Resolve Common PC Errors
In this user guide, we describe some possible causes that might lead to route redistribution troubleshooting, and then I suggest some possible fixes that you can try to solve this problem. To allow redistribution when the redistributed path does not appear in the navigation table: Ensure that the above route is simply not advertised by another routing protocol that claims a lower administrative distance. For example, if you distribute version 10.1. 1.0/24 interest in EIGRP from BGP and bundle 10.1.
When it comes to distribution, a lot of things can be bought wrong. Two potential problems are suboptimal routing trends and routing loops. All redistribution problems boil down to two new problems:
If you haven’t seen my first driving lesson on redistribution related to metrics, I recommend you start there first. When you finally learn how to solve problems with metrics, this lesson will become a little more clear.
In this course, we explore the redistribution problems caused by administrative distance. I will also explain why this is happening and of course how to fix it !

And what the routing tables usually look like, our organization hasn’t set up redistribution yet:
Show route R2#IPC 192.168.12.0/24 connected directly, FastEthernet1/0 i .0.0.0/24 is in subnets, 1 subnetR 22.214.171.124[120/1], e.g. 192.168.12.1, FastEthernet1/0C 00:00:28, 192.168.24.0/24 directly connected, FastEthernet0/1C 192.168.23.0/24 bound, directly FastEthernet0/0D 192.168.34.0/24 [90/307200] to 192.168.24.4, 00:00:33, FastEthernet0/1
R2 finds R1 prefix from RIP and learns engineering solutions between R3 and R4 (192.168.34.0/24). Let’s see by visiting IP r3:
r3#Show routeD 192.168.24.0/24 [90/307200] to 192.168.34.4, 00:01:23, FastEthernet0/1C 192.168.23.0/24 must be connected directly, FastEthernet0/0C 192.168.34.0/24 really direct FastEthernet0/1
R3 is connected by requesting information about the network (192.168.24.0/24) in the rrn between R2 and R4 via EIGRP. Let’s check out R4:
What is redistribution of routing protocols?
Redistribution occurs when an inspection protocol is used to declare patterns obtained in other ways, such as static routes, parallel routes, or another inspection protocol.
R4#show IP routeC 192.168.24.0/24 connected directly, FastEthernet0/0C 192.168.34.0/24 connected exclusively, FastEthernet0/1
R4 didn’t study so much money. This is an internal EIGRP hub, and the only two interfaces that experts say are advertised.Mated in EIGRP, these are R4 external interfaces.
How do you fix routing problems?
Verify that the routing protocol is bound and can use the correct adapter adapter.Look for wireless routers between neighbors.Check your router passwords.Check area IDs.
In order to provide dual connectivity, we have set up redistribution in the marketplace. However, let’s say we have certain requirements… something you might encounter in the R&S CCIE lab exam:
How do you redistribute a route?
Set the default metric considering that all routing protocols are redistributed within this routing protocol.Specify stats aspart of the redistribution command.Define an absolute metric with a roadmap.
If we set up this distribution, there should be a full connection. Check out the main diagram below:
You can see above where we distribute. Without getting too bogged down in this topology, let’s get down to business and set up redistribution:
R2(config)#rip routerR2(config-router)#eigrp 1 redistribute metric 1R2(config)#eigrp Router Rip 1r2(config-router)#redistribute metric 1000 100 255 4 1500
R2 now distributes between RIP and EIGRP. Let’s set up R3:
R3(config)#eigrp router 1R3(config-router)#retribute ospf 1 metric 1500 one hundred dollars 255 1 1500R3(config)#ospf router 1R3(config-router)#eigrp subnet per person
It’s easy! The redistribution was realThe military is proud, so we must be ready to connect, right? We have to check if everything is achievable…
Why do we use route redistribution?
Brief definition: Route redistribution can be a process that allows an infrastructure to use one routing protocol to dynamically route traffic based on resources obtained from a different routing mode. Route redistribution improves availability on fewer networks.
If you’re setting up redistribution and your goal is to ensure full connectivity, you should probably try to check the topology against all IP addresses. The fastest method on the market is to get most of the IP addresses using internet aliases and then use the illegal TCLSH program. Here’s how:
