Could you elaborate on the issues?  I've posted
a list of MLPPP bugs that have been fixed in
the last 6 months for the 75xx with dMLPPP and
if you are not running code that has those fixes
you surely will have some problems.

a) You don't have an ip address on the 36xx so any pings to/from
it will no work
b) On the 75xx side it's important if you have a BVI to interface
   the bridge to the L3 side of the router.
   I would need to see the 75xx configuration.

I don't know what you are trying to do here but I highly do
NOT recommend you do this because the bridging code for something
like this is performance wise would be horrible.
