Renaming the interfaces internally by XORP is one possibility.
The reason we currently chose to keep same name inside the XORP
configuration and what you see by "ifconfig" is to make it easier to
the user in case they want to match the XORP configuration with the
system's view of the interface names. Otherwise we have to provide
somewhere a map between those names which makes things more
complicated.

As I mentioned in my earlier email I was looking exactly into the
VLAN-related ioctl() API, but I couldn't see any indication that you
could use that particular API to change the VLAN name.
Could you provide me with an example of how to do that.

I wasn't aware of the effort to add VLAN support to Netlink. I was
looking into the iproute source code but I didn't see any reference.
Please let us know when the Netlink support is available, and we
will try to add Netlink-based VLAN plugin at the bottom of the FEA.

Thanks,
Pavlin
