Subject: 2 IP's on 1 LAN
Keywords: TCP-IP Vitalink MAC-Bridge Ethernet
The need to have 2 logically separate IP networks on a single
datalink (specifically, an Ethernet LAN) for administrative reasons
has arisen.
[Examples:
a) Some nodes on a LAN have officially assigned IP addresses
because they sometimes interoperate with another network. To
conserve IP addresses, other nodes on the same LAN are assigned
IP addresses from a separate address space.
b) Two networks which are geographically separated, and which have
been administered separately, are now being connected by a
Vitalink datalink-level MAC-bridge.]
Based on experience with similar situations, is the best course of
action to:
1) Modify the IP routing algorithm in each node to understand the
notion of a "direct" route.
2) Reassign IP addresses so that all nodes have the same IP network
number.
3) Install separate devices which act as fake gateways.
4) Other
