34.3.18 show ip6 prefix Command
Syntax:
show ip6 prefix
This command displays the the list of on-link prefixes. The prefixes are used to determine whether
an IP address is on the same link as the MSC or should be reached through a router.
A prefix is considered to be on-link when it is assigned to an interface on a link. It's used to
determine if an address is on the MSC's subnet and can be reached directly without passing through
a router. An on-link interface is directly connected to the MSC or connected through another switch.
Table 383 show ipv6 neighbor
LABEL DESCRIPTION
Interface This is the interface on which the IPv6 address is created or through which a
neighbor can be reached.
Neighbor This is the IPv6 address of the MSC’s interface or a neighboring device.
Linklayer Address This is the MAC address of the interface on which the IPv6 address is configured.
Expire This displays how long (hhhmmmsss) an address can be used before it expires. If an
address is manually configured, it displays permanent (never expires).
Flags This field displays whether the neighboring IPv6 interface is reachable. In IPv6,
"reachable" means an IPv6 packet can be correctly forwarded to a neighboring
node (host or router) and the neighbor can successfully receive and handle the
packet. The available options in this field are:
Reachable: The interface of the neighboring device is reachable. (The MSC has
received a response to its neighbor solicitation.)
Stale: The last reachable time has expired or the MSC received an unrequested
advertisement that updates the cached link-layer address from the neighboring
interface.
Delay: A packet is being sent to the neighboring interface in Stale state. The MSC
delays sending request packets for a short time to give upper-layer protocols a
chance to determine reachability. If no reachability confirmation is received within
the delay timer, the MSC sends a neighbor solicitation and changes the state to
Probe.
Probe: The MSC is sending neighbor solicitations and waiting for the neighbor's
response.
Invalid: The neighbor address is an invalid IPv6 address.
Unknown: The status of the neighboring interface can not be determined.
Incomplete: Address resolution is in progress and the link-layer address of the
neighbor has not yet been determined (see RFC 4861). The interface of the
neighboring device did not give a complete response.
R: The neighboring device is a router.
