Is there any updates from INE on when more labs will come?
It would be nice to get some more Foundation labs and even some TS or full scale labs.

Dears,
The authorization policy is missing from the solution of the task LWA using ISE.
We need to add a condition RADIUS: Service-Type equals OUTBOUND and assign it to WEBAUTH authorization profile.

BGP Tasks : Biggest confusion
very simple if you look at the diagram clearly it shows
R1,R4,R6 (AS 100)
R2,R3,R5,R8 (AS 200)
R7 (AS 300)
R9,R10 (AS54)
But the solution at page 715-717 clearly says all the AS in 100 why ????????????????????????????/ It is really frustrating for me ....Can anyobe here guide me why is it like this ??????

EIGRP Summarization with Default Routing
Hi,
I have a problem for this task.
R4 is generating a default route in the tunnel0
interface Tunnel0
ip summary-address eigrp 100 0.0.0.0 0.0.0.0 leak-map CONNECTED-TO-EIGRP
I used a leak-MAP using the same route-map that for the redistribution in the eigrp process just to check.
In R5 everything "seems" fine
R5#sh ip route | be Gate
Gateway of last resort is 155.1.0.4 to network 0.0.0.0
D* 0.0.0.0/0 [90/25856256] via 155.1.0.4, 00:04:16, Tunnel0
4.0.0.0/24 is subnetted, 4 subnets
D EX 4.0.0.0 [170/130816] via 155.1.45.4, 00:04:14, GigabitEthernet1.45
D EX 4.0.1.0 [170/130816] via 155.1.45.4, 00:04:14, GigabitEthernet1.45
D EX 4.0.2.0 [170/130816] via 155.1.45.4, 00:04:14, GigabitEthernet1.45
D EX 4.0.3.0 [170/130816] via 155.1.45.4, 00:04:14, GigabitEthernet1.45
But in fact we can see that we can reach these subnets via the g1.45 interface, not the tunnel 0, but no problem with the 0.0.0.0/0
I have a problem with the summarization.
And on R1-R3 i have only the leaked routes
R1# sh ip route | b Gate
Gateway of last resort is not set
4.0.0.0/24 is subnetted, 4 subnets
D EX 4.0.0.0 [170/27008256] via 155.1.0.5, 00:06:20, Tunnel0
D EX 4.0.1.0 [170/27008256] via 155.1.0.5, 00:06:20, Tunnel0
D EX 4.0.2.0 [170/27008256] via 155.1.0.5, 00:06:20, Tunnel0
D EX 4.0.3.0 [170/27008256] via 155.1.0.5, 00:06:20, Tunnel0
With a debug on R5 i have this:
R5#debug ip eigrp 100
Then i do on R4
clear ip eigrp 100 neighbors 155.1.0.5
And on R5 i have this output:
[...]
EIGRP-IPv4(100): table(default): 4.0.1.0/24 - do advertise out Tunnel0
EIGRP-IPv4(100): table(default): 0.0.0.0/0 - do advertise out Tunnel0
EIGRP-IPv4(100): table(default): 4.0.0.0/24 - do advertise out Tunnel0
EIGRP-IPv4(100): table(default): 4.0.2.0/24 - do advertise out Tunnel0
EIGRP-IPv4(100): table(default): 4.0.3.0/24 - do advertise out Tunnel0
EIGRP-IPv4(100): table(default): 4.0.1.0/24 - do advertise out Tunnel0
[...]
But i don't seem to get this route on the R1-R3 routers...
Not in their topology table either.
but if i use the summarization on R4 on the G1.45 instead of the tunnel0, it works fine
R4(config)#int tun 0
R4(config-if)#no ip summary-address eigrp 100 0.0.0.0 0.0.0.0 leak-map CONNECTED-TO-EIGRP
R4(config-if)#int
%DUAL-5-NBRCHANGE: EIGRP-IPv4 100: Neighbor 155.1.0.5 (Tunnel0) is resync: summary configured
R4(config-if)#int g1.45
R4(config-subif)#ip summary-address eigrp 100 0.0.0.0 0.0.0.0 leak-map CONNECTED-TO-EIGRP
R4(config-subif)#
It now works fine...
R1# sh ip route | b Gate
Gateway of last resort is 155.1.0.5 to network 0.0.0.0
D* 0.0.0.0/0 [90/26880512] via 155.1.0.5, 00:00:48, Tunnel0
4.0.0.0/24 is subnetted, 4 subnets
D EX 4.0.0.0 [170/27008256] via 155.1.0.5, 00:08:26, Tunnel0
D EX 4.0.1.0 [170/27008256] via 155.1.0.5, 00:08:26, Tunnel0
D EX 4.0.2.0 [170/27008256] via 155.1.0.5, 00:08:26, Tunnel0
D EX 4.0.3.0 [170/27008256] via 155.1.0.5, 00:08:26, Tunnel0
If I use summarization on tunnel 0 on R4 without the leak-map i have nothing. The problem seems to be with the default route only.
And by the way eigrp seems to work smoothly
R5#sh ip eigrp neighbors
EIGRP-IPv4 Neighbors for AS(100)
H Address Interface Hold Uptime SRTT RTO Q Seq
(sec) (ms) Cnt Num
1 155.1.0.4 Tu0 14 00:03:52 12 1476 0 38
3 155.1.0.1 Tu0 14 00:38:54 1 1476 0 12
2 155.1.0.2 Tu0 13 00:38:58 1 1476 0 37
0 155.1.0.3 Tu0 14 00:38:58 1 1476 0 45
any idea ?
[EDIT]
It seems i have a problem in my DMVPN topology.
I can't join 155.1.0.4 from R1-R3...
If i fix it i think everything should be fine
[EDIT2]
So dumb... I used the command
no ip split-horizon
instead of
no ip split-horizon eigrp 100
on the tunnel0 interface of R5.
Everything is fine ...

