MTU Problem

Hi team.

I´m having some problems in a Bridging network. I have a Cisco 7513 then ATM cloud and then a Catalyst 2924 whit a STM-1 ATM, doing binding between PVC and VLAN.

The problem is i can´t do ping greater than 1484 b.

In the 7513 i have already configured RBE, whit the ip in the Loopback interface ( IP unnumbered ). And the MTU is configured in 1500 in the subint ATM

I did some test´s and the router is doing something very strange.

I had configured a PVC whit RBE and it didn´t work, but if i create a new interface and paste the pvc in this inteface works fine. If i delete the PVC and create again it didn´t work. And the again the same create a new interface and works again etc...

I think is a Bug but.........

I hear any comments.

Thks all.

Re: MTU Problem

Certainly appears to be bug related.

Insert your software version into this tool and check your results. If you are unsuccessful contact the Technical Assistance Center; though expect a request for code upgrade early in the process.

Re: MTU Problem

Remove "mtu 1500" from the ATM interface and try adding " ip mtu 1500 " and see whether it works.
