Description After you configure the dlsw reachable command, the router sends a packet to
all the connected routers, notifying of the locally reachable MAC or SAP address.
Based on the information, these routers can decide whether to send packets to this
router without exploring.
Note that you must change the configuration in time to accommodate to changes on
the local network.
