[mpls-linux-general] I have a problem setting up the MPLS for Linux example: MTU=65535

[<ja...@in...>]

Dear subscribers,

I have a problem setting up the first IPv4 over MPLS example.

the command:
"mpls nhlfe add key 0 instructions push gen 1000 nexthop eth2 ipv4 ...."

gives the output:
"NHLFE entry key 0x00000002 mtu 65535 propagate_ttl
    (0 bytes, 0 pkts)*"    ^^^^^^^^^^^^^^


Information about the components:
--------------------------------

1. mpls-linux version: 1.971

2. patched linux-source: linux-source-2.6.32, 2.6.32-34squeeze1
dmesg | grep MPLS
MPLS: version 1.971
MPLS: protocol driver interface - <jl...@mi...>
MPLS: IPv4 over MPLS support

3. iproute and iptables from:
http://www.inf.ufrgs.br/~rwestphal/mpls-linux/debian/lenny/
iproute version: 1.4.8-3
iptables version: 2.6.35-1

4. Linux runs in a Virtual Machine from VmWare.


Effect
------

After the next command from the example:
"ip route add 10.0.0.2/32 via 172.16.0.3 mpls 0x2"

the load of the cpu goes up to 100% and Linux isnt responding anymore.


Perhaps someone has an idea how to solve this.


with best regards,
Jan
