[c-nsp] Monitoring L3 link status

[Brad Henshaw]

This is another possible solution. From memory you can select the source
interface for RTR/SAA probes.
3750ME doesn't support BFD.

For probing / monitoring, the ip sla / rtr functionality from B-D and
C-E would be the normal way (assuming D and E answer pings). It doesn't
run continuously and getting the results back via SNMP can be a pain,
but it's a reasonable solution.

For actually detecting failures on the link, something like BFD or
802.3ah would be the correct solution. I don't know if the 3750ME
supports either, and the latter is quite new and still therefore raw.
