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)#

For those of you who know the excellent web-iou, you will not be surprised that this new project from Andrea is really exciting and amazing.

To beeing keep updated : this new routers seems really well : IOS XE (IOSd over Linux, virtualization, …).

You can learn more about them on : http://lostintransit.se/2014/10/04/cisco-adds-new-routers-in-the-isr-4000-family/

Have fun to read this great article…

It is been a while that I read some papers about EVC, flexible matching, … But I have not found a good paper explaining EVC and a way to understanding well except to cisco configuration guide.

 

This figure is exactly what I searched for. This example is simple but enough to understand well how it works.

My misunderstanding was about “ingress” and “symmetric” : I didn’t understand, but now with the figure that it is clear that :

BFD is a mecanism which give you access to a fast switchover for IGP, EBGP, … It is a RFC protocol : RFC5880.

BFD is a UDP protocol.

• BFD control : UDP / 3784
• BFD echo : UDP / 3785

BFD is in use on a segment, when a protocol needs it (such as : OSPF). It is configured by interface and called in protocol configuration. When BFD detect a failure it informs upper protocols and helps to make a better / quick convergence.

To understand well path through new chassis such as ASR9K, you could see this video (from Cisco Live 2014) and this blog post written by Ivan Pepelnjak, CCIE#1354. You could make a join between VOQ for QOS and LPTS/VOIP for ASR9K.

Have fun :)

It is not a news for CCIE student that today is the last day to pass CCIE lab in version 4. I hope the best for all the students whom will work hard today towards their digits.

Tomorrow is future : CCIE v5 is here. It is the version I will pass. A little review :

Bye bye to :
