meraki active active branch setup

How do you setup an active active HA configuration at the branch with two internet access circuits?

Kind of a big deal

If you mean load balancing between the two internet circuits check the link:

If you mean active-active HA configuration using two MX's, you can't Meraki doesn't support active-active HA, only warm spare. Recommended topologies can be seen here:

does meraki MX support routing protocol on the LAN side, BGP, OSPF?

 

does meraki mx supports routing protocol on the LAN side (BGP, OSPF)?

It supports OSPF on the LAN-side, it only advertises the subnets available through AutoVPN. So it's not full blown OSPF support. It can't learn routes, and I don't think it advertises anything towards the WAN side either:

Pretty sure the same is true for it's BGP support that is in beta at the moment (so you need to contact helpdesk to have it activated). More info here:

For BGP, you can advertise your LAN subnet, such as a connected network through EBGP between peers.

 

For example;

 

<Your L3 Core switch>

router bgp 64555 <--Your DC AS number
bgp log-neighbor-changes
neighbor 192.168.19.52 remote-as 64512 <--Meraki iBGP
neighbor 192.168.19.52 timers 60 180
!
address-family ipv4
redistribute connected route-map SERVER_CONNECTED
neighbor 192.168.19.52 activate
neighbor 192.168.19.52 soft-reconfiguration inbound
exit-address-family

 

route-map SERVER_CONNECTED permit 10
match ip address prefix-list SERVER_SUBNET

 

ip prefix-list SERVER_SUBNET seq 5 permit 192.168.132.0/24

 

 

DC2-SW1#show ip route conn

Gateway of last resort is 192.168.19.41 to network 0.0.0.0

C 192.168.132.0/24 is directly connected, Vlan503
L 192.168.132.1/32 is directly connected, Vlan503
