This is the second troubleshooting challenge. I would rate this a 2 / 3p ticket.
You can find the configs of the routers here. For those of you using EVE I included the UNL file in there.
The topology is as follows:
R1 wants to be able to reach R6 via telnet. Match the output below.
R1#telnet 2002:C0A8:3806::6 Trying 2002:C0A8:3806::6 ... Open R6>exit [Connection to 2002:C0A8:3806::6 closed by foreign host] You are not allowed to change anything on R4.
This challenge is split up in four parts. Make sure you achieve the desired goals, even after multiple reboots of the routers in your topology.
The initial config files can be downloaded here.
You are not allowed to modify any IP address on any interface You are not allowed to introduce any new interfaces Part 1: IGP.
Configure OSPF area 0 on the links between R7, R8, R11 and R12 Lo0 is part of OSPF area 0 Configure EIGRP as 100 on the links between R8, R9, R10, R13 and R12 Make sure the EIGRP process supports delay measured in picoseconds Lo0 on R10 and R13 should be D EX routes Lo0 on R9 should be part of EIGRP as 100 as a native EIGRP route Configure RIP on the links between R7, R5, R6, R8 and R9 Redistribute between all processes on all possible routers Part 2: iBGP.
This #CCIEChallenge is a troubleshooting ticket for your pleasure. Depending on where you are in your CCIE prep you should be able to fix this ticket in 10 minutes. It would be comparable to a 3 or 4 point ticket.
The config files can be downloaded here.
R1 and R4 should be able to ping each other. Match the following output. R1 should always select its path through R3, even when R3 has suffered a failure and has returned to operations.
So, this is the first CCIEChallenge created by me. You need to achieve the following to pass the challenge:
In the topology, please ignore R15. It has no role in this assignment.

Set up a DMVPN between R14 (hub), R10 and R11 (spokes) This DMVPN needs to use the default route the routers have received from R12. The links between R12 and the other routers are part of the INTERNET VRF, the DMVPN should be member of the global routing table.
Today I’ve created a nice path selection challenge for everybody.
Let’s start with the topology:
IP addressing is simple. The subnets used are 10.0.xx.y/24 where xx are the numbers of the two routers on the link (lowest router first). Y is the router number.
The situation is as follows:
R2 has an eBGP peering with R1. It receives tge default route from R1. R2 advertises this default route to R3 R2 and R3 also form an OSPF network with area 0 R2 forms an OSPF NSSA area 50 with R4 R2 redistributes the connected route to R1 into OSPF R3 forms an OSPF NSSA area 50 with R5 R4 redistributes OSPF NSSA 50 into BGP (including NSSA external routes) R5 redistributes (i)BGP routes into OSPF So the questions are:
