Introduction
For example, in Figure 1-8, LANs B, C, and D are bridged to
backbone LAN A. A packet originating from LAN C destined to
the host group member on LAN B will traverse LANs C and A but
not LAN D. Similarly, an IP multicast packet destined to the group
member on LAN B that originated on that LAN will not be
forwarded to the other LANS.
Figure 1-8. Bridged LAN With One Host Group Member
In Figure 1-9, a member on LAN C joins the host group. In this
case, IP multicast packets to all host group members on LANs B
and C will again traverse LANs A, B, and C, but not LAN D.
