There are some options here. My current thought is use IGP to the maximum
extent (so I can blame the IGP:-). All packet forwarding is using FIB
lookup. 1st on DA, if no_match on BR address. I'm not sure yet on what a BR
should inject in the IGP, the full prefix it owns or just its configured
prefix on an interface. I'll write the options down in the I-D on BRDP Based
Routing (give me to the end this week).
The BRDP metric (UPM) is related to metrics of IGP, but not one to one. UPM
is for both directions and would be "uniform" for different IGPs.

I think it is always a compromise. Using ND is neutral on IGPs. And IPv6
routers have ND functions. 
Hosts may use BRIOs, ND is preferred over IGP for this reason.

Teco.
