[mpls-linux-general] Mpls traffic ??

[Javier S. L. <sj...@te...>]

Hi all,

im making some test with 2 pcs acting as lsr, and with mpls support
enabled, and all the tools compiled and working (mplsadm - ldp_linux).

I set up 1 label in each computer, and add the IN entry on both with
each label , i mena:

LSR1 - 192.168.0.4

mplsadm -d
mplsadm -A -B -O gen:2614:eth0:ipv4:192.168.0.5 -f 192.168.0.5
mplsadm -A -I gen:1234:0
mplsadm -L eth0:0


LSR2 - 192.168.0.5

mplsadm -d
mplsadm -A -B -O gen:1234:eth0:ipv4:192.168.0.4 -f 192.168.0.4
mplsadm -A -I gen:2614:0
mplsadm -L eth0:0


Then i started ethereal, and make some ftps and ping to generate some
traffic but ethereal shows no mpls traffic. i see normal tcp traffic,=20
acks , dns querys ... but no mpls packet ???

What am i doing wrong ?????


TIA for your attention

P.D. The only messages on syslog are from LSR2, maybe somwone can see
here clues of wahts wrong, mpls wrote a lines there complaining about he
cant find FIB_NODE =BF?=BF?=BF?
