Just like with IP prefix-lists, you need to look at what is being matched.
Without an "le" or "ge" addition, you are matching only those specific
routes.
So on your ::/0 route, you probably want to put "le 128" or whatever measure
you desire.
HTH,

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
