Hi Stewart,

The ELI is a catch-all, in case there is any potential confusion that the EL may be interpreted as an app label.  Most app labels (PWs (via T-LDP or BGP), VPN labels, etc.) can easily be followed by an EL, as Shane's slides showed.  No need for new FECs.

The sticky case is "naked" IP over LDP tunnels.  Do you have a suggestion that doesn't need an ELI in that case?

Thanks,
Kireeti.
