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.
|
| 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 |
| 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.
|
| psid-length | Configure Port Set ID (PSID) length value for the MAP-E domain. Note:
|
| psid-offset | (Optional) Configure PSID offset value for the MAP-E domain.
|
| mtu-v6 | (Optional) Specify the Maximum transmission unit (MTU) for the MAP-E softwire tunnel.
