Router interface IPv6 commands

ipv6

Syntax

[no] ipv6

Context

config>router>interface

Platforms

Supported on all 7210 SAS platforms as described in this document

Description

This command configures IPv6 for a router interface.

The no form of this command disables IPv6 on the interface.

Default

no ipv6

address

Syntax

address {ipv6-address/prefix-length} [eui-64]

no address {ipv6-address/prefix-length}

Context

config>router>if>ipv6

Platforms

Supported on all 7210 SAS platforms as described in this document

Description

This command assigns an IPv6 address to the interface.

Parameters

ip-prefix

Specifies the IPv6 address on the interface in dotted-decimal notation.

Values

ipv6-address

x:x:x:x:x:x:x:x (eight 16-bit pieces)

x:x:x:x:x:x:d.d.d.d

x - 0 to FFFF (hexadecimal)

d - 0 to 255 (decimal)

prefix-length

Specifies the mask associated with the network address expressed as a mask length.

Values

ipv6-prefix-length -

0 to 128

eui-64

Specifies that a complete IPv6 address from the supplied prefix and 64-bit interface identifier is formed. The 64-bit interface identifier is derived from MAC address on Ethernet interfaces. For interfaces without a MAC address, for example POS interfaces, the Base MAC address of the chassis should be used.

icmp6

Syntax

icmp6

Context

config>router>if>ipv6

Platforms

Supported on all 7210 SAS platforms as described in this document

Description

Commands in this context configure ICMPv6 parameters for the interface.

Syntax

packet-too-big [number seconds]

no packet-too-big

Context

config>router>if>ipv6>icmp6

Platforms

Supported on all 7210 SAS platforms as described in this document

Description

This command configures the rate for ICMPv6 packet-too-big messages.

Parameters

number

Specifies that the number of packet-too-big messages issued per the time frame specified in the seconds parameter will be limited.

Values

10 to 1000

seconds

Specifies the time frame, in seconds, that is used to limit the number of packet-too-big messages issued per time frame.

Values

1 to 60

param-problem

Syntax

param-problem [number seconds]

no param-problem

Context

config>router>if>ipv6>icmp6

Platforms

Supported on all 7210 SAS platforms as described in this document

Description

This command configures the rate for ICMPv6 param-problem messages.

Parameters

number

Specifies that the number of param-problem messages issued per the time frame specified in the seconds parameter will be limited.

Values

10 to 1000

seconds

Specifies the time frame, in seconds, that is used to limit the number of param-problem messages issued per time frame.

Values

1 to 60

redirects

Syntax

redirects [number seconds]

no redirects

Context

config>router>if>ipv6>icmp6

Platforms

Supported on all 7210 SAS platforms as described in this document

Description

This command configures the rate for ICMPv6 redirect messages. When configured, ICMPv6 redirects are generated when routes are not optimal on the router and another router on the same subnetwork has a better route to alert that node that a better route is available.

The no form of this command disables ICMPv6 redirects.

Default

100 10

Parameters

number

Specifies that the number of redirects issued per the time frame specified in the seconds parameter will be limited.

Values

10 to 1000

seconds

Specifies the time frame, in seconds, that is used to limit the number of redirects issued per time frame.

Values

1 to 60

time-exceeded

Syntax

time-exceeded [number seconds]

no time-exceeded

Context

config>router>if>ipv6>icmp6

Platforms

Supported on all 7210 SAS platforms as described in this document

Description

This command configures rate for ICMPv6 time-exceeded messages.

Parameters

number

Specifies that the number of time-exceeded messages issued per the time frame specified in seconds parameter will be limited.

Values

10 to 1000

seconds

Specifies the time frame, in seconds, that is used to limit the number of time-exceeded messages issued per time frame.

Values

1 to 60

unreachables

Syntax

unreachables [number seconds]

no unreachables

Context

config>router>if>ipv6>icmp6

Platforms

Supported on all 7210 SAS platforms as described in this document

Description

This command configures the rate for ICMPv6 unreachable messages. When enabled, ICMPv6 host and network unreachable messages are generated by this interface.

The no form of this command disables the generation of ICMPv6 host and network unreachable messages by this interface.

Default

100 10 (when IPv6 is enabled on the interface)

Parameters

number

Specifies the number destination unreachable ICMPv6 messages to issue in the time frame specified in seconds parameter.

Values

10 to 1000

seconds

Sets the time frame, in seconds, to limit the number of destination unreachable ICMPv6 messages issued per time frame.

Values

1 to 60

link-local-address

Syntax

link-local-address ipv6-address [preferred]

no link-local-address

Context

config>router>if>ipv6

Platforms

Supported on all 7210 SAS platforms as described in this document

Description

This command configures the link local address.

local-proxy-nd

Syntax

[no] local-proxy-nd

Context

config>router>if>ipv6

Platforms

Supported on all 7210 SAS platforms as described in this document

Description

This command enables local proxy neighbor discovery on the interface.

The no form of this command disables local proxy neighbor discovery.

proxy-nd-policy

Syntax

proxy-nd-policy policy-name [policy-name...(up to 5 max)]

no proxy-nd-policy

Context

config>router>if>ipv6

Platforms

Supported on all 7210 SAS platforms as described in this document

Description

This command configure a proxy neighbor discovery policy for the interface.

Parameters

policy-name

Specifies the neighbor discovery policy name. Allowed values are any string of up to 32 characters, composed of printable, 7-bit ASCII characters. If the string contains special characters (#, $, spaces, etc.), the entire string must be enclosed within double quotes. The specified policy name must already be defined.

neighbor

Syntax

neighbor [ipv6-address] [mac-address]

no neighbor [ipv6-address]

Context

config>router>if>ipv6

Platforms

Supported on all 7210 SAS platforms as described in this document

Description

This command configures an IPv6-to-MAC address mapping on the interface. Use this command if a directly attached IPv6 node does not support ICMPv6 neighbor discovery, or for some reason, a static address must be used. This command can only be used on Ethernet media.

The ipv6-address must be on the subnet that was configured from the IPv6 address command or a link-local address.

Parameters

ipv6-address

Specifies the IPv6 address assigned to a router interface.

Values

ipv6-address -

x:x:x:x:x:x:x:x (eight 16-bit pieces)

x:x:x:x:x:x:d.d.d.d

x - 0 to FFFF (hexadecimal)

d - 0 to 255 (decimal)

mac-address

Specifies the MAC address for the neighbor in the form of xx:xx:xx:xx:xx:xx or xx-xx-xx-xx-xx-xx.
