Zorluk: KolayIPv6 Static Routing

A network administrator needs to configure a static route on a Cisco router to reach destination network 2001:DB8:ABCD:10::/642001:\text{DB8}:\text{ABCD}:10::/64. The adjacent router's link-local address is FE80::2:1\text{FE80}::2:1 and the local outbound interface is GigabitEthernet0/0. Which Cisco IOS command correctly configures this IPv6 static route?

  1. ipv6 route 2001:DB8:ABCD:10::/64 GigabitEthernet0/0 FE80::2:1Cevap
  2. B
    ipv6 route 2001:DB8:ABCD:10::/64 FE80::2:1
  3. C
    ipv6 route 2001:DB8:ABCD:10::/64 GigabitEthernet0/0 FE80::FFFE:2:1
  4. D
    ipv6 route 2001:DB8:ABCD:10::/64 FE80::2:1 GigabitEthernet0/0

Cevap

The command 'ipv6 route 2001:DB8:ABCD:10::/64 GigabitEthernet0/0 FE80::2:1' correctly configures the static route.
When configuring an IPv6 static route using a link-local next-hop address, Cisco IOS requires specifying the local exit interface because link-local addresses are ambiguous and exist on every interface. The correct syntax specifies the exit interface followed by the link-local address.

Adım Adım Çözüm

1
Identify destination prefix and next-hop type
Destination prefix is 2001:DB8:ABCD:10::/642001:\text{DB8}:\text{ABCD}:10::/64, and next-hop is link-local FE80::2:1\text{FE80}::2:1.
Link-local addresses are non-routable outside the local link segment.
2
Apply Cisco IOS fully specified static route rule
Because link-local addresses are ambiguous across multiple interfaces, the exit interface GigabitEthernet0/0 must be included before the next-hop address.
Cisco IOS requires syntax: `ipv6 route <prefix/mask> <exit-interface> <next-hop-address>` when using link-local addresses.
