— Exhibit — — Exhibit — Click the Exhibit button. You run the command show interfaces terse
ge-1/0/0 and see the output shown in the exhibit. Why are two addresses being shown for
this interface?
A.
An IPv6 address conflict is being seen; verify your interface configuration for problems.
B.
The two addresses being seen are the link-local and site-local.
C.
Two addresses are assigned in IPv6, one for the physical and one for the logical
interface.
D.
Two addresses are seen because the loopback address of the router is associated with
the interface.
Address Scope
IPv6 addresses have scope, which identifies the application suitable for the address. Unicast and multicast addresses support scoping.
Unicast addresses support two types of scope: global scope and local scope. There are two types of local scope: link-local addresses and site-local addresses. Link-local unicast addresses are used within a single network link. The first ten bits of the prefix identify the address as a link-local address. Link-local addresses cannot be used outside a network link. Site-local unicast addresses are used within a site or intranet. A site consists of multiple network links, and site-local addresses identify nodes inside the intranet. Site-local addresses cannot be used outside the site.
