Hi, Does anyone have Meraki documentation related to BGP best-path selection algorithm? From my testing environment I've noticed that a MX in one-armed concentrator mode (the only mode that supports eBGP) always prefers the eBGP route over iBGP route (it doesn't care of AS-PATH length) Ex: R1(AS 100)----eBGP----HUB1-----iBGP(AS 65100)-----HUB2----R2 (AS 200) R1 advertises subnet 10.10.10.10/32 with AS path 100 100 100 R2 advertises subnet 10.10.10.10/32 with AS path 200 --> Hub1 prefers the external route from R1 (would expect to prefer the route from Hub2) --> Hub2 prefers the external route from R2 (expected behavior) --> If R1 stops advertising 10.10.10.10/32, then Hub1 will receive the route from Hub2 via iBGP with AS PATH 65100 200 --> If Spoke 1 has in the hub list HUB1(primary) HUB2(secondary), it will prefer the route from HUB2 with AS PATH 65100 200 thanks

Hi kYutobi, I've already read the doc that you've provided, but what I've asked is not in this document (in short, if you don't specify/limit the uplink bandwidth, and if from the provider you've bought only 10Mb, what will be the reference bandwidth used for High Normal and Low clases? Meraki doc says: +++++++++++++++ Each traffic rule supersedes each rule below it and the rules below it must strictly adhere to their fractional bandwidth limits. For instance, if there is a high traffic shaping rule but no low traffic shaping rules configured then the high priority traffic would have access to 5/7 of the available bandwidth on the uplink and normal traffic would have 2/7s. Additionally, if there are no high priority traffic shaping rules then normal priority traffic gets 6/7 of the bandwidth and low priority gets 1/7 of the uplink's bandwidth. +++++++++++++++

Hello, Meraki documentation states: Priority can be set to High, Normal, or Low, allowing the MX series to prioritize a given network flow relative to the rest of the network traffic. The ratios are as follows: High: 4/7 Normal: 2/7 Low: 1/7 Considering that --> Carrier has provided a 10Mb uplink --> Wan uplinks have no limitation defined (see below) --> all the SD-wan traffic shaping rules have the Bandwidth limit: "Ignore network per-client (unlimited) --> there 2 High priority rules, 2 Normal priority rules and 1 Low priority rule How is the traffic prioritized/bandwidth utilization done in this case? thanks

Hi MerakiDave, Thank you for your reply, do you have any official Meraki documentation where it explains this?

Hi, In a Hub and Spoke design, if 2 spokes are using different HUB priorities (lets say Spoke1 - Hub1;Hub2 and Spoke2 - Hub2; Hub1), and both Hubs advertise all subnets, how is the traffic flow going to be between Spoke 1 and Spoke 2? -- Spoke1 -- Hub1 -- Spoke2 and return(reply) traffic Spoke 2 -- Hub2 -- Spoke 1 or -- Spoke1 -- Hub1 -- Spoke 2 and return(reply) traffic Spoke2 -- Hub1 -- Spoke1 (symmetrical) thanks
