[nsp] alternative to "l2tp security crypto-profile"

[Victor Sudakov]

Colleagues, 

If vpdn traffic between LAC and LNS needs to be encrypted, I wonder if
it is possible to use conventional transport mode IPSec (with crypto
acls) between the two, instead of using the "l2tp security crypto-profile" 
mechanism as specified in 
http://www.cisco.com/univercd/cc/td/doc/product/software/ios122/122newft/122t/122t4/ftl2tsec.htm

I do not have 12.2T and do not wish to migrate to it or to 12.3 yet.

Thanks in advance for any input.
