Hi Babine, you mean below traffic flow design: Refer BRKCRS-2142 (ciscolive.com) However you might need a support case to confirm.

Hi Babine, In that case, and based on what you mentioned in the post; The issue might be the failover did not work, and the challenge is it is not working even you failback to primary connection; you may need baseline your normal primary connection telephone traffic then comparing it with the failover one. It could be same issue on below post in 2019, and it is stateful firewall related; it could be already be addressed in the new code, not sure yet; for the time being, you can try ' disable/enable BACKUP interface' 🙂 VoIP problem with stack SIP with the MX WAN connectivity failover - The Meraki Community My understanding is you may need a support ticket when the failback reconverge did not work. Happy to help! Best Regards,

GregLiu

You can using more than one SIP trunk if it is possible, depending the PBX you are using; troubleshooting to find out why it is not working even the link failback, the phone or phone system may have log; As for SBC you can enabled Active-Active I think, there is a call routing control, most of time, the Telco can re-route the incoming call, however, for outgoing call, it need enable Active-Active call control or Active-standby call control.

It seems there is easy way to solve this, and Microsoft has introduced Router Server as a control plane, fyi below: https://docs.microsoft.com/en-us/azure/route-server/overview it is still in public preview stage, if anyone like to try it out, there following is github has more details; it is routing control plane in Azure which could be used via BGP to peering with vMX and peering with MS VNET as well.

Agreed that there is a misleading on this picture. Make sense, two MXs in front of the MX concentrator HA pair, then the ebgp can be utilized to Big office internal network or Datacenter internal core, and autovpn ibgp as wan fibric network :). Let say, the front MX working as firewalls, inspect traffic for DIA and internet underlay path resilience, and this will allow to use full feature sets of the firewalls functions, and the concentrator HA pair designed for terminating the autovpn fibric connections only. However, if the routed mode MX can keep all feature sets, then converge the front end MX and concentrator HA pair into one pair will save two front end MX or firewalls :).

🙂 This is make sense solution, as it is support ospf and static with route mode :); the ebgp support will make some network migration more smooth as so much feature sets, and easy to scale out; like the idea on talking to support get the bgp enabled for testing only, not production until it is officially supported and CVD verified it. just some thought, it would be nice if the MX able to converge these Routed, NATing, security and routing protocol ebgp, regardless the fate-sharing drawback; However, the modular design from CVD is nice! anyway, thanks a lot for these info. Cheers,

Hi team, Anyone using below topology for DC or Central office HUBs, Primary and Secondary for the WAN connection, the Concentrator for the BGP autovpn, then the concentrator ebgp peering with existing IOS core network: Seems it is recommended by the CVD 🙂 Cheers, Greg

Hi Guys, Just wondering that any technical reason the routed mode with NATed enabled MX, the bgp autovpn can not support EBGP peering with IOS based devices? it seems only support static for the current released code. Cheers, Greg

Just a network engineer since 1990s 🙂 Pretty interested in Meraki API calls, and like to understand more about operational API calls can do. Cheers Greg
