Global Routing Configuration
– 872 –
◆ If an administrative distance is defined for a static route, and the same
destination can be reached through a dynamic route at a lower administration
distance, then the dynamic route will be used.
◆ The default distance of 1 will take precedence over any other type of route,
except for local routes.
◆ If both static and dynamic paths have the same lowest cost, the first route
stored in the routing table, either statically configured or dynamically learned
via a routing protocol, will be used.
Example
This example forwards all traffic for subnet 2001::/64 to the next hop router
2001:DB8:2222:7272::254, using the default metric of 1.
Console(config)#ipv6 route 2001::/64 2001:DB8:2222:7272::254
Console(config)#

id] | local | static]
ipv6-address - A full IPv6 address including the network prefix and host
address bits.
prefix-length - A decimal value indicating how many contiguous bits (from
the left) of the address comprise the prefix (i.e., the network portion of the
address).

◆ The FIB contains information required to forward IP traffic. It contains the
interface identifier and next hop information for each reachable destination
network prefix based on the IP routing table. When routing or topology
