Solved: redistributing routes using distribute-list

sarahr202 · ‎12-15-2012

Hi everybody

My book says we can use " distribute-list with " out" option to redistribute routes.

I have been trying to test this feature but I can not get it working.

Below R2 is supposed to redistribute route 1.0.0.0/8 learned via rip into eigrp using distribute list.

loopback 1.0.0.0/8( R1)-----rip---------f0/0 (R2)---f0/1---Eigrp----R3

R2#show ip route

Gateway of last resort is not set

C    200.200.200.0/24 is directly connected, FastEthernet0/0
C    199.199.199.0/24 is directly connected, FastEthernet0/1
R    1.0.0.0/8 [120/1] via 200.200.200.1, 00:00:22, FastEthernet0/0

router eigrp 1

network 199.199.199.0

default-metric 100 10 255 1 1500

distribute-list 4 out rip

auto-summary

access-list 4 permit 1.0.0.0 0.255.255.255

I am expecting 1.0.0.0 should be redistributed into eigrp and R3 should have it in its routing table:

But It does not:

R3#show ip route
C 199.199.199.0/24 is directly connected, FastEthernet0/0
R3#

I have pasted the show runnning outputs below.

Thanks and have a great weekend.

Hi

Function of Distribute-list is to filter the routes. It cannot do redistribution

You need to use redistribution command for redistribution to work from RIP to EIGRP

Thanks

Hi Raju

That is exactly I thought. But the book says we can also use distribute-list with " option" to redistribute routes into igp

It also gives an example but when i lab it up, I don't see any routes being redistributed.

Thanks anyway.

I would look for a better book, if I were you.

Which book is it? We need to contact the author/publisher to get it corrected if possible.

Hi

"distribute-list 4 out rip"

The RIP in the end says to apply the distribute-list only for RIP routes. But still you need redistribution statement

Thanks
