Zorluk: KolayIPv6 Static Routing

A network administrator needs to configure an IPv6 static route on a Cisco IOS router for the destination network 2001:db8:acad:10::/642001:\text{db8}:\text{acad}:10::/64. The next-hop router's link-local IPv6 address is fe80::1\text{fe80}::1, and the local exit interface is GigabitEthernet0/0/1. Which Cisco IOS command correctly configures this static route?

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

Cevap

The command 'ipv6 route 2001:db8:acad:10::/64 GigabitEthernet0/0/1 fe80::1' correctly configures the static route.
When pointing an IPv6 static route to a link-local next-hop address, Cisco IOS requires both the outbound exit interface and the next-hop IPv6 address to be specified. The syntax 'ipv6 route <destination-prefix> <exit-interface> <link-local-address>' satisfies this requirement.

Adım Adım Çözüm

1
Identify the destination prefix and mask
The target network is 2001:db8:acad:10::/64.
Static routes in Cisco IOS require the destination network prefix first.
2
Evaluate the requirements for using a link-local next-hop address
Link-local addresses (fe80::/10) are ambiguous because they exist on every interface.
Cisco IOS requires specifying the exit interface along with the link-local next-hop address.
3
Construct the exact Cisco IOS IPv6 static route command syntax
ipv6 route 2001:db8:acad:10::/64 GigabitEthernet0/0/1 fe80::1
The correct format is 'ipv6 route <prefix/length> <exit-interface> <next-hop-address>'.
