Re: [mpls-linux-general] Binding to FEC.

[James R. L. <jl...@mi...>]

Sorry about that I gave you the wrong command line.

iptables -A OUTPUT -d 192.168.1.0/24 -j MPLS --set-key 0x2
          ^

Make sure you patched iptables, then do a full make install.
iptables must be run as root (it needs to load dynamic libraries which 
are places in your hosts files system via 'make install')

-A OUTPUT adds this rule to the OUTPUT netfilter.
--set-key <key> is what bind the packet going to the destination to
the outgoing label.  In the above example 0x2 is the key (found by looking
in /proc/net/mpls_output) for the outgoing label you want to use.

I hope this helps.

PS There is one other person who is using the diffserv instructions.
If you would like I could include him in the e-mails and he might be
able to help out.  Also, he has been finding lots of bugs, so make sure to
ask when things that 'should' work, aren't.
