[mpls-linux-general] problem witth testing mpls and MTU=0

[lili l. <lit...@gm...>]

Hi,

I need help for my linux-mpls tesbed.
I success to configure my testbed like the one in "sourceforge - example"
But if I test with a ping command, it does not work.
In addition I have the following output after executing  "*mpls nhlfe add
key 0 instructions push gen 1000 nexthop eth2 ipv4 .... *"
*
NHLFE entry key 0x00000002 mtu 0 propagate_ttl
     (0 bytes, 0 pkts)*

Is it normal to have MTU=0?

Thanks for helping me.
