How to configure Route Redistribution of BGP, OSPF and EIGRP in Cisco Packet Tracer

By Karan Ratta


Route Redistribution


It is straightforward to put together route redistribution of EIGRP, OSPF & BGP in Cisco Packet tracer. Basically, Route distribution permits routes from one routing protocol to be publicised into another routing protocol. It's preferred to use one routing protocol in  internetwork surroundings, for simplicity and easy management. Sadly, this can be not invariably doable, creating multi-protocol environments common. Routes can solely be decentralized if they exist within the routing table. Routes that area unit merely in a very topology info.


At least one distribution purpose must exist between the 2 routing domains. This device can really run each routing protocols. As you'll be able to see in upper diagram, the yellow section contain 2 router connected with one another through serial link .


Router 1 runs OSPF protocol.
Router 2 runs OSPF and BGP protocol.
Router 3 runs EIGRP and BGP protocol.
Router 4 runs OSPF protocol.


Configuration of Router 1:

In Router one, I actually have put together the OSPF and advertise the network 192.168.80.0 & 192.168.70.0 in space zero. As you'll be able to see in upper image, four routes area unit shown in which initial & second routes area unit External 2 sort routes of EIGRP network. Static routes and connected interfaces is decentralized into a routing protocol as well. during this workplace I actually have not designed static routes as a result of i would like to indicate you the redistribution of dynamic routing protocols only. therefore If you guys wish to feature the static routes go ahead!! there's no issue however you have got to feature up the one command and that is redistribute static


router ospf 10
log-adjacency- changes
network 192.168.80.0 0.0.0.255 area 0
network 192.168.70.0 0.0.0.255 area 0

Route Redistribution Configuration of Router 2:

In Router 2, I actually put together the OSPF as well as BGP and advertise the network 192.168.70.0/24 and redistribute the bgp 200 (remote-AS) subnets in OSPF. As you can see in upper image, four routes area unit shown during which initial & second routes area unit external a pair of sort routes of EIGRP network



router ospf 10
log-adjacency-changes
redistribute bgp 200 subnets 
network 192.168.70.0 0.0.0.255 area 0
!
router bgp 200
bgp log-neighbor-changes
no synchronization
neighbor 192.168.30.1 remote-as 100
redistribute ospf 10 match external 1 external 2 

Route Redistribution Configuration Router 3 :



Yeah!! same thing I have done router 3 however the sole distinction is actually have amendment the ospf protocol than EIGRP and distribute the routes with one another. When I run the command distribute in EIGRP section the metrics area unit like that 1554 may be a bandwidth of a link, 20000 may be a delay time in small second, 255 may be a responsibleness, 1 is refer as a Load and eventually 1500 may be a MTU (Maximum Transmission Unit). Routing metrics area unit a key thought once play acting route distribution.


router eigrp 10
redistribute bgp 100 metric 1544 1 255 1 1500 
network 192.168.20.0
auto-summary
!
router bgp 100
bgp log-neighbor-changes
no synchronization
neighbor 192.168.30.2 remote-as 200
redistribute eigrp 10


And the last but not the least is Router 4 in this router you just have to advertise the network through EIGRP . In below configuration, I have advertised two networks 192.168.10.0/24 and 192.168.20.0/24 .

router eigrp 10
network 192.168.10.0
network 192.168.20.0
auto-summary

So, this is all about route distribution I hope this article will help you to understand the concept of route redistribution. If there is any query related to this article just comment below. Thank You Guys :)

Signup table id int (5) email varchar (100) username varchar (50) photo varchar (150) password varchar (25) 2. Request table id int (5) from varchar (100) email varchar (100) 3. My Friend table id int (5) email varchar (100) friend varchar (100) Send Friend Request : This is the first step in which you have to send friend request to the person and it depends on him ...
