DLSw+ with Ethernet Redundancy Configuration Example
Figure 144 shows that Router A, Router B, and Router C advertise their presence on the Ethernet via
their Ethernet interfaces to the multicast MAC address 9999.9999.9999. Because Router B is the master
router, it keeps a database of all circuits handled within the domain and grants or denies permission for
new circuit requests for Router A and Router C. There is no special configuration required for the end
stations or for the remote peer. Only the DLSw+ devices on the LAN need the extra configuration.
Master Router B waits 1.5 seconds after it receives the first IWANTIT primitive before assigning the new
SNA circuit to one of its ethernet redundancy peers because of the dlsw transparent timers sna 1500
command.
