Zorluk: OrtaIPv6 Static Routing

An engineer is configuring a static route on a Cisco router to reach the destination subnet 2001:db8:a100:12::/642001:\text{db8}:\text{a100}:12::/64 using the neighbor link-local address fe80::fe22:1\text{fe80}::\text{fe22}:1 via local interface GigabitEthernet0/1\text{GigabitEthernet0/1}. Complete the Cisco IOS configuration command by filling in the missing parameters in order.

Cevap:ipv6 route 2001:db8:a100:12::/64 【GigabitEthernet0/1】 【fe80::fe22:1】

Cevap

The complete command is: ipv6 route 2001:db8:a100:12::/64 GigabitEthernet0/1 fe80::fe22:1
In Cisco IOS IPv6 static routing, when a link-local address is designated as the next hop, the command must explicitly include the local exit interface preceding the link-local address. Therefore, the first parameter must specify the interface (GigabitEthernet0/1) and the second parameter must specify the link-local address (fe80::fe22:1).

Adım Adım Çözüm

1
Identify the standard Cisco IOS IPv6 static route command structure for link-local next hops.
The command syntax is: ipv6 route <destination-prefix/prefix-length> <exit-interface> <link-local-next-hop>.
Cisco IOS requires specifying the local exit interface when using an IPv6 link-local address as a next hop because link-local addresses are unique only within the scope of a single link.
2
Fill in the required exit interface parameter for the first blank.
blank_1 is GigabitEthernet0/1 (or acceptable interface abbreviation such as gi0/1 or g0/1).
The exit interface specifies which local link to use to resolve the link-local address.
3
Fill in the next-hop IPv6 link-local address for the second blank.
blank_2 is fe80::fe22:1.
The next-hop link-local address follows the exit interface parameter in a fully specified IPv6 static route.
