I have set up OpenBSD on all of the routers instead of just the PE3 router. While all of the pseudowires get created properly and the interfaces are properly discovered, running ldpctl show lib shows that not all remote labels have been created. Any hints would be appreciated.

Hello.

I have created a setup like the one described here, but with all nodes based on OpenBSD 5.9, but I think there is a problem with the MTU definitions. When sending a packet from CE1 to CE2 or CE3, all works well except for packets near the maximum MTU (1500). With the configuration shown here, sending a ping with data size 1474 from CE1 to CE2, PE1 crashes (kernel panic). The message is "panic: kernel diagnostic assetion "ifp != NULL" failed: file "../../../../net/if_mpw.c", line 368. I have tried both OpenBSD 5.9 and OpenBSD 5.8, the only difference being that in 5.8 the assertion failed is in line 372 of the same file if_mpw.c.

It is a problem in the MTU size of the pseudowire interfaces and the underlying interfaces emX. Increasing their MTU solves the problem. Anyway, is there a way for not crashing the system when the MTUs have the default values?
Thank you for any help.
