Displaying global IPv6 information
Displaying IPv6 cache information
The IPv6 cache contains an IPv6 host table that has indices to the next hop gateway and the router
interface on which the route was learned.
To display IPv6 cache information, enter the following command at any CLI level.
Syntax: show ipv6 cache [<index-number> | <ipv6-prefix>/<prefix-length> | <ipv6-address> |
ethernet <port> | ve <number> | tunnel <number>]
The <index-number> parameter restricts the display to the entry for the specified index number
and subsequent entries.
The <ipv6-prefix>/<prefix-length> parameter restricts the display to the entries for the specified
IPv6 prefix. You must specify the <ipv6-prefix> parameter in hexadecimal using 16-bit values
between colons as documented in RFC 2373. You must specify the <prefix-length> parameter as a
decimal value. A slash mark (/) must follow the <ipv6-prefix> parameter and precede the
<prefix-length> parameter.
The ethernet | ve | tunnel parameter restricts the display to the entries for the specified interface.
The <ipv6-address> parameter restricts the display to the entries for the specified IPv6 address.
You must specify this parameter in hexadecimal using 16-bit values between colons as
documented in RFC 2373.
If you specify an Ethernet interface, also specify the port number associated with the interface. If
you specify a VE interface, also specify the VE number. If you specify a tunnel interface, also specify
the tunnel number.
This display shows the following information.
TABLE 66 IPv6 cache information fields
Field Description
Total number of cache entries The number of entries in the cache table.
IPv6 Address The host IPv6 address.
Next Hop The next hop, which can be one of the following:
• Direct – The next hop is directly connected to the router.
• Local – The next hop is originated on this router.
• <ipv6 address> – The IPv6 address of the next hop.
Port The port on which the entry was learned.
