Overview
This lecture covers configuring IPv6 addresses (EUI-64 and manual methods), enabling IPv6 on interfaces, setting up IPv6 static routes, and introduces RIPng for dynamic IPv6 routing.
Configuring IPv6 Addresses
- Use EUI-64 to auto-generate the interface ID by splitting the MAC address, inserting FFFE, and inverting the 7th bit.
- Enable IPv6 routing with the command
ipv6 unicast-routing.
- Assign IPv6 addresses to interfaces using
ipv6 address <prefix> eui-64.
- Link-local addresses are automatically created (prefix FE80::/10) and use EUI-64.
Configuring End Devices
- Set the default gateway of PCs to the router’s IPv6 address on the connected interface.
- Manually assign IPv6 addresses to PCs with a /64 prefix.
Enabling IPv6 on Interfaces
- Use
ipv6 enable to automatically assign a link-local address to an interface without specifying a global address.
IPv6 Static Routing
- Configure static routes with
ipv6 route <destination> <exit-interface> <next-hop>.
- Specify both exit interface and link-local next-hop for routes using link-local addresses.
- Test connectivity using ping commands.
Introduction to RIPng (IPv6 Dynamic Routing)
- RIPng is the version of RIP for IPv6 dynamic routing.
- Enable RIPng with
ipv6 router rip <process-name> (global) and ipv6 rip <process-name> enable (interface).
- In RIPng, processes are enabled directly on interfaces instead of using the
network command.
- After configuration, use
show ipv6 route and show ipv6 protocols to verify routes.
Key Terms & Definitions
- EUI-64 — Method for generating IPv6 interface IDs from MAC addresses.
- Link-local address — IPv6 address valid only within a local network segment, starting with FE80::/10.
- Static route — Manually configured route in a routing table.
- RIPng — Routing Information Protocol next generation; supports IPv6.
- Default gateway — Router address used by an end device to send traffic outside its local network.
Action Items / Next Steps
- Practice configuring IPv6 addresses using EUI-64 and manual methods.
- Enable IPv6 and configure static routes on routers.
- Read up on RIPng and try enabling it on router interfaces.
- Prepare for a deeper dive into IPv6 static routing in Day 33.
