NN46110-500
Multinetting is supported on the following Nortel VPN Routers: Nortel VPN
Router 1100/1010/1050 and 600, 1700, 1600/1500, 2700, 2600/2500, 4500/4600
and 5000. The multinetting feature is interoperable with Nortel VPN Router
100-400, BayRS, P8000 (8100, 8600, 1200) and Baystack LAN/Campus
switches, and Cisco IOS routers.
Figure 7 on page 41 represents a legacy system consisting of two class B IP
subnets, 10.1.0.0/16 and 11.1.0.0/16. Both subnets are connected to one physical
LAN port on Nortel VPN Router. Nortel VPN Router sends packets to and
receives packets from a host on either of these networks using the same physical
port.
Authentication Pro-
tocols (RADIUS)
Support for interface authentication at the interface
level, as specified under the Primary address on the
interface. The same rules apply to all other secondary
addresses on the interface.
VRRP Supported when Primary address is used as the VRRP
master/backup address. VRRP not applicable on sec-
ondary addresses.
Other routing (RIP,
OSPF, Static)
Routing protocols are configured separately on each
address (subnet) on a multinetted interface.
DHCP server Internal DHCP Server assumes address requests are for
the subnet of the primary interface. DHCP Relay func-
tion from a multinetted interface forwards the interface
address as the primary address in relaying a DHCP
request.
Management Proto-
cols (HTTP; HTTPS;
SNMP; FTP; Telnet;
Identification; CRL
Retrieval; CMP)
Primary address on the interface is the management
address for the Nortel VPN Router Device. Secondary
addresses cannot be the management address.
