I got the problem, hate it when this happens! I send a mail to
groupstudy and 5 mins later I figure out my brain had stopped working.
:-(
The prefix list is wrong. It should be
ipv6 prefix-list ROHAN seq 5 deny 3001:5::/64
ipv6 prefix-list ROHAN seq 10 permit ::/0 le 128
On a related note...since in IPv6 routing protocols are configured
directly under interfaces, the concept of passive interfaces no longer
exists right?
So if I want to advertise a loopback ipv6 int in RIPv6, I would
configure 'ipv6 router rip <name>' under Loopback and things work great,
but then rip updates will be sent out on L0 going to Null..this is not
really desirable right? Anything to prevent this?
Thanks
Rohan

Subject: IPv6 Rip Distribute list
Hi,
I have configured IPv6 RIP on 2 routers R1 and R2. I now want to filter
a certain prefix 3001:5::/64 and permit all others on R2.
To do this I created a ipv6 prefix list on R2
ipv6 prefix-list ROHAN seq 5 deny 3001:5::/64
ipv6 prefix-list ROHAN seq 10 permit ::/0
I applied this list to the ipv6 router rip
ipv6 router rip RIPA
distribute-list prefix-list ROHAN in
But I see that only a default route ::/0 sent by R1 is being installed
in the R2 ipv6 routing table. Other prefixes being advertised by R1 like
2001:1::/64, 2001:2::/64 are all being rejected by the filer as per the
debugs
00:35:14: RIPng: Input filter rejects 2001:1::/64
00:35:14: RIPng: Input filter rejects 2001:2::/64
Why is this happening? Is there a different logic to be used for
distribute list filtering for ipv6?
Any help will be much appreciated.
Thanks
Rohan
