# On Router C, create an IPsec transform set named protrf1, and set the encapsulation mode to 
transport mode, the security protocol to ESP, the encryption algorithm to 3DES, and authentication 
algorithm to MD5. Create an IPsec profile named profile001, specify the manual mode for it, 
reference IPsec transform set protrf1, and set the SPIs of the inbound and outbound SAs to 256 and 
the keys for the inbound and outbound SAs using ESP to abc.
