The IP router has a 10BaseT interface (Ethernet at 10 Mbit/s via Cat5 cable).
When using IP routers, the following rules must be observed:
• With an IP router used as an area coupler (IP Ac) no other IP routers may be
installed below the IP Ac in the topology.
• With an IP router used as a line coupler (IP Lc) no other IP routers may be
installed above the IP Lc in the topology.
When IP routers are used for coupling to an IP network, the following points must
be discussed with the IP network administrator:
• Automatic address assignment via DHCP (see section 8.3)
or
• Manual IP address assignment (see section 8.3)
and also:
IP routing, multicast addresses
IP subnet mask
IP standard gateway
