Study Notes

Configure Static Host Routes

Static host routes are manually configured to direct traffic to specific destination devices.
For IPv4, use the destination IP address with a 255.255.255.255 (/32) mask; for IPv6, use a /128 prefix length.
When configuring IPv6 static routes with a link-local next-hop, specify both the interface type and number.
Automatically installed host routes are created when an IP address is configured on a router.
Local host routes are marked with an "L" in the routing table and enhance packet processing efficiency.

Verify Static Host Routes

Use show ip route and show ipv6 route to confirm that both IPv4 and IPv6 static host routes are active.
Additional verification commands include show ip route static, show running-config | section ip route, and ping or traceroute.

Static and Default Static Routes

A default static route matches all packets, ensuring they are directed appropriately in absence of a more specific route.
Static routes can significantly improve routing efficiency by directing traffic based on specific needs.

IPv4 and IPv6 Routing Tables

Routing tables for IPv4 and IPv6 contain entries for directly connected networks and associated local addresses.
Notable routing table entries include connected routes ("C") and local routes ("L").
Ensure routes are correctly identified and troubleshoot connectivity issues through ping tests.

New Terms and Commands

Familiarity with routing terminology is crucial:
- Static Route: A pre-defined route manually set in the routing table.
- Default Static Route: A fallback route for unknown destinations.
- Next-Hop Route: Specifies the next device to which a packet is forwarded.
- Fully Specified Static Route: Includes both the link-local address and exit interface.

IPv6 Specifics

Fully specified static routes are necessary for IPv6 link-local addresses due to their unique scope per link.
Link-local addresses are not included in the routing table, necessitating the inclusion of exit interfaces in route configurations.

Best Practices

Regularly verify static routes and configurations to ensure accurate and efficient network performance.
Maintain proper documentation of static routes to facilitate easy troubleshooting and network management.
