Managing M1112 Copyright Nokia Networks OyC33907001SE_00 5-5Automatically generated address ranges use LAN/VBRIDGE IPaddress as gateway and DNS server addresses. If one address range isdefined, then automatic binding will be disabled. If optional addressrange parameters like gateway or DNS addresses are not defined,LAN/VBRIDGE IP addresses are used as in automatic binding.Typically, when DHCP is used, the advertised DSN addresses point toLAN/VBRIDGE interfaces. In such cases, the DNS proxy forwardsthe DNS request to statically configured DNS servers or to DNSservers learned dynamically vie PPP/IPCP.The following commands are used to configure DHCP and DNSsettings:M1112(conf-common)#dhcp?usage: dhcp modedhcp addressdhcp gatewaydhcp dnsdhcp lease-timedhcp domain-nameM1112(conf-common)#dhcp mode server ; this enablesDHCP serverNormally, there is no need to configure the DNS addresses. If theservice provider does not support automatic DNS address allocation,the DNS servers can be configured as shown by the followingexample:M1112(conf-common)# dns address primary 1.2.3.4M1112(conf-common)# dns address secondary 1.2.3.5M1112(conf-common)#5.2.2 Configuring static and dynamic routingRouting entries in the routing table are needed in order to forward theIP packets to the correct interface. M1112 has both static and dynamicroutes. Static routes are configured manually and dynamic routes arelearned automatically using RIP v1 and RIP v2 protocols. Thefollowing examples show how to configure static routes to M1112.Default gateway for an interface that learns the next hop automatically:M1112(conf-common)# ip route 0.0.0.0 0.0.0.0 0.0.0.0vcc1
