Redistribution 1 Fundamentals And RIP OSPF Redis













Lets just verify rip is running (we can see we have changed to rip v2 and no auto summ..)



and R1 is picking up the ethernet segment off from R3.....



R2 currently see's no rip routes (as expected) lets changed that and get R1 distributing them routes into RIP




Notice R2 is not receiving the route ... and that is because we did not specify a SEED METRIC, even though we took the legal command, it will not shout at you! ... so


lets specify the seed metric for the redistribution ...


And now R2 sees them routes...but that doesn't mean we have connectivity!, lets see...




Looks like we have a problem at R1 ... we need to put the RIP routes into OSPF, as R3 doesn't know how to get back to the RIP domain ...





Here is the config of R1

Redistribution 2 RIP And OSPF Lab





So, R2 and R3 can see the ethernet segment behind R1, but R4 and R5 cannot,


so lets fix that with some redistribution.


Nicely done and confirmed in the routing table of R4, we can see the networks.


HOWEVER, look at what route R2 now has to get to the ethernet segement, its now not seeing the RIP route, but the redistributed route from OSPF, as OSPF AD is 110 and RIP is 120!
