Direct connect a 1721 and 1760

Level 1

Hi,

I just purchased one of each of the above, both with 1ea WIC 1DSU-T1, and would like to connect them directly to each other in a lab scenario.  Do I need to have an RJ48 cable or will an RJ45 work?  I have them connected now, but they are not seeing each other. They are connected via S0 on the 1721 and S1/0 on the 1760.


This is the scenario I am using:

On 1721:

loopback 192.168.1.1/24

Fa0 172.17.1.1/24

S0 10.10.3.1/24

On 1760:

Loopback 192.168.2.1/24

Fa0/0 172.18.1.1/24

S1/0 10.10.4.1/24

On both:

router ospf 1

network 0.0.0.0 255.255.255.255 area 0

If I missed something, please let me know, or point me to where I can get some more info.

Thanks

I just want to add that the serial interfaces on both routers needs to be configured with ip addresses in same subnet.

I see that 1721 has 10.10.3.1/24 and 1760 has 10.10.4.1/24. Choose one of subnets and use, but not both.

Hope this helps

Eugen
