Topics discussed.
MPLS HLD- Ann Pokora/Juniper
- Can you explain how Juniper crpD coexists with FRR routing stack in SONiC? >> using build time flags
- How does this feature can be unit tested without crpd ? Ex: Few thoughts - user can push directly to redisDB
- What is the use case are we targeting?
- How does the community can leverage this feature?
- For MPLS, why does it only works withJuniper stack? Is there any MPLS functionality missing in FRR? >> yes there are few fixes from Juniper need to push to FRR community
- Can Juniper open source crpd ? >>> There is internal discussion at Juniper.
- What is the reason fpm syncd in a bgp container instead of switch? >> Can be discussed!!

Topics discussed.SONiC Reproducible Build design - Xuhui
- Shouldn't version control be significant overhead? No - There is a version control file which will take care of dependencies
- Where the version control file is located in the code repo? It is at Docker level right now.
- For instance, If I want to bring a new Python package (it has dependencies) in the docker file it conflicts with the existing one. How to solve it ? You can disable the version check temporarily.
- Does version check framework check dependencies per branch ex: 200911 or 202006? Yes, the version check is per branch to freeze the requirements
- What stage do you freeze on the version? when you move from one debian version to another? We need to regenerate the version file
- Does the build system automatically take care of pulling packages from local storage when the remote website is down ? yes
- How does the framework support for golang libs and dependencies? Not right now, will be included.
- How does version control framework integrate with existing rules file configurations? Do we maintain both version files?

- Why did the design choose a plugin approach for Optical Transceivers? Ans: extensible
- Community feedback:- Though plugin approach is elegant, many vendors have difficulty to implement and validate, it would be nice to solve this problem in a common platform (90% possible).
- Can it be solved using a common platform and if any vendor specific (minimal) make it extendable by different ways (ex: configurations/jinja templating/ plugin etc..)? An optical transceiver working group will be started soon.
- Can the design support DD memory map parsing ? Let's discuss in the working group what to solve in common platform and what else need to extend through plugin or other means

- Are there any examples to understand how PDDF is different from classic/sonic platform API 1.0 ?
- Did you try PDDF API's outside BRCM? Ans : yes ex: Quanta/Inventec / Accton etc.
- Is the above PDDF implementation available publicly? Ans: It is OEM's decision to make it public.
- Can PDDF manage MACSEC based components? Ans: No. MacSEC would be managed by SDK.

- Does this design supports IPv4 un numbered? No, it is only for BGP auto addressing use case
- What is Ipv4 un numbered ? It is a separate feature will use loopback
- Can the feature be renamed BGP un numbered to BGP auto Ipv6 addresses?
- Why do convert Ipv4/rfc5549 routes nexthop to Ipv6 linklocal? Let's keep it Ipv4 link local 169.254.x.x/24 in SoNic similar to industry.
- Can BGP auto IPv6 interfaces support on sub interfaces ? Not tested yet
- Why do disable Ipv6 for BGP auto IPv6 addressing ? The reason - In order to avoid Ipv6 RA's unnecessary on L2 networks . May not need generating interfaces on all the several interfaces
- Will the design supports mulitple vlans with ipv6 link local?
- Is there any global Ipv6 address?
- Is radv db (router advertisements) is used for BGP auto IP ? No linux/frr learns the neighborsCommunity suggested to keep Ipv6 default enabled in sonic for backward compatibility.
- Does this design provide any knob to configure I2ME/128 FE80::/10 catch all route? No
- How does it handle for vlan interface case ?
- How do know when to delete IP2ME routes? If any interface has no refcount - orchagent clean it up

- Why don't leverage ONIE updater, what is the design rational behind the fwUtils?
- What is the significance of chassis? Does Sonic supports multiple chassis?
- Can the design supports module level installations?
- Is the design support remote image path? yes
- What are the supported methods to download images? remote url http/https
- What about the image validations ? ex: compatibility between CPLD/BIOS etc..
- Can user skip/install specific image version using the fwUtils? - you should use it manually [skip the fwUpgrade]
- Can fwUtils supports scheduling of reloads after component updates?

Topics discussed
- Drop Counters HLD - MSFT
Review (Q & A):
- Does the design preserve the counters on warm reboots? No
- Can the design reports the user if the drop counter is not supported with platforms? yes
- List out the caveats with warm reboot cases. Ex: if the device went wrong after warm reboots, does the drop counters distinguish the failure reasons?
- Do we have default settings for the debug counters with the device? No
- Can the design provide any templates for the debug counters to configure it?
- Can the lifecycle (ex: clear)of these counters will not effect the existing counters? No
- Can the design support logical/aggregate debug counters?
- Does these counters are ASIC independent? what platforms do you guys cover it?
- Can this integrate with mgmt framework?

Topics discussed
- BGP Error handling - BRCM
Review (Q & A):
- Is there any perf impact on disable this feature: No
- Data shows the RIB-in convergence performance degradation is 44%, it should be linear, but why is 44%? can it be improved?
- What is the scope of the QuickTests? Is it covered only happy paths alone? do you have numbers with non-happy path scenarios?
- does the QuickTest covers both Ipv4 or Ipv6 ? QuickTest supports mix scenario of ipv4 & ipv6 ? not yet done for pure Ipv6 routes, will be explored.
- do you have any special handling for default route ? No
- Does it supports any debug commands check the failed route ? yes
- What is the reconciliation on daemon crashes (Ex: BGP)- how to reconcile the routes? Please list out the scenarios in HLD.
- Can this feature turn-off on demand ? is yes, can this affect the system stability?

Error Handling - BRCMReview (Q & A):
- Overall framework is thinking about two approaches - 1) Introduce Opaque ID to track the add-delete-add kind of error handling scenarios 2) Introduce an Sync SAI API in addition to current Async SAI API.
- HLD is out for the community review. https://github.com/Azure/SONiC/pull/391

Topics discussed
- Dynamic Port BreakOut HLD - LNKD
Review (Q & A):
- Can't SONiC query SAI API to fetch the break out capabilities?
- Generic question : Why breakout support only per interface? why can' t it per device ? Platform's don't allow certain ports due to silicon issues or the feature is not ready to use the breakout port on this relesase
- Can the breakout feature supports range of ports together?
- Can ASIC vendors support breakout on range/group of ports?
- What does platform vendors do to support this feature? It seems vendors should provide platforms.ini file.
- Can this feature support the list of breakout supported to the user?
- Can breakout feature enforce lanes and aliases to the sonic application?
- Why can't we define platform files per HWSKU?
- Can this HLD covers Platform LED feature?
- How about the configuration validations during port-breakout ? Can this integrate with MGMT framework CVL lib? yes.
