[mpls-linux-general] packets not delivered to layer 3 (??)

[<sam...@ya...>]

Hello James and all,

I have set up 1.152 on two Linux boxes running kernel
ver. 2.4.18-3. The two boxes are set up as...
 ---------             ---------
 |   A   |             |   B   |
 ---------             ---------
     |eth0                 |eth0
     |10.3.8.198           |10.3.8.93
-----------------------------------
         
And the lsp was created b/w A and B using...
On A :
mplsadm2 -A -O -o push:gen:200:set:eth0:ipv4:10.3.8.93
ip2 route add 10.3.8.93 dev eth0 lsp 0x00000002
mpls -L eth0:0

On B:
mplsadm2 -A -I gen:200:0
mpls -L eth0:0

I believe these commands are enough to create an LSP
between A & B... or at least I hope so.

Now, when I try to Ping B from A, the packets reach B,
but it seems the packets are not delivered correctly
up to layer 3 on B. The result is that the
acknowledgement doesn't reach back to A and A shows
100% packet loss. If I try to ping A from B, then the
ping packets reach A and come back to B (taking the
lsp from A to B). But again, the packets aren't
recognized by B and again ping shows 100% packet loss.
Similar thing happens when I tried injecting packets
using nemesis tools.

Is there any problem with the way I've set up the LSP
or is it some other problem?

Any help would be greatly appreciated.

Cheers,
Sameer
