To round off Redistribution series of posts for Dynamic Routing Redistribution, what better way to drive it home, than to Redistribute every Dynamic Routing Domain into every other one and see what we can break? There will be a LOT of output from this lab to demonstrate how to verify and configure / troubleshoot everything … Continue reading TSHOOT – Redistribution Part 5 – The OSPF / EIGRP / BGP / Redistribution lab!
Above is the IP Packet Switching architecture, with the IP Route / ARP Table at the "Control Plane" at the Top, which then feeds the FIB (Forward Information Base) aka IP CEF and Adjacency Table to perform Hardware Packet Switching. Packet Switching is covered extremely in depth in this article, however it will be briefly … Continue reading TSHOOT – IPv4 Route Selection / Packet Switching process, Static Routing for IPv4 and IPv6 with troubleshooting!
Not /fin with this Topology of course, after this lab of fine tuning some sub-optimal routing I am taking copies of all "sh run" to be able to spin this lab up again if it ever gets the "wr er", however it will be /fin for review and onto the subject of VPN's. So, Part … Continue reading Part 6: Troubleshooting of sub-optimal routing via route-maps / redist/ policy routing, and an old friend OSPF distance comes to save the day! (GREAT review!)
I took a quick moment to post before this, advising not to study or lab tired, cause as can be seen towards the end of my Part 4 of this lab I am just tired and swinging at air. Anyway, we now have R1 and R3 both acting as ASBR's, with R1 doing 2-way route-tagged … Continue reading Part 5: Turning “IP Routing” on for Layer 3 SW1, Policy / Local Policy Routing, found sub-optimal routing due to AD! (Will be 6th lab to troubleshoot)
This is using the same Topology setup as the RIP / OSPF Redistribution posts, however as noted in micro-text on the Topology below, I've changed the OSPF Area 0 to EIGRP AS 100, and removed any loopbacks in the EIGRP route domain as they are not necessary for now: To change the metric or 'seed … Continue reading EIGRP Redistribution – Changing Metric and AD
I will be using the same Topology for this lab to demonstrate 4 different ways to Redistribute OSPF routes, using the same Topology as before as follows: I removed the static route from R5 as a return route to RIP land, and will now be doing 2 way redistribution between the routing domains, but first … Continue reading OSPF to RIP, 4 ways to change AD, Sub-Optimal Routing & Route Loops
