ospfv3 summary route

Ospfv3 summary question please.

Rack1R2(config-rtr)#do sh run | be ipv6 router ospf 1

ipv6 router ospf 1

log-adjacency-changes

Rack1R2(config-rtr)#do sh ipv6 rou ospf

IPv6 Routing Table - default - 7 entries

Codes: C - Connected, L - Local, S - Static, U - Per-user Static route

       B - BGP, R - RIP, I1 - ISIS L1, I2 - ISIS L2

       IA - ISIS interarea, IS - ISIS summary, D - EIGRP, EX - EIGRP
external

       O - OSPF Intra, OI - OSPF Inter, OE1 - OSPF ext 1, OE2 - OSPF ext 2

       ON1 - OSPF NSSA ext 1, ON2 - OSPF NSSA ext 2

O 2001:150:1:5::5/128 [110/1]

     via FE80::201:64FF:FEAF:D01C, GigabitEthernet0/1

OE2 2001:150:1:10::/64 [110/20]

     via FE80::201:64FF:FEAF:D01C, GigabitEthernet0/1

in R2's route table (above) you can see I have.

2001:150:1:5::5/128

2001:150:1:10::/64

A v6 router further away sees these from r2 as.

Rack1R1#sh ipv ro ospf

IPv6 Routing Table - 8 entries

Codes: C - Connected, L - Local, S - Static, R - RIP, B - BGP

       U - Per-user Static route

       I1 - ISIS L1, I2 - ISIS L2, IA - ISIS interarea, IS - ISIS summary

       O - OSPF intra, OI - OSPF inter, OE1 - OSPF ext 1, OE2 - OSPF ext 2

       ON1 - OSPF NSSA ext 1, ON2 - OSPF NSSA ext 2

O 2001:141:1:12::2/128 [110/2]

     via FE80::201:64FF:FEDE:D81B, Serial2/0.1

OI 2001:141:1:25::/64 [110/3]

     via FE80::201:64FF:FEDE:D81B, Serial2/0.1

OI 2001:150:1:5::5/128 [110/3]

     via FE80::201:64FF:FEDE:D81B, Serial2/0.1

OE2 2001:150:1:10::/64 [110/20]

     via FE80::201:64FF:FEDE:D81B, Serial2/0.1

wanting to summarize these into a single route at r2 such that r1 only sees
one route I try.

Rack1R2(config-rtr)#area 1 range 2001:150:1::/48

And then at r1 I see.

Rack1R1#sh ipv ro ospf

IPv6 Routing Table - 8 entries

Codes: C - Connected, L - Local, S - Static, R - RIP, B - BGP

       U - Per-user Static route

       I1 - ISIS L1, I2 - ISIS L2, IA - ISIS interarea, IS - ISIS summary

       O - OSPF intra, OI - OSPF inter, OE1 - OSPF ext 1, OE2 - OSPF ext 2

       ON1 - OSPF NSSA ext 1, ON2 - OSPF NSSA ext 2

O 2001:141:1:12::2/128 [110/2]

     via FE80::201:64FF:FEDE:D81B, Serial2/0.1

OI 2001:141:1:25::/64 [110/3]

     via FE80::201:64FF:FEDE:D81B, Serial2/0.1

OI 2001:150:1::/48 [110/3]

     via FE80::201:64FF:FEDE:D81B, Serial2/0.1

OE2 2001:150:1:10::/64 [110/20]

     via FE80::201:64FF:FEDE:D81B, Serial2/0.1

is there a reason why I don't see the /64 being removed from the
advertisement from r2 to r1 ? does it have something to do with the OI and
OE2 difference between the 2 prefixes that is disallowing r2 to include them
as a single summary ?
