Re: Reg: Inter Area routes into non-back bone areas in OSPFv3
[In reply to]

Thanks for the Reply AI,
I dont thing quagga has implemented RFC 3509.
I have fixed quagga ospf6d from sending the INTER Area routes from non back
bone areas into other non -backbone areas.
ospf6_abr.c (quagga version : 0.99.20)
============================
266a267,278

!IS_AREA_BACKBONE(area))

Can anyone let me know if this is fine.
How can I make quagga ignore the received inter area routes from non-back
bone areas.

Narender
