OSFPV3 summarisation

[christianpho]

Hi,

I'm actually using CML for studdie for my CCNP recertification.

I had created an OSPFv3 environment using IOSv 11 routers with 5 areas.  In the area 4 I have 1 one router other than the ABR on which I created some prefixe to summarise.

On the ABR I was expecting to be able to summarize them.  Using the area 4 range command under the OSPFv3 routing process but the area range is not available ?

Where I should configure the summary ?

According to this post, I understand that for IPv6 Iit is under the routing process configuration that I need to confirgure summarization.

Both for some reason this router plate-form in CML do not allowing it...

Thank you,

Hi @christianpho ,

ospfv3 supports multiple address families. You need to go under the address-family section to enable summarization.

R1(config-router)#router ospfv3 1
R1(config-router)#address-family ipv6 uni
R1(config-router-af)#area 4 ?
authentication Enable authentication
default-cost Set the summary default-cost of a NSSA/stub area
filter-list Filter networks between OSPFv3 areas
normal Specify a normal area type
nssa Specify a NSSA area
range Summarize routes matching address/mask (border routers only)
stub Specify a stub area
virtual-link Define a virtual link and its parameters
