Cisco has released recently lot of materials to be friend with their new technologies. You can know learn more about IOS XE with Cisco CSR1000v (it is a virtual router based on Cisco IOS XE code) and more recently (02/07/14) you can download Cisco IOS XRv 5.1. You can download it as a demo version (2M of bandwidth, AAA preconfigured, … : some restrictions). It is a virtual machine that you can import in VMware ESX VM.
I think it will be really great to learn, practice over IOS XR without any risks (for those of us who can log in some real ASR9000 or CRSX3, …).

A really, really good documentation :
I urge you to read this PDF… Thank you fryguy !

It is been a while I check forums and Ubiquiti products. They are really good products. At the beginning the really interesting thing in ubiquiti was the Open minded / Open Source direction they used. I begun to use their product with SR and XR card (when they don’t seek any final products). It was really easy to make your own product firmware with an embedded MIPS motherboard and their cards. The SDK was available at this time.
I check recently and now it is not. Ubiquiti has been introduce in Wall Street. I am really disappointed because when I was interviewed by them for their papers to be introduce to Wall Street I insisted on the fact of they success OpenSource is one main of it.
I would want to make some patch on kernel to be able to pass PPP/IP DSCP to their Atheros card to be able to do the same thing with IP (http://wiki.ubnt.com/AirMax_-_QoS_DSCP/TOS_Mappings). Now SDK is not available and I am really disappointed.

For those of us like me who are working towards CCIE, you are certainly aware of the fact that CCIE v4 will be raised to v5. For INE.com, it seems that Frame-Relay (replaced by DMVPN), and some other features will be replaced.
I am studying really for fun now : I am studying Frame-Relay now

This a question which I ask for a long time : is this e Cisco CEF equivalent on Redback router ?
A friend gives me the answer :
[VRF_FOOBAR]75TOTO-SE400-01#sh ip route 172.16.116.98
Longest match Routing entry for 172.16.116.98/32 is 172.16.116.98/32 , version 20
Route Uptime 38w6d
Paths: total 1, best path count 1
Route has been downloaded to following slots
Path information :
Active path :
Known via adjacency, type-hidden route, distance 254, metric 0,
Tag 0, Next-hop 172.16.116.98, NH-ID 0x3450014E, Adj ID: 0x160, Interface 1/5.13717
You can see there that the packet will live the router by port 1/5. You can confirm this by :
[VRF_FOOBAR]75TOTO-SE400-01#show card all fib 172.16.116.98
Prefix Next Hop Interface Next Hop Grid
172.16.116.98/32 172.16.116.98 1/5.13717 0x3450014e
Now, you can see as « sh ip cef … adjacency » :
[VRF_FOOBAR]75TOTO-SE400-01#sh card 1 adjacency | begin 0x3450014e
Encap type dot1q, function ether_dot1q_adj_ip_resolved

0030 88147df0 : source MAC address

18 : length
For VLAN ID here :
1/5 vlan-id 3717 Up dot1q interface 1/5.13717@VRF_FOOBAR
To make a point :
./configure && make
