Strange PING result...

[jquintard]

Hello,

A little part of my conf :

interface GigabitEthernet0/1.101
 description Public network
 ip address 11.22.33.44 255.255.255.0
interface GigabitEthernet0/1.110
 description Private network
 encapsulation dot1Q 110
 ip address 192.168.0.1 255.255.0.0
router bgp 12345
 network 11.22.33.44 mask 255.255.255.0

When I ping :

ping 192.168.0.10 source 192.168.0.1

!!!!!

ping 192.168.1.128 source 192.168.0.1

!!!!!

ping 192.168.0.10 source 11.22.33.44

!!!!!

ping 192.168.1.128 source 11.22.33.44

....

Why ? I dont understand...

Hi Jerome,

It probably means that host 192.168.1.128 does not have a default GW (or wrong default GW) configured.

The host have two interfaces. One with 11.22.33.55/24, a second with 192.168.1.128/24. 11.22.33.44 is use as default route. If I ping 192.168.0.1 no problem. If I try to connect on 192.168.0.100 : No route to host.

Hi Jerome,

There is quite a bit of missing information.

What type of OS is host 192.168.1.128? 

What is the reason the router has a /16 as subnet mask and the host as a /24?

Why is host 192.168.1.128 dually connected?

Can you please provide a snapshot of the routing table for 192.168.1.128?

Does host 192.168.0.100 have a default GW? If so, is it 192.168.0.1?

Hi,

Looks like the router for device 192.168.1.128 does not have a route to 11.22.33.44

I dont see any mention of the network for 192.168.1.128 in the config you have shown

Alex.
