Problem with subinterface GSR

Hi, I Have several subinterfaces configured in GSR closing the connection L3 in some BRAS (connection point-to-point). But after everything configured with itself ping in some interfaces and other no. Did some already catch this problem, will it be that he has to do some thing with MTU?

What interface? ATM?

You are assuming we know about your network, but we don't.

You must include more details.

The interface in use is GigabitEthernet in the module SPA-5x1GE.

Check that the VLAN you are using do exist in the switches and the devices are connected to ports correctly configured.

If the VLANs were correct, and the devices were correct, ping and everything else would work.

Since it doesn't work, we must conclude something is not correctly configured.
