title: Weave Net Router Sleeve Encapsulation
menu_order: 10
search_type: Documentation

When the Weave Net router forwards packets to peers in `sleeve` mode
(rather than via the [fast data path](/site/using-weave/fastdp.md)), the
encapsulation looks something like this:

    +-----------------------------------+
    | Name of sending peer              |
    +-----------------------------------+
    | Frame 1: Name of capturing peer   |
    +-----------------------------------+
    | Frame 1: Name of destination peer |
    +-----------------------------------+
    | Frame 1: Captured payload length  |
    +-----------------------------------+
    | Frame 1: Captured payload         |
    +-----------------------------------+
    | Frame 2: Name of capturing peer   |
    +-----------------------------------+
    | Frame 2: Name of destination peer |

    | Frame 2: Captured payload length  |
