During these holidays on this beginning of may has been used for work at home and in our garden. Nevertheless, some work has been done on OSPF during these last two weeks. CCIE studies has been indeed slower than in April. It will be at 100% in beginning of the next week.

Some fun on this off-day.

I have found again this networking game. The first time I play with it was in 2009. It was fun to take some hours to play with it.
It is not hosted by Cisco, so if you want to retrieve the archive you can download it here for those of you that were not in this industry or not know this cisco networking game.

OSPFv3 address-family

This is possible to run the two address-families under the same OSPF process since Cisco IOS Software Release 15.1(3)S.

You can do this as :
R9(config)# ipv6 unicast-routing
R9(config)# ipv6 cef

Then :

R9(config)# router ospfv3 1
R9(config-router)#address-family ipv4 unicast
R9(config-router-af)#redistribute connected

And then configure the OSPF link by means of configuration on the interface :
R9(config-router-af)#int ser 3/0
R9(config-if)#ospfv3 1 ipv4 area 236
*May 13 20:31:14.956: %OSPFv3-5-ADJCHG: Process 1, IPv4, Nbr on Serial3/0 from LOADING to FULL, Loading Done
R9(config-if)#ospfv3 1 ipv6 area 236

This is where I think it is really powerful.
I recommend you to check IPv6 and OSPF only with the keyword “ospfv3″ such as :

On R6 we can see now :
