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-partial-reassembly	(Optional) Enable IPv4 partial reassembly for MAP-E.
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.
