ip route problem

[e-mourad]

Hi,

Please can someone help me. my config of the Internet router is :

Gateway of last resort is 192.168.101.17 to network 0.0.0.0

10.0.0.0/8 is variably subnetted, 2 subnets, 2 masks

S 10.0.0.0/8 [1/0] via 10.1.128.1

C 10.1.128.0/24 is directly connected, Ethernet0

192.168.101.0/30 is subnetted, 1 subnets

C 192.168.101.16 is directly connected, Serial0

193.95.122.0/32 is subnetted, 1 subnets

C 193.95.122.247 is directly connected, Serial0

193.95.116.0/29 is subnetted, 1 subnets

S 193.95.116.8 [1/0] via 10.1.128.1

S* 0.0.0.0/0 [1/0] via 192.168.101.17

to insert the route 193.95.116.0/29 i have typed this command :

ip route 193.95.116.8 255.255.255.248 10.1.128.1

The 10.1.128.1 is the interface of the PIX.

But the problem is, when i try to ping for example :

193.95.116.220 :

C:\Documents and Settings\EMOURAD>tracert 193.95.116.220

Détermination de l'itinéraire vers 193.95.116.220 avec un maximum de 30 sauts.

1 2 ms 3 ms 3 ms 10.1.128.3

2 10.1.128.3 rapports : Impossible de joindre l'hôte de destination.

Itinéraire déterminé.

The router 10.1.128.3(Internet).

Whats is wrong ?

Thanks

Hello,

can you do a 'clear ip route *' and then a 'show ip route 193.95.118.200' on the router where you added the static route ?

Just to make sure can you also flush the routing table on your workstation (route -f) where the traceroute originates ?

And last but not least are you sure the host is up ? Assuming that the address 193.95.116.220 is a public address from Planet Tunisie, I am unable to reach this address from the Internet, but it might be that there is a firewall stopping the ping.

Regards,

GP

Hello,

the problem is that the local router (10.1.128.3) himself indicate that it cannot rich the destination @. When i desactivate the route 193.95.116.8 255.255.255.248 and i use the public network 213.150.188.192 255.255.255.240, i can ping this @:193.95.116.220 and i cannot ping for example 213.150.188.243.

It is like that the local router (internet) use the route 213.150.188.0 255.255.255.0 !

Thanks

Hi e-mourad,

Please make sure your router has a "IP classless" command in the configuration.

In your configuration, there is several network classes (10.0.0.0, 192.168.101.0, 193.95.122.0 and 193.95.116.0) in your router. If a router is "classful", it will "think" that itself is a part of the major network class. Then, if there is not a match route list under that major network, router will drop the packet instead of use the default route.
