Dia and OSX Yosemite

For those of you whom are using this excellent opensource diagram software, since OS X Yosemite it seems it lacks one line to work correctly.
You must edit : ‘/Applications/Dia.app/Contents/Ressources/bin/dia’ and add at line 39 : “export DISPLAY=:O” such as :


[…]

 

fi
fi
export DISPLAY=:0
osascript -e ‘tell app “XQuartz” to launch’
for i in seq 1 30; do

[…]


 

Now it must work correctly :)

OSPF : Outbound filtering

If you read/see videos about OSPF, it will be said that you can only filter on INBOUND or 1/0 on OUTBOUND (via ip ospf database-filter all out / neighbor x.x.x.x database-filter all out).
You will say to me, no problem I can filter by means of “area range xxxxx not-advertise” (LSA Type 3) or “summary-address xxxx no-advertise” (LSA Type 5).
Ok, now let’s say, I want with distribute-list and ACL, you filter out some routes ?

You could do this as :

And you could do more :

Have lot of fun to lab all these great OSPF features.

Holidays

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)#router-id 10.1.9.9
R9(config-router-af)#redistribute connected
R9(config-router-af)#exit-a

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 10.1.6.6 on Serial3/0 from LOADING to FULL, Loading Done
R9(config-if)#ospfv3 1 ipv6 area 236
R9(config-if)#

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 :

It was mexican party with buritos and three milks cake…

For fun : HE IPv6 Sage certified :)

IPv6 Certification Badge for clucas

I am looking forward my Sage T-Shirt to travel through my home :)

To supply my lab studies…

I am doing lot of lab to study for my lab. This will help me. Welcome in my library little books :)
