Question

Difficulty: EasyIPv6 Static Routing

What prefix and prefix length parameter completes the Cisco IOS command to configure a default IPv6 static route pointing to next-hop address $2001:

\text{db8}:1::2$?

Answer:Router(config)# ipv6 route 【::/0】 2001:db8:1::2

Answer

The correct notation to represent a default route in IPv6 static routing is ::/0.
In IPv6 static routing, ::/0 is the prefix notation for a default route, serving the same function as 0.0.0.0/0 in IPv4.

Step-by-Step Solution

1
Identify the network prefix used to match all possible IPv6 destinations.
The default IPv6 route prefix is written as ::/0.
In IPv6 addressing, :: represents all zeros, and /0 indicates a prefix length of zero bits, matching any destination address.
2
Substitute the default prefix into the Cisco IOS IPv6 static routing command syntax.
The completed command is 'ipv6 route ::/0 2001:db8:1::2'.
The standard command syntax requires 'ipv6 route <destination-prefix/prefix-length> <next-hop-address>'.
