Overview of IPv6 Static Routing
Static routes can be used to specify
desired routes, backup routes, or routes of last resort. Static routing can help provide
load balancing.
Static routes are manually configured entries in
the IPv6 routing table. In setting up static routes, you can specify several types of
destinations:
- Destination network, using an IP
address and prefix length
- Default network route
- Next hop router
- VRF for the next hop
- Ethernet interface, typically used for
directly attached destination networks
- Port-channel interface
- Virtual interface
- Null interface
You can influence the preference a route is
given:
- Configure a route metric higher than
the default metric
- Give the route an administrative
distance
Static routes can be configured to serve as any of the following:
- Default routes
- Primary routes
- Backup routes
- Null routes for intentionally dropping traffic when the desired connection fails
- Alternative routes to the same destination to help
load balance traffic
