eigrp redistribute problem

router_a------router_b

If I config on the router_a:

conf t

ip route 137.1.1.96 255.255.255.224 192.168.1.2

ip route 6.0.0.0 255.128.0.0 null 0

ip route 6.128.0.0 255.128.0.0 null 0

router eigrp 1

redis static route-map stat-e1

route-map stat-e1 permit 10

match ip addr 13

no access-list 13

access-list 13 permit 6.0.0.0

access-list 13 permit 6.128.0.0

access-list 13 permit 137.1.1.96

end

the static route will not redistribute into eigrp as 1,

But if I config like this(cofnig static route at last):

conf t

router eigrp 1

redis static route-map stat-e1

route-map stat-e1 permit 10

match ip addr 13

no access-list 13

access-list 13 permit 6.0.0.0

access-list 13 permit 6.128.0.0

access-list 13 permit 137.1.1.96

ip route 137.1.1.96 255.255.255.224 192.168.1.2

ip route 6.0.0.0 255.128.0.0 null 0

ip route 6.128.0.0 255.128.0.0 null 0

end

everything will ok,why? If I use prefix-list to replace access-list, there is same result.

Are there any bug? Look like IOS will process redistribute correctly only if you config

static route at last. I can't find anything using bug toolkit.

And if I show ip route on router_b

router_b#show ip route

D 6.0.0.0/9 [90/28160] via 192.168.8.253, 01:59:55, FastEthernet1/0/0

D 6.128.0.0/9 [90/28160] via 192.168.8.253, 01:59:55, FastEthernet1/0/0

D EX 137.1.1.96/27 [170/28416] via 192.168.8.253, 01:59:56, FastEthernet1/0/0

Why 6.0.0.0/9 and 6.128.0.0/9 is internal route and 137.1.1.96/27 is external route?

Is it because 6.0.0.0/9 and 6.128.0.0/9 is point to null 0?

They should all be external. Not sure why, I did the same and it worked for me:

What IOS are you running? If possible I would clear the config, reload and re-enter the config. If you can't can you post the show output like above?

Re: eigrp redistribute problem

Steve,

thanks,I can't clear the config because the router is in production.But I test it on a new 2611,result is same.I don't know why,maybe your IOS is different with mine and different IOS has different behavior.

Re: eigrp redistribute problem

Steve,

I upgrade my 26'IOS to 12.1(18),result is same(route which point to null 0 is still internal).

can u tell me what's your IOS version?

regards

Henry

Re: eigrp redistribute problem

It is a lab router so the IOS is older - 12.0(21):

Router_a is learning 6.0.0.0/9 via eigrp 1 and eigrp 18. Can you post the full config (minus IPs/passwds)? What does the network topology look like?

How many peers does router_b have as each route has 4 successors? The external route was learned via eigrp 7 (update from 10.1.96.254) and has a metric of 28416 and the internal routes learned from eigrp 1 (peer 192.168.8.253) with a metric of 28160.

Re: eigrp redistribute problem

Steve,

I download 12.0(21) to my 2600,route is internal,too.I think it is too detail.I don't want waste your time to invesgiate this problem.Thanks!
