Configuring IP Services
2-26
All BFE hosts are members of Class A IP networks. The format of a BFE IP
address is as follows:
nnnnnnnn.Zpppdddd.ddddddbb.bbbbbbbb
where:
BFE supports only physical addressing. It does not support either logical
addresses or subaddresses.
Each configuration in Table 2-1 and Table 2-2 is expressed as
source device ➔ medium ➔ destination device
For example:
Bay ➔ Eth ➔ Bay
where the source device is a Bay Networks router, the medium is Ethernet, and the
destination device is a Bay Networks router.
A more complex configuration is expressed as
source device ➔ medium ➔ intermediate device ➔ medium ➔ destination device
For example:
Bay ➔ Token ➔ Bay ➔ Token ➔ ES
where the source device is a Bay Networks router, the first medium is a Token
Ring network, the intermediate device is a Bay Networks router, the second
medium is another FDDI, and the destination device is an endstation from another
vendor.
nnnnnnnn
identifies the network ID in bits
Z
is zero
ppp
is the port ID in bits
dddd.dddddd
is the domain ID in bits
bb.bbbbbbbb
is the BFE ID in bits
