Configuring Routing (RIPng)
RIP Next Generation (RIPng) is a routing protocol based on the distance vector
(D-V) algorithm. RIPng uses UDP packets to exchange routing information through
port 521.
RIPng uses a hop count to measure the distance to a destination. The hop count is
referred to as metric, or cost. The hop count from a router to a directly-connected
network is 0. The hop count between two directly-connected routers is 1. When
the hop count is greater than or equal to 16, the destination network or host is
unreachable.
By default, the routing update is sent every 30 seconds. If the router receives no
routing updates from a neighbor after 180 seconds, the routes learned from the
neighbor are considered as unreachable. After another 240 seconds, if no routing
update is received, the router removes these routes from the routing table.
On the device, RIPng is disabled by default.
Prefix Length Number of prefix bits in the IPv6 address that define
the destination subnet.
Gateway IPv6 address of the gateway through which the
destination host or network can be reached.
Interface Interface for the route: LAN, WAN, or 6to4.
Metric Priority of the route. Choose a value between 2 and 15.
If multiple routes to the same destination exist, the
route with the lowest metric is used.
Active Check to make the route active. When you add a route
in an inactive state, it is listed in the routing table, but is
not used by the device.
Entering an inactive route is useful if the route is not
available when you add the route. When the network
becomes available, you can enable the route.
