Networking Configuring IPv6 Addressing 2 STEP 3 Enter the following information: • Route Name: Enter the name of the route, for identification and management purposes. • Active: Check this box to enable the route, or uncheck this box to disable the route. When a route is added in inactive state, it is listed in the table, but will not be used for routing. This feature allows you to configure the routes even before the destination network is ready to receive traffic. Enable the routes when ready. • IPv6 Destination: Enter the IPv6 address of the destination host or network for this route. • IPv6 Prefix Length: Enter the number of prefix bits in the IPv6 address to define the subnet. • Interface: Choose the physical network interface for this route (Dedicated WAN, Optional WAN, DMZ or LAN), through which this route is accessible. • Gateway IP Address: Enter the IP Address of the gateway through which the destination host or network can be reached. • Metric: Specify the priority of this route by entering a value between 2 and 15. If multiple routes to the same destination exist, the security appliance chooses route with the lowest metric. STEP 4 Click Apply to save your settings. Routing (RIPng) RIPng (Routing Information Protocol - next generation, RFC 2080) is a routing protocol that uses UDP packets to exchange routing information through port 521. The distance to a destination is measured by the hop count, as follows: • 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 security appliance 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 security appliance remove these routes from the routing table. Cisco SA500 Series Security Appliances Administration Guide 84

Routing (RIPng)
RIPng (Routing Information Protocol - next generation, RFC 2080) is a routing
protocol that uses UDP packets to exchange routing information through port 521.
The distance to a destination is measured by the hop count, as follows:
•
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 security appliance
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 security appliance remove these routes from the
routing table.