CCIE Recertification Question
I have a question about CCIE recertification. I recently passed in Jan 2014 my R/S. I am pursueing the SP track now but have not taken the written.
My question is, if I take the SP wrttien today will it count as a recert and give me +2 years? Or do I have to wait until Jan 2015 for it to count.

7.47 BGP Regular Expression, why R3 has configuration?
Hi,
I can see other peoples' opinions on why R3 can be used to make 7.47.3 work but the WB clearly states that the configuration change is required on R5. There are solutions on the forums that claim to make it work and I think I can do it by adjusting the LP for the other routes to be lower than those through R3 but can anyone explain to me why the WB has the R3 configurations in it?
Thanks.

6509 VSS Setup
Hello community,
I came across a VSS setup where the etherchannel ports used for VSS communication are configured as L3 ports and the Port-Channel interface is configured without an IP address:
int t1/1/1
no switchport
channel-group 11 mode on
!
interface Port-channel11
no switchport
no ip address
switch virtual link 1
Is this an acceptable configuration? I seems to work but I am a bit confused as to how the VSS members are maintaining the link by communicating with each other without an IP. Thoughts anyone?
Thanks in advance

Graceful Restart Doubts
Hi all,
I understand from a high level that GR helps with routing engine switch overs, for example a failover of 6500 supervisors, by suspending the control plane while maintaing the forwarding plane.
The bit that confuses me and unfortunately I don't have the kit to test is what happens if a supervisor just dies? For example if I ripped out the active supervisor?
This would not be very "graceful" and there would be no chance for the device to signal that it needs to switch over.
So my question is simple: Does GR help with sudden, catastrophic failures in dual supervisor systems?
Many thanks!

BGP Bestpath Selection - Always Compare MED
Hi
Currently I'm wokring on the task mentioned above. The task is to configure MED in a way that all traffic sent from AS200 to the loopback interface 1.2.3.4/32 is received by R7. After I configured everything I comapered my configuration with the solution. Everything seems to be okay and the routing table on R5 looks fine:
R5#sh ip bgp 1.2.3.4/32
BGP routing table entry for 1.2.3.4/32, version 19
Paths: (2 available, best #2, table default)
Advertised to update-groups:
12 13
Refresh Epoch 3
100
155.1.45.4 from 155.1.45.4 (150.1.4.4)
Origin IGP, metric 1000, localpref 100, valid, external
rx pathid: 0, tx pathid: 0
Refresh Epoch 2
300
155.1.37.7 (metric 3584) from 155.1.0.3 (150.1.3.3)
Origin IGP, metric 100, localpref 100, valid, internal, best
rx pathid: 0, tx pathid: 0x0
Now the traffic should go to 155.1.37.7. But the route to reach 155.1.37.7 (learned via IGP) still goes through R6. Show ip route 155.1.37.7 shows 155.1.45.4 as next hop. So my packets sent to R7 are answered by R6 and not by R7. I my eyes the solution in the workbook is wrong. Or am I missing something?
Regards & thanks!

Erasing the interface config
Dear All,
I was doing some Classing Ethernet switching labs from Nexus Technology workbook using INE Rackrentals.
I heard that "default interface [interface-id]" does not work with Nexus 7K but when I tried it during Rack rentals it worked.
Is it due to code that the N7K is running or is it due some type of alias commands configured on N7K.
Can someone help me on this.

Anyone else through the advanced tech labs and trying to figure out where to go next?
First off, I'm not complaining :)
I finished the labs about a week ago and have since started trying to find my areas that could use some improvement. I honestly don't want to touch the v4 foundation labs..but might not have an option if I want to keep progressing.
Just curious who all else is in this boat, and what are you doing to keep yourself busy?

1.6 Redistribution - Native RIP routes on R3 and R4
The solution states:
Now the same thing but for RIP: we should only see native RIP routes on R3 and R4. All EIGRP routes are preferred via OSPF.
R3 looks good but R4 has the OSPF route between R1 and R3 in its RIP routes table (10.0.13.0/30). Is that meant to be there?

OSPF External Summarization
In EIGRP redistribution section, config is using prefix-list to match the prefix and using that int route-map.
In this section, config is using interface to match in route-map (match interface lo100 lo200)
Are there any reason, or this is arbitrary?
I tried both prefix-list matching and interface matching, and it seems both are working. I'd be glad if anyone tell me if I'm missing something.

Does anyone know an iou version that allows fast-reroute? My 15.3T does not allow it and its part of several initial configs, also the distributed option on ip multicast-routing does not seem to work either...
Brian are these integral to solving the lab or setting up the scenario?? If not cool if they are then using iou is going to suck 😐 !
