Nokia manual Managing M1112, Configuring static and dynamic routing

Managing M1112

Automatically generated address ranges use LAN/VBRIDGE IP address as gateway and DNS server addresses. If one address range is defined, then automatic binding will be disabled. If optional address range 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 to LAN/VBRIDGE interfaces. In such cases, the DNS proxy forwards the DNS request to statically configured DNS servers or to DNS servers learned dynamically vie PPP/IPCP.

The following commands are used to configure DHCP and DNS settings:

M1112(conf-common)#dhcp? usage: dhcp mode

dhcp address dhcp gateway dhcp dns

dhcp lease-time dhcp domain-name

M1112(conf-common)#dhcp mode server ; this enables DHCP server

Normally, there is no need to configure the DNS addresses. If the service provider does not support automatic DNS address allocation, the DNS servers can be configured as shown by the following example:

M1112(conf-common)# dns address primary 1.2.3.4

M1112(conf-common)# dns address secondary 1.2.3.5

M1112(conf-common)#

5.2.2Configuring static and dynamic routing

Routing entries in the routing table are needed in order to forward the IP packets to the correct interface. M1112 has both static and dynamic routes. Static routes are configured manually and dynamic routes are learned automatically using RIP v1 and RIP v2 protocols. The following 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 0.0.0.0
