Syntax

Hierarchy Level

Description

Configure Mapping of Address and port – Encapsulation (MAP-E) as an inline service on MX Series routers that use MPC and MIC interfaces. MAP-E is an automatic tunneling mechanism that encapsulates IPv4 packets within an IPv6 address. The IPv4 packets are carried in an IPV4-over-IPV6 tunnel from the MAP-E Customer Edge (CE) devices to the MAP-E Provider Edge (PE) devices (also called as Border Relay (BR) devices) through an IPV6 routing topology, where they are de-tunneled for further processing.

Options

confidentiality

Configure Junos MAP-E confidentiality. This helps to hide MAP-E rule parameters in CLI show commands and logs.

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.

name

Name of the MAP-E softwire concentrator.

ea-bits-len

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

Note:
  • If v4-prefix-len is 0 then ea-bits-len must be non-zero, and vice versa.

  • It is possible that ea-bits-len is equal to 0, but psid-len is non-zero.

  • 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 48

ipv4-prefix

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

  • Range: 0 through 32

mape-prefix

Configure rule for IPV6 prefix and length for the MAP-E domain. The MAP-E IPv4 and IPv6 prefix must be unique per softwire concentrator.

mtu-v6

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

  • Default: 9192

  • Range: 1280 through 9192

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

softwire-address

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

v4-reassembly | v6-reassembly

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

version-03

(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.
