3 - Subnet Mask
The Subnet Mask option displays the subnet mask defined by the subnet mask size in option 2.
* Display only. This mask is set when the mask size entry is defined for the first time and may not be changed here; to
make a change, the entry must be removed from the secondary address table and re-entered.
4 - Routing Protocol
The Routing Protocol option defines the type of IP routing protocol to be used on this secondary network.
When the routing protocol is defined as none, the P1700 will NOT participate in the exchange of RIP messages for this
secondary network with the other networks. Routing on this secondary network is accomplished by using static routes.
All routes within this secondary network must be manually entered as the static routes. Host devices and other routers
on this network must be statically configured (they will not receive RIP messages). Routes with next hops on this
network must be statically configured on this router. In addition to the static routes entered, this router will use routing
information learned from other interfaces and networks
When the routing protocol is defined as rip1, the P1700 will use RIP1 IP protocol for this secondary network. All
routing information will be sent and received via broadcast RIP packets.
When the routing protocol is defined as rip1_compatible, the P1700 will use RIP2 IP protocol in broadcast mode for
this secondary network. All routing information will be sent via broadcast RIP2 packets. Routing information may be
received as broadcast RIP1, broadcast RIP2, or multicast RIP2.
When the routing protocol is defined as rip2, the P1700 will use RIP2 IP protocol for this secondary network. All
routing information will be sent via multicast RIP2 packets. Routing information may be received as broadcast RIP2 or
multicast RIP2.
Networks on this router do not need to use the same IP routing protocols. For example, one secondary network may be
set as RIP_compatible to learn and advertise changes to the network, while another may be set to none and must use
static routes.
Default: [rip1_compatible]
Choices: none, rip1, rip1_compatible, rip2
5 - RIP Mode
The RIP Mode option defines how this P1700 will participate in RIP IP routing message exchange for this subnet.
When the RIP mode is set to both, the P1700 will send and receive RIP routing messages.
When the RIP mode is set to send_only, the P1700 will only send RIP routing messages.
When the RIP mode is set to receive_only, the P1700 will only receive RIP routing messages.
Default: [both]
Choices: both, send_only, receive_only
