1921 Router

[ciscojoe837]

What's the SEC license function on a 1921 router vs. not getting it with the SEC license.  That is Cisco1921/K9 vs. Cisco1921-SEC/K9.  Why would I choose one over the other?

The first one runs standard ip base license the 2nd is a security license which would be more advanced for your router and have more available security features

Thanks for that.

1. Would you get the non-sec if the 1921 was not going to face the Internet then?
2. I did a search and a post said that the SEC helped with VPN encryption.  So does the non-SEC not do VPN?
3. Do you know if there is a compare chart with non-sec features vs. sec features?
4. And finally, can the 1921 be used for CCNA study and would I need a serial WAN EHWIC on each (assuming I had 2 or 3 1921's).  What is a serial WAN interface and in what scenario would it be used?   Is that used for router-to-router connectivity? 

Thanks again.

1 This depends on what features your using,  ipbase will have less security features and is a more stripped down version of ios , that comes free with the router

2 you still need a license for IPsec/vpn even on the seck9 ios if your planning on doing IPsec-IPsec vpns

3 not sure about a chart

4 yes it can but gns3 is free and covers all aspects of routing for the ccna including serial interfaces which are becoming legacy, it also covers full crypto vpns , im not sure if serial interfaces even still in the ccna, I wouldn't go out and buy 1 anyway, just load up a 7200 in gns3 with advanced image and you will have everything you need to study
