Context

config>service>ies>if>ipv6

config>service>vprn>if>ipv6

Platforms

Supported on all 7210 SAS platforms as described in this document

Description

This command assigns an IPv6 address to the IES interface.

Parameters

ipv6-address/prefix-length

Specify the IPv6 address on the interface.

Values

ipv6-address/prefix: ipv6-address x:x:x:x:x:x:x:x (eight 16-bit pieces)

  • x:x:x:x:x:x:d.d.d.d

eui-64

Keyword to specify 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.

Description

This command specifies whether ‟parameter-problem” ICMPv6 messages should be sent. When enabled, ‟parameter-problem” ICMPv6 messages are generated by this interface.

The no form of this command disables the sending of ‟parameter-problem” ICMPv6 messages.

Default

100 10

config>service>vprn>if>ipv6>icmp6

Platforms

Supported on all 7210 SAS platforms as described in this document

Description

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

When disabled, ICMPv6 redirects are not generated.

Default

redirects 100 10

Parameters

number

Specifies the number of version 6 redirects that are to be issued in the time frame specified by the seconds parameter.

Values

10 to 1000

Default

100

seconds

Specifies the time frame in seconds that is used to limit the number of version 6 redirects issued.

Values

1 to 60

Default

10

time-exceeded

Syntax

time-exceeded [number seconds]

no time-exceeded

Platforms

Supported on all 7210 SAS platforms as described in this document

Description

This command specifies whether ‟time-exceeded” ICMPv6 messages should be sent. When enabled, ICMPv6 ‟time-exceeded” messages are generated by this interface.

When disabled, ICMPv6 ‟time-exceeded” messages are not sent.

Default

time-exceeded 100 10

number

Specifies the number of ‟time-exceeded” ICMPv6 messages that are to be issued in the time frame specified by the seconds parameter.
