6. IPv6 Configuration - metrafonic/Cisco-Cheatsheet GitHub Wiki

Enabling IPv6

Initialize IPv6

# conf t
(config)# ipv6 unicast-routing

Configure an andress on an interface

(config)# interface [interface]
(config-if)# ipv6 address [ipv6 prefix]/[prefix length] eui-64
(config-if)# ipv6 address [link-local] link-local //not required
(config-if)# no shutdown
(config-if)# exit

Note, the ipv6 prefix will look like a netid will usually end in 0, the wui-64 command allocates the unique portion of the computer to the address. This in a whole will be the same as witing
Example:

(config-if)# ipv6 address 2001:DB8:ACAD:A::/64 eui-64

IPv6 Routing:

Static Route

(config)# ipv6 route [ipv6 prefix]/[prefix length] [next hop ipv6 address]

Default IPv6 static route

(config)# ipv6 route ::/0 [interface]

EIGRP Dynamic Routing

Enable ipv6 routing:

(config)# ipv6 unicast-routing

Start eigpr protocol

(config)# ipv6 router eigrp [AS-number]

Configure EIGRP for a 32-bit address for the router ID.

(config-rtr)# eigrp router-id [32 bit ip id] //feks 1.1.1.1

Enable:

(configure-rtr)# no shutdown
