Hi All,
I have a doubt in DR and BDR process in OSPFV3.
“ *AllDRouters*:
This multicast address has been assigned the value
FF02::6.
*Both the Designated Router and Backup Designated Router must be*
* prepared to receive packets* destined to this address. Certain
OSPF protocol packets are sent to this address during the
flooding procedure.”
RFC says, DR & BDR must be *prepared* to receive packets destined to
FF02::6, Here is that *Prepared* means to say BDR needs
to process the packet with destination address FF02::6 (ALLDRouters)?
In CISCO routers, BDR is not processing the packet with destination address
“ALLDRouters”.
But the same BDR when it receives an update packet with destination address
as “ALLSPFRouters”, it is processing the packet.
So I want a clarification of the above lines in the standard.
