Can you paste the routing config ?

As requested by Satish, please post

1) Configuration details

2) routing tables

3) An explanation of which statics work and which don't.

Are you redistributing statics into EIGRP ?

Jon

i have EDS Switch which have static route 192.72.24.0 which is not advertised to Access Switch thats why i have to write a Static route, i dont know why only this route is not shown in Access Switch my routing table but have others.although i have it in my EDS Routing Table

attached is the configuration of both the 3750 Switches.

Could you clarify. Are any of the static routes on EDS switch showing up in access switch routing table ?

You are not redistributing static routes into EIGRP on EDS switch so it wouldn't get to the access switch.

Apologies if i have misunderstood what you are asking.

Jon

yes if you see the routing table of access Switch you can find routes to 172.16.0.0 and other static routes in EDS switch

like

ip route 10.0.0.0 255.240.0.0 10.4.0.13

ip route 10.16.0.0 255.240.0.0 10.4.0.13

ip route 131.2.60.0 255.255.255.0 10.4.0.13

ip route 151.1.2.0 255.255.255.0 10.4.0.13

ip route 151.2.0.0 255.255.0.0 10.4.0.13

ip route 172.16.0.0 255.254.0.0 10.4.0.13

ip route 172.18.0.0 255.254.0.0 10.4.0.13

ip route 192.168.0.0 255.255.255.0 10.4.0.13

except 192.72.24.0

Post the output of "show ip route" from both devices please.

The reason why the static routes are not being advertised into EIGRP - is because you have not configured EIGRP to advertise static routes.

Thanks i must redistribute STATIC

Hi Guys,

How can you configure EIGRP to advertise static route? Thanks in advance.

Cheers!

Under your EIGRP configuration

router eigrp 1

redsitribute static

Note that you can use a route-map with the redistribuet static if you only want to advertise some of your statics.

Hi Jon,

Thanks for the reply. Can you please give me a link on where I can study it more deeply? I am not sure If programming statement can also be applied to Network configs like for example:

If this packet came from this destination

then perform this operation.

:-)

Thanks.

Cheers!
