The documentation for lnrpc.RoutingPolicy reveals a boolean discipline referred to as disabled, nevertheless it supplies no definition of what meaning. Every channel has 2 friends, and every peer in a channel has its personal routing coverage. Among the channels have disabled set to true for one peer and false for the opposite.

Right here is an instance:

$ lncli getchaninfo 697113461880782849
{
    "channel_id": "697113461880782849",
    "chan_point": "094c1a9d6cd5294847f560758e8b8d8cdb4ef386ca746112536564742a92184b:1",

        "time_lock_delta": 40,
        "min_htlc": "1000",
        "fee_base_msat": "1000",
        "fee_rate_milli_msat": "10",
        "disabled": false,
        "max_htlc_msat": "5228340000",
        "last_update": 1665821197
    },
    "node2_policy": {
        "time_lock_delta": 24,
        "min_htlc": "1000",
        "fee_base_msat": "0",
        "fee_rate_milli_msat": "501",
        "disabled": true,
        "max_htlc_msat": "5228340000",
        "last_update": 1667018957
    }
}

Is it true {that a} channel is simply lively if the routing coverage for each friends reveals disabled = false?

Or is setting a routing coverage to disabled the equal of setting it to null? Some channels have friends with null routing insurance policies as on this instance:

$ lncli getchaninfo 555817421567164416
{
    "channel_id": "555817421567164416",
    "chan_point": "43a329e374f19ac11cb8377d8d791505d27e60c221a3cfe99a2d758318803e0f:0",
    "last_update": 0,
    "node1_pub": "0207481a19a3f51a48f134e95afa67cfeffdb38a99b5ad3494a320c4918aaaf579",
    "node2_pub": "02ef61a252f9504a42fc264a28476f44cea0711a44b2da0bd729ad52aaee9d86b7",
    "capability": "10000",
    "node1_policy": null,
    "node2_policy": null
}

Is the above channel lively? If that’s the case, does it use default routing coverage values?

Is disabled = true the identical as a null routing coverage? Or does it disable the entire channel if one node disables its routing coverage?
