[c-nsp] 7200 T1 Aggregator - ~30-40 LSA events/sec. Normal?

[Matt Stockdale]

Hmm. It looks like when I took a tcpdump sample earlier, I managed to
grab the LSA's for the static route during their normal retransmit. It
looks like the ongoing flood of LSA's is coming from somewhere else, and
being passed along. I'll keep investigating.
