[FROG] Link Scope IPs

[Chris Malton (Delta V)]

Hi all,

I'm sure this must have been asked before, but is it possible to set 
"scope link" on an IP address in FRR?  I use private link addresses 
heavily because of the exhaustion of v4, and therefore everything is 
using RFC1918 internally.

While I'm deploying v6 and we don't have issues there, I don't want 
RFC1918 addresses to show up (or, indeed, fail to show up) for v4 
traceroutes.  All of my routers have loopback addresses, and I'd like 
Linux to use them in preference to the RFC1918s on the interface.  The 
normal way of me doing this is to set "scope link" on all of them.

Alas, such an option doesn't seem to exist in FRR.

Am I missing something?

Regards,

Chris Malton
