[mpls-linux-general] RE:mpls-linux-general] MPLS over ATM (2684bridgedPVC)

[Sanchez, F. (Fernando) <fsa...@lu...>]

Hi Vivek,
what do you mean with using 2684 (former 1483) for encapsulating MPLS into
ATM? wouldn't it make more sense to use either ATM as the MPLS layer 2 (thus
doing Cell mode MPLS operation with ATM label switching), what I think would
be outside the scope of the list as there is no linux driver for mpls on ATM
NICs; or running frame mode MPLS and shim header in the Ethernet NIC with no
ATM at all ...

I just can't see the sense in encapsulating IP/MPLS/PPP/ATM all over
again... If the scenario is that the box doing the MPLS processing is in a
LAN that is going to the world outside through an ATM switch/router,
wouldn't it make more sense that the ATM box is the LER, and the box with
the ethernet NIC do just IP/Ethernet ? please correct me if I am wrong

thanks, best regards
	Fernando

Hi ,

I am new to MPLS and am planning to use the 2684bridged encapsulation to
create interfaces for running mpls over atm.
The example suggests using `atmarp` from the clip package to create the
interface, but is it possible to use the atm interface created by 2684
bridgedPVC patch for atm for MPLS.
Reason being with `atmarp` we can only create one IP interface (i.e.
"atm<no.>") where the "no." depends on itf number of the NIC.
Please correct me if i am wrong.

Thanks in advance.
