ipv6 prefix-length filter for ipv4 prefix-length 32 eg the router discards as if it were a 32 ipv6 prefix since it did not distinguish the prefix-length v6 from v4 with that which has filter summarization when summarizes in ospf the pppoe routes / 32 it also discards every ipv6 block 32
On routing filters, use Address Family option (IP or IPv6) to apply that filter to only one type of address, so you dont catch v4 and v6 together.
in fact I already do what your friend recommended in the bgp section, these filters I quoted are ospf-in and ospf-out which are used for route summarization / 32 of ipv4 pppoe. I do not know if I’m doing something else wrong in order when I activate ipv6 it does not work if I do not get my route summarization filter out. OBS. the filter made on the ospfv4 tab and the bgp filters tab. because neighbors ospf close section with the bgp router so it has ospf in both the neighbors and the edge
