Hi, I'm using dev tree (1.950) and trying to implement the simple Linux example. I have sync'd as of today (2005/12/07). I run into trouble in 2 places uml1: 'mpls nhlfe show' and uml2: 'mpls labelspace add dev eth0 labelspace 0' in both cases function never returns. Help please, -- -Bob |

Can you post the full set of mpls commands you issued? I cannot reproduce this on my machines.

Certainly,
after reboot, and kde startup, let's just start with uml1:
bash-3.00# cat /sys/mpls/version
1.950
bash-3.00# mpls nhlfe add key 0
NHLFE entry key 0x00000002 mtu 0 propagate_ttl
(0 bytes, 0 pkts)
bash-3.00# mpls nhlfe change key 0x2 instructions push gen 10000
nexthop eth0 ipv4 172.16.87.21
bash-3.00# /usr/sbin/ip route add 172.16.87.21/32 via 172.16.87.21 mpls 0x2
bash-3.00# /usr/sbin/ip route show
172.16.87.21 via 172.16.87.21 dev eth0 mpls 0x2
172.16.87.0/24 dev eth0 proto kernel scope link src 172.16.87.11
192.168.10.0/24 dev eth1 proto kernel scope link src 192.168.10.11
127.0.0.0/8 dev lo scope link
default via 192.168.10.7 dev eth1
bash-3.00# mpls nhlfe show
and it never returns, the console is not locked-up, just never returns with=
out
a ^C.
here is some other info:

So, I recompiled without SMP, (don't recall how that got turned
on actually), but it make no difference.

Any ideas?
If I run strace with the command I get this:

and it stops there. Does this shed any light?
on uml2: the very first command --
'mpls labelspace add dev eth0 labelspace 0'
hangs similar to 'mpls nhlfe show' on uml1.
If you have any suggestions about debugging this, I'll be happy
to try to help isolate the problem. Thanks,

After looking at the debug output over and over, I thought:
Maybe the command did what it is supposed to, but just doesn't
come back.
So, I went ahead and ^C'd after each mpls command which hangs,
and set up uml1 and uml2 as per the example, turned on
a tcpdump session on uml2, began pinging from uml1, and what
do you know! I can see MPLS wrapped pings!
Before mpls config'd on uml1: ping 172.16.87.15:

Hi all, I figure out that the latest version of quagga with mpls support in the Perforce repository is quagga-mpls / ldp-portable. Isn't it? Are you currently working on that (i see that the last changes were made on july)? I wonder if quagga-mpls is ready to be built with the latest kernel headers. Have you tried to build it lately?

I have a theory about it having something to do with SMP. Can your try compiling as a UP kernel and see if the problem persists?

Could you send me the kernel debug from running the labelspace command that hangs? Do you see this problem with 'mpls ilm show'? On Wed, Dec 07, 2005 at 10:25:09PM -0600, James R.

OK. I was able to duplicate your issue and I think I submitted a fix
for the add/delete/change/set commands not returnning. I still need
to figure out the show commands. Basically my tree was out of sync with the
repository, so you didn't have the same code as me.
Update you iproute-mpls tree and you will get my fix. One thing to note
is I changed the syntax of the labelspace command:
mpls labelspace set dev eth0 labelspace 0
^
|
no add or delete
To delete, set the
labelspace to -1

Here's a little diff for the mpls usage function:
bbeers@alakazam:~/download/perforce/p4client$ diff -uprN -X dontdiff
iproute2 iproute2-bb/
Binary files iproute2/mpls/mpls and iproute2-bb/mpls/mpls differ
diff -uprN -X dontdiff iproute2/mpls/mpls.c iproute2-bb/mpls/mpls.c
