Study Notes

Module Overview

Module Title: IP Static Routing
Objectives include configuring both IPv4 and IPv6 static routes, default static routes, floating static routes, and static host routes.

Types of Static Routes

Static routes can be used alongside dynamic routing protocols in networks.
Types of static routes for IPv4 and IPv6 include:
- Standard static route
- Default static route
- Floating static route
- Summary static route
Configuration commands: ip route for IPv4 and ipv6 route for IPv6.

Next-Hop Options

Static routes can specify the next hop via an IP address, exit interface, or both.

IPv6 Routing Tables

Each router only maintains entries for directly connected networks.
IPv6 routes can include link-local addresses, requiring fully specified routes in certain configurations.

Configuring IP Static Routes

IPv6 Directly Connected Static Route:
- Use the exit interface to configure directly connected static routes; recommended to use a next-hop address.
IPv4 Fully Specified Static Route:
- Specify both exit interface and next-hop IP address, particularly in multi-access interfaces. Using next-hop address is mandatory when the exit interface is not defined.
IPv6 Fully Specified Static Route:
- Similar to IPv4, both exit interface and next-hop IPv6 address must be mentioned, especially for link-local addresses.

Default Static Routes

Default routes are characterized by the prefix ::/0 for IPv6 and 0.0.0.0 0.0.0.0 for IPv4.
Use a default static route to match all packets when no other specific routes are available.

Floating Static Routes

Designed as backup paths for primary routes (static or dynamic).
Configured with a higher administrative distance than primary routes, only activated if the primary route fails.
Default administrative distance for static routes is 1, making them preferred unless configured otherwise.

Commands for Floating Static Routes

Sample commands to set up default and floating static routes are provided for both IPv4 and IPv6.

Testing Floating Static Routes

When primary routes go down (e.g. R2 serial interfaces are shut), the floating route takes over.

Static Host Routes

Defined as routes that direct traffic to a specific host, using a 32-bit mask for IPv4 or a 128-bit mask for IPv6.
