Re: [mpls-linux-general] MPLS FEC port

[Adrian P. <adr...@gm...>]

Hello,

To classify packets based on something else than destination IP (like your
case), you need to use iptables/ebtables. So, instead of:
ip route add 129.175.237.24 via 129.175.237.21 mpls $var
you would need to add a iptables rule that uses the $var. Look for examples
in the QoS experiments (e-LSP and l-LSP) for iptables syntax (the matching
there is done based on DSCP, but you can easily match ports instead).

Good luck!
Adrian
