| 09:55:43 | bauzas | sean-k-mooney: your last sentence on the fact that an agent RP seems irrelevant puzzles me | |

| 09:58:31 | gibi | bauzas: I also imagine that the segment RP providign IP resources should be sharing the IP resource to the agent RP, but technically sharing with the compute RP is OK too I guess | |

| 10:00:16 | sean-k-mooney | similar to the physnet net which is scoped to the bridge | |

| 10:01:09 | gibi | yeah then it make more sense to share the IP with the physnet birdge | |

| 10:01:57 | bauzas | so, we model a tree of an agent RP and the bridge RP | |

| 10:02:08 | sean-k-mooney | yes | |
| 10:03:01 | bauzas | and since mimimum bandwidth SLAs are on the bridge, we have the egress/ingress RCs attached to the bridge RP | |

| 10:03:17 | sean-k-mooney | one of the reason for havign the agent RP was also quick lookup of the RP by using the agent uuid | |

| 10:03:48 | gibi | agent RP -> OVS RP -> bridge RP would be the tree | |

| 10:04:00 | bauzas | gotcha | |

| 10:04:04 | gibi | and therefore the bridge would need to move under a new parent | |

| 10:04:19 | bauzas | well | |
| 10:04:19 | bauzas | well | |
| 10:05:13 | sean-k-mooney | gibi: i still come back to could we model the invetory on br-int and perhap even remvoe the agent rp | |

| 10:05:20 | bauzas | * bauzas wonders whether it's just simplier to consider that the existing agent RP we created for the purpose of the bandwidth spec is just a OVS RP | |
| 10:05:31 | sean-k-mooney | gibi: to avoid needing to move the bridge that were moved by the bug in neutorn | |
