ACE SM in a bridge mode

[axfalk]

We're architecting a pair of the ACE SM's and trying to better understand the upside/downside of configuring them in the bridged vs. a routed mode. Also, undr what circumstances  the bridge mode would be superior to the routing mode?

Thanks..

If running in bridged mode you are free to use any routing protocol your routers support. The ACE will not interfere with the routing.

But beware, the ACE bridges only connected networks. Only version A2 3.0 has secondary address support.

Thanks for your response. Does the return traffic hit the MSFC first, since it's where the default gateway is and then goes to the ACE to get bridged or traverse the ACE on the way to the default gateway?

thanks again.
