they are connected with cross over cable on fa0/1  on both routers
on RT A int is Up/up . ip is 192.168.10.10
TR B int is up/up ip is 192.168.10.11

but from RT A cannot ping RT B

do i need a default route ? i need to be able to ping from A to B ( vendor's router)

any ideas ?

Are there any access lists perhaps blocking pings?

Hi
What is the model and company ?
Many default config of routeur block ICMP-ping. So make sure you have enable this fonction.
Just in case, be sure to desactivate DHCP on 1 of them !!

Hi,

As jrobillard and craigbeck said please post up the config.

While your doing that check and make sure the cable is working ok. Sometimes you will see a link light beside the FastEthernet ports. Can you please check and see if you have L2 connectivity by checking the light beside the cable.

To answer your question though, no, you don't need any routers. If there is a link between the devices, it is directly connected and a route is automatically inserted into your routing table.

Post your configs!
