  • @survivorman said: As I understand the only choice I have now is plain old buddy GNS3. Does INE have pre-built lab versions for it? I haven't found. For VIRL or GNS3? For VIRL there is the INE GitHub, but the only thing useful due to t…
  • There is no tacacs server available. The purpose of the lab was show you how to configure it. In the end one falls back to either local, line or enable locally when the tacacs is not available. It was not intended to be successful
  • In IGMPv1 the DR and the querier were on a single box. There was no concept of a "Leave Message" Only lack of membership requests for a specific timeout period would then stop a feed. "So one router hears that a receiver exists in the segme…
  • No, FIFO will never discriminate or give preference to higher-priority packets.

  • It appears to be based on the physical topology available in the CCIE R&S v4 Troubleshooting Rack Rental based on the configuration files available in the course files. Not based of the virtual topology in the CCIE Routing & Switching v5 …
  • Adapt the tasks: Make your own diagram which is good practice Copy the task from the web page and do a search replace of the interface designations if you can't dynamically adjust to the changes.
  • You can buy VIRL subscription for $200 and set that up...it should give you access to all platforms. Careful recommending a product that has limitations associated with the specific platform he wants to work with [Nexus].  He mentioned VPC, which …
  • It is being filtered, but now you are using the internally learned less specific prefix that was there before.  It was not used as there was orginally a more specific route. Before: Routing entry for 111.111.1.0/24   Known via "eigrp 100", dis…
  • I used to work with Travis previously.  He is very knowledgeable and his videos are great.
  • Try removing  dot1x pae authenticator, I believe that disables multi-host authentication Also, side not I do not see where you have specifically identified a data vlan.   Unless you are looking for it to default to vlan 1
  • 1. after turning on the phone, it will be initially member of the data vlan. so we need to use the "helper-address" command on the data vlan SVI on the switch. am I right? (the default gateway of the data vlan is on the another device, rather than t…
  • SW2 on sends ADVERTISEMENT REQUESTS to the server and those requests do not contain MD5 hash in them.  You will not log a mismatch on SW1. SW1 being the server sends SUMMARY ADVERTISEMENT MESSAGE which does contain the MD5 HASH, so only SW2 will s…

  • run "debug sw-vlan vtp events" on the switch that is not receiving the update. For fast result, shut down and activate the trunk interface

  • The network is 10.3.100.0/22. First Host Address is 10.3.100.1 Number of Hosts: 1022 (2 to the 10th - 2) = 1022 Last Possible Host is  10.3.103.254 Broadcast Address  is 10.3.103.255   Answer still is that 10.3.104.95 would not fall with…
  • How was it before you took down the link, you did not really say?  Have a read on path selection. http://www.cisco.com/c/en/us/support/docs/ip/border-gateway-protocol-bgp/13753-25.html
  • The topology files are on the github site, you just need to import them into VIRL as apposed to manually recreating the topology.
  • Github repository can be found HERE , has everything you need. 
  • https://github.com/Internetworkexpert/INE-VIRL
  • Is "dot1x system-auth-control" required in global config to enable 802.1x on the switch? EDIT: You may have not showed it in the provided config, as you just provided what was requested. the switch didn't learn the mac address of the device. …
  • Separate management routing table would not fix this. The separate management routing table showed up as a requirement so that a user in VLAN x, which is reachable by the ASA on the inside interface, can now also manage the ASA on its management int…
  • Hi, This is a restriction per ASA architecture. You cannot send any management-plane or control-plane traffic through the ASA, it only works towards the interface closest to you from routing point of view, like in you case towards 10.0.0.1. ICMP…
  • Read the following section on How Routing Behaves Within the ASA to include Egress Interface Selection Process & Next Hop Selection Process. http://www.cisco.com/c/en/us/td/docs/security/asa/asa91/configuration/general/asa_91_general_config/ro…
  • Unless you are running 9.5 code where the management interface gained the ability to have it's own routing table, the traffic would come in managment and go out whichever interface had the default route.  When the management-only command is enabled…
  • He referenced 101/1/1 on both switches, no other port, which would logically mean enhanced VPC, no port channel.  He certainly could be doing other things, I was just basing off the information he gave.   You are correct if Dual homed configur…
  • 101/1/1 is the same physical port, just two parent switches.  There's no need to make it a port channel You are correct if his goal is not to establish a port-channel on the server.  I assumed that per him discussing VPC. If that was his goal, t…
  • vPC can interoperate between different versions of NX-OS during upgrade or downgrade Not sure you would have and issue generally although not recommended, but there is a potential to affect VPCs to end host if the MAJOR revision number is differe…
  • VPC+ is for fabricpath as already stated.  I am assuming your two switches are already peered. However to place in VPC your configuration is incomplete.  One needs to assign each to a PO and assign PO to VPC: N5K-10> interface e101/1/1 swit…
  • Are you fully meshed or running route-reflectors
  • You have a laptop with 64 GIG RAM ?  WoW ..... I want it and want it now!   The new Dell Precisions 7510s and 7710s with Skylake processors can handle up to 64Gb of memory.  Lenovo has some also.   My desire was to have a mobile lab I co…
  • I just started going through some of the layer 2 myself.  Do not have a complete list yet of what does not work.  I have been porting over physical configs to VIRL and doing labs. I am running a 30 node license.  I run 20 IOSv routers and 4 Layer …
