Re: [mpls-linux-general] the question about the mplsd fail :(

[Folke A. <aeo...@ho...>]

no, i haven't do a test on OSPF network yet.
and recently i am busy , and i'm sure whether i
can find some time to do this in the recent
weeks :(

i attached my qdisc_cfg file.
i first run
  $iptables -A OUTPUT -t mangle -j FTOS --set-ftos 0xfc
this will mark the packet origined from the local machine
be marked with a dscp=0x3f, which in my qdisc_cfg file
has the highest priority.
  then , i run
  $qdisc_cfg core
which will first setup a prio qdisc with 5 bands,
band 4 is used for the packets with a dscp=0,
and band 2 is used for the packets with some none zero dscp value

band 0, band 1 and band 3 are currently not used.

i can say that after i do the following two steps ,
the packets from local stack is always have
a dscp value 0x3f, which will be send out first.
of course the traffic generated by the tcpblast
is marked with a zero dscp value.

i also noticed that, no matter i use qdisc_cfg or
not, the results are the same -- the ldp stopped
after about 10 to 15 seconds of the congestion. :(

folke.
