Zorluk: OrtaIPv6 Static Routing

A network administrator is configuring static routing on router R1 to forward traffic toward network 2001:db8:3c4d:10::/64. The administrator intends to use the link-local address fe80::211:22ff:fe33:4455 of the neighboring router connected to local interface GigabitEthernet0/1. Which Cisco IOS command correctly configures this static route?

  1. ipv6 route 2001:db8:3c4d:10::/64 GigabitEthernet0/1 fe80::211:22ff:fe33:4455Cevap
  2. B
    ipv6 route 2001:db8:3c4d:10::/64 fe80::211:22ff:fe33:4455
  3. C
    ipv6 route 2001:db8:3c4d:10::/64 fe80::211:22ff:fe33:4455 GigabitEthernet0/1
  4. D
    ip route 2001:db8:3c4d:10::/64 GigabitEthernet0/1 fe80::211:22ff:fe33:4455

Cevap

The command 'ipv6 route 2001:db8:3c4d:10::/64 GigabitEthernet0/1 fe80::211:22ff:fe33:4455' correctly configures the fully specified IPv6 static route.
The statement specifying the local exit interface GigabitEthernet0/1 followed by the next-hop link-local address fe80::211:22ff:fe33:4455 complies exactly with Cisco IOS requirements for fully specified IPv6 static routes.

Adım Adım Çözüm

1
Identify the proper Cisco IOS command prefix for IPv6 routing
The command must start with 'ipv6 route' rather than 'ip route'.
Cisco IOS separates IPv4 and IPv6 static route configurations into distinct global commands.
2
Evaluate the next-hop address scope
The next-hop address 'fe80::211:22ff:fe33:4455' is a link-local IPv6 address (fe80::/10).
Link-local addresses exist on every IPv6-enabled interface, so an egress interface MUST be supplied to resolve ambiguity.
3
Verify Cisco IOS syntax parameter ordering
The syntax requires 'ipv6 route <prefix/length> <exit-interface> <link-local-address>'.
Specifying GigabitEthernet0/1 followed by fe80::211:22ff:fe33:4455 forms a valid fully specified static route.
