Zorluk: KolayIPv6 Static Routing

A network administrator needs to configure an IPv6 static route on a Cisco IOS router to reach the destination prefix 2001:db8:1:10::/642001:\text{db8}:1:10::/64. Which of the following commands represent valid IPv6 static route configurations? (Select TWO.)

  1. ipv6 route 2001:db8:1:10::/64 2001:db8:1:1::2Cevap
  2. ipv6 route 2001:db8:1:10::/64 GigabitEthernet0/0 fe80::1Cevap
  3. C
    ipv6 route 2001:db8:1:10::/64 fe80::1
  4. D
    ip route 2001:db8:1:10::/64 2001:db8:1:1::2

Cevap

The valid IPv6 static route commands are 'ipv6 route 2001:db8:1:10::/64 2001:db8:1:1::2' (directly specifying a global unicast next-hop) and 'ipv6 route 2001:db8:1:10::/64 GigabitEthernet0/0 fe80::1' (fully specifying both the exit interface and the link-local next-hop address).
Valid Cisco IOS IPv6 static route configurations require the 'ipv6 route' keyword followed by the destination prefix. The next hop may be specified either as a global unicast IPv6 address directly, or as a link-local IPv6 address provided that the local exit interface is also explicitly specified.

Adım Adım Çözüm

1
Verify correct command prefix keyword for IPv6 static routing
Cisco IOS requires 'ipv6 route' rather than 'ip route'.
The 'ip route' command is strictly used for configuring IPv4 static routes.
2
Evaluate next-hop syntax with global unicast addresses
A global unicast IPv6 address can be configured directly as a next hop without specifying an exit interface.
Global unicast addresses are globally unique and routable across network interfaces.
3
Evaluate next-hop syntax with link-local addresses
A link-local next-hop address (fe80::/10) requires specifying the local exit interface alongside the address.
Link-local addresses are only valid on their specific local link, making the command ambiguous to the router if the exit interface is omitted.
