I haven't dealt with multicast much, but I do know it is real picky
about what interface a packet appears to arrive on. With MPLS tunnels,
packets you receive off an LSP appear to come from the physical interface
(eth0 etc) I think pimd is expecting to see the packets come from the same
interface it sent them out (mpls0 etc). I think I added code at one point
to work around this.
mplsadm2 -L eth0:0
mplsadm2 -A -I gen:16:0
mplsadm2 -I gen:16:0 -i set:mpls0:pop:peek
I just looked at the code for mplsadm2 and it won't work without
some modifications, I'm attaching a patch against the latest version (1.935)
you can get the source for mplsadm2 at http://sf.net/projects/mpls-linux=20
Apply the patch by going into the mpls-linux/utils directory and execute
patch mplsadm.c < mplsadm.patch
then issue a 'make'
(make sure your system header files include mpls.h if not get
my glibc-headers RPM from http://sf.net/projects/mpls-linux)
