP works fine on machine A. Moreover the
addition of incoming label on machine B works fine
too. Only the addition of outgoing label on machine B
causes problem!
Strange!

Again, thanking in anticipation! :-)
cheers,
Sameer
