show ipconfig ipv6

show ipconfig ipv6 {vlan vlan_name | tunnel tunnel_name}

Description

Displays configuration information for one or more interfaces in the current VR context.

Syntax Description


`vlan_name`	Specifies an IPv6 configured VLAN.
`tunnel_name`	Specifies an IPv6 tunnel.

Default

N/A.

Usage Guidelines

If no interface is specified, then global IPv6 configuration is displayed. Otherwise, specific interface(s) will be displayed. Global IPv6 configuration information includes:

IPv6 address/netmask/etc.
IPv6 forwarding information/IPv6 multicast forwarding information

Example

The following example displays configuration information on a VLAN "accounting":

show ipconfig ipv6 vlan accounting

The current and configured values for max-gateways now apply to IPv6 gateway sets as well as IPv4, so these values are added to the output:.

# show ipconfig ipv6  
Route Sharing : Disabled    
ICMP Redirect for Fast Path : Disabled    
Max Shared Gateways : Current: 32 Configured: 32

The configuration settings for static route ping protection enable/disable, interval, and misses also appear:

# show ipconfig ipv6
Route Sharing : Enabled
Route Compression : Enabled
ICMP Redirect for Fast Path : Disabled
Max Shared Gateways : Current: 16 Configured: 16
Route Sharing Hash : CRC Lower
Ping Protection : Enabled for static routes Interval: 2 Misses: 3
IPV6 Anycast MAC            : 00:00:AB:BA:BA:BA

The following example displays configuration information for ICMP multicast and anycast echo requests (lines 4-5):

# show ipconfig ipv6
    Route Sharing               : Disabled
    Route Compression           : Enabled
    Ignore ICMP Multicasts      : Enabled
    Ignore ICMP Anycasts        : Enabled
    ICMP Redirect for Fast Path : Disabled
    Max Shared Gateways         : Current: 16  Configured: 16
    Route Sharing Hash          : CRC Lower, Default Method
    Ping Protection             : Enabled for static routes   Interval: 2   Misses: 3
    IPv6 Anycast MAC : None

The following example displays configuration information with TCP MSS adjustment support (lines 2 and 9):

# show ipconfig ipv6 v61
Router Interface on v61 is enabled.  MTU: 1500  TCP-MSS: 0
    IPv6 Hop Limit: 64
    Locally registered unicast addresses:
        fe80::a01:101%v61/64 (Tentative)
    Flags:
        IPv6 Forwarding: YES   Accept recvd RA:  NO
         Send redirects: YES  Accept redirects:  NO
         TCP Adjust MSS: OFF
