There is still some kind of crappy limitation with GNS3 and getting my Loopedback VLAN to communicate with the PC devices in ACME Co LAN - However I do have reachability on the Network Devices to play with some local configs in this lab! I have just recently started to use GNS3 and am not … Continue reading Python3 Network Programming – NAPALM for Network Device Configuration, lots of troubleshooting and good to knows for Network Engineers in this content (which will be continued)!
There was some lack of depth in my review of ACL's in general, so wanted to jump on my lab to demonstrate some output and concepts for on the job and the exam room. If you read absolutely nothing else in this post, jump down to the bottom where a chaotic looking IPv6 ACL line … Continue reading TSHOOT – IPv6 ACL configs, quirks, and must know IPv6 subnetting for exam day!
Only the NBMA and Ethernet segments will be used for quick demonstrations and clarity, unless R4 or R5 is needed for demonstration. The first mechanism specifically for EIGRP to filter EIGRP learned routes is by distribute lists, which have a similar syntax structure and function in ways as an offset-list, in the ways that: It … Continue reading EIGRP: DEEP Dive into Route Filtering with Distribute-Lists using ACL’s – Important notes on using Extended ACL’s for exam day!
So as can be seen we have no NBMA in this topology, only Serial Links and an Ethernet segment, which almost makes feel naked without a Frame-Switch in there somewhere. So to begin, my last post included on the tail end a "sh ip bgp" to demonstrate something with a bunch of loopbacks being advertied … Continue reading BGP – The Multi-Exit Discriminator (MED) / Metric explained, configured, and we see some old friends ACL’s and Route-Maps to help accomplish the goal!
I'm was going to wait for the NTP part of the course to go through this, but since it looks like ACL material finishes with this I will use the time-range command for now rather than synchronizing the network to an NTP server. A bit of a refresher from CCNA material, but it can't help … Continue reading Time based ACL’s, configuring time-range and differences in types of ranges, using time-based ACL’s to limit telnet access
I was going to just use two routers for this example, after work when I was tired and rushing, so I stopped and decided to be thorough I didn't want to work with loopbacks. So please forget the Stub things in the topology, those area's are not stubs, however the OSPF information is correct. Also … Continue reading Access-List Refresher: Standard, Extended, and Named ACL’s – Very good refresher material, some of this material like best practices I had even forgotten
