[Xorp-users] simple xorp configuration

[Bruce Simpson]

Hi,

    Sorry for the delay in responding to your question. As you can 
probably tell, the project is in a state of change at the moment, this 
is going to affect community support for some time.

    I haven't been directly involved in the vlan code, perhaps someone 
else on the list is more familiar with this than I am, so I am afraid I 
can only offer very general pointers, as I'm currently tied up elsewhere.

    Did you look at fea/iftree.cc line 1607? This assertion looks as 
though it's being triggered because you have more than one interface 
with the same interface index in this system. XORP's FEA will use the 
interface index as the primary key for learning about network interfaces 
in the system.

I took a quick look on bugzilla.xorp.org and couldn't see anything about 
this, so I'm assuming it isn't a bug, for now.

Have you tried creating the VLAN interface from outside of XORP? Do you 
see similar errors?

This sounds similar to stuff other folk ran into, and the workaround was 
simple, off the top of my head, try the list archives.

cheers,
