vPC peering aware run for dcnm_link | vpc peering link prepare | backlog | Good to have #88

Open rrahimm opened 6 months ago

rrahimm commented 6 months ago

We currently use dcnm_links module to prepare links for vpc_peering. and we use the policy "int_pre_provision_intra_fabric_link" for preparing the links.

once this is done and vpc_pairing module pairs the switches, the policy is changed from int_pre_provision_intra_fabric_link to none.

Before Example

[
{
    "link-uuid": "LINK-UUID-375050",
    "is-present": false,
    "link-type": "lan_planned_link",
    "is-discovered": false,
    "is-planned": true,
    "sw2-info": 
{},
"link-dbid": 531270,
"nvPairs": 
{},
"policyId": "POLICY-531280",
"templateName": "int_pre_provision_intra_fabric_link",
"is-port-channel": false,
"sw1-info": 
    {},
    "fabricName": "netascode_fabric4"
},

After Example

{
    "link-uuid": "LINK-UUID-105050",
    "is-present": true,
    "link-type": "ethisl",
    "is-discovered": false,
    "is-planned": false,
    "sw2-info": 
{},
"link-dbid": 510380,
"is-port-channel": false,
"sw1-info": 

    {},
    "port-channel-id": 510670
},

Due to this, everytime we eun the dcnm_links its no more behaving as idempotent and keeps trying to pull the template back to "int_pre_provision_intra_fabric_link" (it doesn't seem to succeed though).

Rerun of dcnm_links for a already provisioned vpc peer link

The action is to add intelligence to the prepare link task to skip dcnm_link preparation when the vpc is already paired.
