[mpls-linux-general] Is possible to strip-on labels on traffic incoming/outgoing to/from specific port ?

[Rodzina A. <rod...@ga...>]

Hello,

I was looking in achival postings and documentation and I could not find
answer for my question. Is possible to use mpls to put labels on packets
outgoing from specific ports ?

If I make commands:

#mpls nhlfe add key 0
#mpls nhlfe change key 0x02 instructions push gen 90115 nexthop eth0
ipv4 117.102.93.81
#ip route add 117.102.93.81/32 via 117.102.93.81 spec_nh 0x8847 0x2

then all packets going to 117.102.93.81 will have label 90115.

But what if there are multiple services with different output ports and 
there is a need only to label outgoing packets from one certain service?
For example SSH @ port 22 of FTP @ port 20 ?

And similar question about incoming traffic.
Is possible to strip-off labels from packets incoming to specific port?
For example Samba @ port 612 ?

And one more thing.
Is hrere anyone who succesfully installed zebra-0.94-1+ldp0.310.i386.rpm
and quagga-0.97.3-1.FC3mpls1_946a.i386.rpm on OS with
libreadline.so.4.3 ?

I have libreadline.so.4.3 and I got errors:
rpm -iv zebra-0.94-1+ldp0.310.i386.rpm
error: Failed dependencies:
        libreadline.so.4 is needed by zebra-0.94-1+ldp0.310

rpm -iv quagga-0.97.3-1.FC3mpls1_946a.i386.rpm
error: Failed dependencies:
        libreadline.so.4 is needed by quagga-0.97.3-1.FC3mpls1_946a


Whjat is wrong?
Do I have to install older version of libreadline.so ?

Thank U for help in advance.
