Hi there,
I got a serial interface as a member of bridge group 1. An IRB bridge with interface bvi 1 has been created. IPSec tunnel is supposed to between this serial interface and remote site. A crypto map has been configured under BVI 1 interface. However, we find that packets are decrypted in this router, but no packet is being encrypted from a command "show crypto engine connection active", there is no increase in Encrypt column.
May I ask is it feasible to implement crypto map in BVI interface. And is there any alternative for this case?
many thanks
David

Try applying the crypto mapo to both the BVI and the physical serial interface. Other than that, can you post your config (xxxx out your passwords, etc) for us to have a look at.

Hi,
I have tried to apply crypto in both serial 0/0.1 and and BVI interface, but still fail.
The config is as below for your reference.

Reapply the crypto map to the serial interface also, then on both the serial and the BVI do "no ip route-cache" and see if that works. There's lots of bugs in 12.1 code with fast switching and IPSec and virtual interfaces.
