Does IOS demand GRE elaboration task to the vpn acceleration card, if present in 17xx, 26xx, 36xx routers ?

Thanks

Re: vpn module and GRE

Hi,

Regular IP Packet gets encasulated inside GRE header before IPSec, so I dont believe it does.

Thx

Afaq, so GRE encapsulation is carried out by the main router processor and then encrypted by the vpn module ?

(Where could I get GRE tunnelling performance ?)

Thank you again

Renato
