Network Topology Example
Figure 1shows many of the connectivity options provided by the BN function. In
general, you can get from any network to any other network except that NetF can
only reach network NetE and NetE is the only network that can reach NetF.
Note: Solid lines represent intersubnetwork TGs.
In this figure:
vNetid subnetwork NetA has been divided into topology subnetworks. The
left-most topology subnetwork contains BNa1 which is connected across an
intersubnetwork TG to BNa2 in the right topology subnetwork. The netid of both
BNa1 and BNa2 is NetA.
vBNa1 is non-native to all the other extended border nodes, including NetA2.
vBNa2, BNa3 and BNa4 are all native to the right topology subnetwork of NETA,
and non-native to the other networks, including the subnetwork containing BNa1.
vA BN can interconnect multiple networks as BNa4 connects topology subnetwork
of NetA to both NetB and NetD.
vMultiple links can connect two networks as the right topology subnetwork of NetA
and NetB are connected by both BNa3/BNb1 and BNa4/BNb2.
