I have these loopback interfaces:
lo4 2004::4:1/112
lo5 2004::5:1/112
lo6 2004::6:1/112
lo7 2004::7:1/112
I want to summarize them at the area boundary, using "area range" command. I get the following error:
R1(config)#ipv6 router ospf 6
R1(config-rtr)#area 12 range 2004::4::/110
^
% Invalid input detected at '^' marker.
R1(config-rtr)#area 12 range 2004::4::?
X:X:X:X::X/<0-128>
R1(config-rtr)#area 12 range 2004::4/110

Hi,
area 12 range 2004::4/110
the prefix should be 2004::4:0/110 and are you sure the prefixes you want to summarize are in the area 12
Regards.

Hi Alain,
Router R2 is connected to R1 through a frame-relay circuit. R2 is ABR. R1 is internal router in area 12.
R2 does not see the summary route. Instead, it sees individual routes:
R2#sh ipv6 route
IPv6 Routing Table - 11 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

Hi,
R2 is ABR. R1 is internal router in area 12.
you can summarize in OSPF on 2 locations only: ABR or ASBR so summarizing on R1 will have no effect.
So you must summarize on R2 and on an intenal router in area 0 you should see the summary route( OI route).
Regards.
Alain.
