Configuration and Operation Example.
MAC Encapsulated Routing allows IP packets to be carried as
bridged frames. The RFC1483 link protocol with MER is a
multiprotocol encapsulation method over ATM. While the true
IEEE802.1D Transparent Bridge is a hardware component of the
STWireless , for MER, the encapsulation method is implemented
by software.
In the PCs, IP packets are encapsulated in MAC frames, according
their destination:
"
For local networking, the destination MAC address is the one
of the destination device, e.g. another PC
"
For nonĆlocal traffic, the destination MAC address is that of
the STWireless
"
In both cases, the source MAC address, is the MAC address of
the source device, e.g. your PC.
All MAC frames arrive via the Ethernet segment in the
STWireless . It decapsulates the MAC frames and routes the IP
packets, according their destination.
