I am teching the simular course for the MIPT students here in Russia, and 
we choose to teach a few _overview_ courses. I myself (with my collegues) 
was developing and teaching _the basics of IP routing_ course, with the 
two main ideas:

- (1) to cover all oportunities the network engeneers have to desing 
moder networks. IT include:
- TCP/IP basics
- LAN routing protocols, such as OSPF, RIP and EGRP; and I'v tried to 
built the topics from the two parts, for example - (1a. OSPF, view for 
the beginners /plain OSPF based network, very simple, no areas, stubs etc 
etc - and it's highly recommended for all middle-size corporate networks 
- with a very simple configuration: router OSPF 1;network area;
1b. Why OSPF is not really so simple - areas, complex ropology, etc etc - 
some minimum, not more.
- special LAN protocols (very important) - HSRP, ICMP redirect, router 
discovery, Cisco Discovery Protocol;
- Internet routing - basics - why there is BGP, what is it, how it is 
used by the multihome customers; how is it used by the ISP (special topic 
- the routing in the ISP back-bone - IGP + BGP 2 level routing schema - 
the basics.
- VLAN networks - very important topics to know - include FDDI/802.10, 
ISL (!, don't forget), 802.1q, LANE (terrible!) as the trunk protocols, 
explain how the routers and switches interconnect (with the 
sub-interfaces etc etc), why 802.1q or ISL need some other hardware (more 
frame size);
- Multicast (the basics only);
- ATM etc - the basics.

I think (as the head of NOC) the network engeneer should know:
- modern networking - very well, including some vendor-based standards 
such as CISCO HDLC, ISL VLAN, some FORE and BAY's protocols;
- network troubleshooting - to have some labs;
- programming - the basics of C, C++ (not so important for the 
programming but very important for the education), PERL (!), Visual Basic 
and script programming on Windows. Network engeneers do not develop 
usially huge and java-based systems but they must be able to write 
quickly a simple CGI script or modify existing one;
- HP OV and other SNMP-based (terrible, but the only existing) monitoring 
systems, just as RMON basics.

What's _basics_? It mean don't detailed knowing of the exact commands, 
config files, etc, but knowing of the main ideas the authors realised in 
the protocol or the system - what for is (HSRP), where do we use it 
(HSRP), can it work on VLAN-ed network or not, etc etc...

And - the _troubleshooting labs_ as well - the 99% of the students could 
not found any complex failure (for example - the loss of syncronisation 
in the ATL LS-1010-based network caused a lot of interfaces fail down - 
the mister Sherlok Holms could guess the reason withouth ever knowingv 
the world _router_, but the students could not found the reason at all).

Course project will likely be design and implement a bridge, possibly including source-route and certainly including spanning tree. Early on, coverage of WAN include project with PCM and such.

Comer's graduate course has students build a router but this is probably too much for undergraduates. Instead an OSPF implementation, including all the options (especially NSSA) . A cursory introduction to sockets programming with the course focus on routing algorithms (i.e. RIP, OSPF, and BGP4).

The entire class would divide into teams with assignments that comprise various parts of the client and server portions.  The project would be a turn-based simulation game (I used to play these and have a number of appropriate games with play-by-mail options, game rule design and/or game theory is not part of the course).  While this won't teach them to be router engineers -- or developers, it should have some industry relevance.
