No, that's an example of a poorly designed protocol implementation. One ought to be able to specify an arbitrary router id for OSPF (heh - even Bay routers can do that :) rather that relying on such an odd algorithm. I was so surprised by this that I just had to go look it up: <http://www.cisco.com/univercd/data/doc/software/11_2/cnp1/5ciprout.htm#REF38888> The equivalent Bay reference: <http://support.baynetworks.com/Library/tpubs/content/114065A/J_55.HTM#HEADING55-6> [A copy of the headers and the PGP signature follow.] Date: Tue, 11 Feb 1997 14:23:20 -0600 From: "Jeffrey C.
