Acee:

Can you please get positive confirmation from the authors of
draft-ietf-lsr-dynamic-flooding?

Thanks!

Alvaro.

Right - the in-progress dynamic flooding implementations are IS-IS rather
than OSPF. I agree that moving the OSPF dynamic flooding is safter.

Thanks,

I doubt there is any OSPF implementation of
draft-ietf-lsr-dynamic-flooding, so it may be safer to use the
0x00000010 for draft-ietf-lsr-ospf-bfd-strict-mode and 0x00000020 for
draft-ietf-lsr-dynamic-flooding.

thanks,
Peter
