Command to Display Prefixes and Default router entries in Linux

[Dheeraj Kandula]

Hi All,
     In FreeBSD we have the "ndp -p" and "ndp -r" to display the Prefixes
and the default router entries learned from Router Advertisements.

Is there an equivalent command in Linux?

I tried "ip neighbor" but that doesn't display the entries related to RA.
