As I understand it, if you use the icanreach statement with mac-exclusive,
remote peers will only send traffic destined for mac d5b3.f748.2c6a. There
will be no broadcasts. All remote peers learn your "exclusively local mac"
during the initial capabilities exchange. I don't think broadcast are ever
sent to a peer using "icanreach mac-exclusive". There would me no need.
Further, I think when you use icanreach statement your defining static
resources for the peer, which says to me no broadcast or explorer frames...
"Static Resources Capabilities Exchange
To reduce explorer traffic destined for this peer, the peer can send other
peers a list of resources for which it has information (icanreach) or does
not have information (icannotreach). This information is exchanged as part
of a capabilities exchange.To configure static resources that will be
exchanged as part of a capabilities exchange, use one of the following
commands in global configuration mode, as needed:"
