Dynamic routing using the Routing Information Protocol (RIP) is an Interior
Gateway Protocol (IGP) that is common in LANs. With RIP this router can exchange
routing information with other supported routers in the LAN and allow for dynamic
adjustment of routing tables in order to adapt to modifications in the LAN without
interrupting traffic flow.
The RIP direction will define how this router sends and receives RIP packets.
Choose between:
ï‚· Both: The router both broadcasts its routing table and also processes RIP
information received from other routers. This is the recommended setting in
order to fully utilize RIP capabilities.
ï‚· Out Only: The router broadcasts its routing table periodically but does not
accept RIP information from other routers.
ï‚· In Only: The router accepts RIP information from other routers, but does not
broadcast its routing table.
ï‚· None: The router neither broadcasts its route table nor does it accept any
RIP packets from other routers. This effectively disables RIP.
ï‚· The RIP version is dependent on the RIP support of other routing
devices in the LAN.
ï‚· Disabled: This is the setting when RIP is disabled.
ï‚· RIP-1 is a class-based routing version that does not include subnet
information. This is the most commonly supported version.
ï‚· RIP-2 includes all the functionality of RIPv1 plus it supports subnet
information. Though the data is sent in RIP-2 format for both RIP-2B and
RIP-2M, the mode in which packets are sent is different. RIP-2B broadcasts
data in the entire subnet while RIP-2M sends data to multicast addresses.
If RIP-2B or RIP-2M is the selected version, authentication between this router and
other routers (configured with the same RIP version) is required. MD5
authentication is used in a first/second key exchange process. The authentication
key validity lifetimes are configurable to ensure that the routing information
exchange is with current and supported routers detected on the LAN.
3.5.3 Static Routing
Advanced > Routing > Static Routing
Advanced > IPv6 > IPv6 Static Routing
Manually adding static routes to this device allows you to define the path selection
of traffic from one interface to another. There is no communication between this
router and other devices to account for changes in the path; once configured the
static route will be active and effective until the network changes.
