Re: [mpls-linux-general] Ping in MPLS

Sorry for the delay.

To implment LSP ping, you will need to finish the MPLS socket implementation
then implement a userland daemon that listens on UDP port 3503
(MPLS echo requests port).  The MPLS socket code will allow a userland
aplications to construct the LSP ping request packet then choose which
NHLFE it wishes to send the packet on.  You will need to create a
sockaddr_mpls which contains the NHLFE key.  (you might also want to think
about how an application would register an ILM that is bound to a socket, also
there is a router alert label which needs to forward the packet on a socket
as well) Then fill in all of the socket functions needed to
create/bind/connect/listen/send/recv on the MPLS socket. The framework is
already there in net/mpls/af_mpls.c

Let me know if you need more info.
