[Ethereal-users] Ethereal and L2 MPLS

[hari <rhariharan@xxxxxxxxx>]

Hi,

Can ethereal properly identify L2 MPLS pkts?

The pkt format I am trying to create is like this:

OuterL2|OuterMPLS<32bits>|InnerMPLS<32bits>|ControlWord<32bits>|InnerL2|L3|L4...

Ethereal does not recognize this and interprets data from ControlWord onwards wrongly.
I am setting the controlword = 1 in N/W byte order. I also tried to set it to 0.

However if i remove the ControlWord, and have a pkt like this, ethereal shows the data correctly.

OuterL2|OuterMPLS<32bits>|InnerMPLS<32bits>|InnerL2|L3|L4...

Basically I need to know if my interpretation of L2 mpls with ControlWord is correct as against ethereal's.

Thanks
hari
