softwire-types (Next Gen Services)

Syntax

Hierarchy Level

Description

Configure ds-lite, 6rd and MAP-E softwire objects.

Options

The following options are available for each type of softwire:

ds-lite

Specify options for DS-Lite softwites.

v6rd

Specify options for v6rd softwites.

map-e

Specify options for map-e softwires.

auto-update-mtu

This option is not currently supported.

copy-dscp

Copy DSCP information to IPv4 headers during decapsulation.

flow-limit

—Maximum number of IPv4 flows per softwire.

ipv4-prefix

IPv4 prefix of the customer edge (CE) network

mtu-v4

Maximum transmission unit (MTU), in bytes (576 through 9192), for IPv6 packets encapsulated into IPv4. If the final length is greater than the configured value, the IPv4 packet is dropped. This option is mandatory except for DS-Lite softwires since it depends on other network parameters under administrator control.

mtu-v6

Maximum transmission unit when encapsulating IPv4 packets into IPv6. If the final length is greater than the MTU, the IPv6 packet is fragmented. This option is mandatory since it depends on other network parameters under administrator control.

session-limit-per-prefix

Maximum number of sessions per B4 subnet prefix.

softwire-concentrator

Specify the IP address of the softwire concentrator.

softwire-type

Sets softwire concentrator type to 6rd.

  • Values: v6rd

v6rd-prefix

IPv6 prefix for the 6rd domain.

For map-e softwires:

Options for MAP-E rules:

name

Name of the MAP-E softwire domain name.

br-address

Specify the Border Relay (BR) device unicast IPv6 address as the softwire concentrator IPV6 address.

version

3(Optional) Configure version number to distinguish between currently supported version of the Internet draft draft-ietf-softwire-map-03 (expires on July 28, 2013), Mapping of Address and Port with Encapsulation (MAP) and the latest available version.

rule

Specify the name of Map-E the rule.

v4-reassembly | v6-reassembly

(Optional) Enable IPv4 and IPv6 reassembly for MAP-E.

disable-auto-route

Disable auto-routes and enable static routes to facilitate ECMP load balancing.

Note:

When you enable the disable-auto-route option, you must configure static routes.

ipv4-prefix

Configure rule for IPv4 prefix of the MAP-E domain.

ipv6-prefix

Configure rule for IPv6 prefix of the MAP-E domain.

ea-bits-length

Configure rule for Embedded Address (EA) length for the MAP-E domain.

  • Range: 0 through 48

psid-length

Configure Port Set ID (PSID) length value for the MAP-E domain.

Note:
  • If the sum of v4-prefix-len and ea-bits-len is less than 32, then the psid-len must be equal to the difference between 32 and the sum total of v4-prefix-len and ea-bits-len.

  • Range: 0 through 16

psid-offset

(Optional) Configure PSID offset value for the MAP-E domain.

  • Default: 4

  • Range: 0 through 16

mtu-v6

(Optional) Specify the Maximum transmission unit (MTU) for the MAP-E softwire tunnel.

  • Default: 9192

  • Range: 1280 through 9192
