So me and a friend both bought some new RB units (Rb2011UAS-2HnD).

Previous to this we had Routers running DDWRt.

We had a pTp link running over 2 UBQ NanoSta Loco M5's

The goal is to link the 2 RB's with the pTp link and maintian our independent ISP connections on each side with failover implemented.

We do run plex on each side of the pTp link, so we want devices to be able to see and access that media.

Site 1
WAN (Cable Router) eth1
IP 192.168.0.0/24
pTp 192.168.0.4
PlexMedia 192.168.0.100
other devices (Apple TV, DLNA BluRay, iPad, printers etc)

Site 2
WAN (DSL) eth6
IP 192.168.2.0/24
ptp 192.168.0.5 (eth10 not in bridge of RB)
Plex 192.168.2.143
other devices (Apple TV, DLNA BluRay, iPad, printers etc)

Currently separate subnets, but is that the best way to do this? VLANS?

It's not important to see the AppleTV's between sites so BonJour isn't a great concern. Plex across the link is a must have though.

Besides the link we'll want to implement cost based routing for the GW (the Cable Modem connection is approx 20 times faster) so devices in Site 2 should be using the ptp link to the RB for Internet Connectivity when possible

Thanks for any help.

Questions I'll try to answer promptly

Thanks. I will for sure look at this.

More of a concern is what topology would be best suited for the devices and services we're running. Site 1 consists of 10 devices, Site 2 of 20 devices. We get a solid link on the pTp of 300Mbps (real throughput of 85Mbps Full Duplex).

Most of the Dual WAN Failover stuff I've found deals with 1 Site with 2 ISP Connections. Simple enough with a single router to have two ports configured as GW's (with the proper scripts and costs on the paths). This case of 2 neighbours each with a RouterBoard, each with a ISP connection, wanting to share the GW's and data sitting on each site of the point-to-point WDS is a little different.

I'm somewhat of the opinion that I should have 1 subnet between both sites. This should allow broadcasts to transfer between Sites and insure that Plex Media Server works.

Is there any reason/advantage for me to put the UBNT NSLM5's that are in a pTp WDS configuration into an EoIP ?….would this help or hinder routing (my thought was those 2 devices would then not have to maintain router tables (the EoIP being on top on the link so to speak)

Opinions ?????

Having one common subnet makes problems with DHCP servers. I suggest to have individual subnets with another neutral network between. For simple failover just routing rules together with simple netwatch will do the job.

Can you pls draw the requirement in a paint file? That'll help us better understand the exact requirement.

hope this helps

Since you need L2 connectivity across premises for plex media servers. Why would you install 2 Mikrotik routers in the first place. You could simply bridge LAN on both locations use one single subnet on all devices in both premises.

For internet fail-over, you could get installed both links cable-modem/DSL in same premises and put one router their and let it do the load balancing for you. Or if that's not possible, you could put another PtP link in place to bring the internet link from one premises to the other.

I don't see any reason to install two routers.

I hope, I didn't miss anything.

Installing both ISP connections in one location isn't a viable option.

These devices serve more then just basic connectivity and one of the main reasons for the purchase was the fact that they each have 9 usable ports (or 10 if we populate the sfp slot), where as our previous routers (d-link & buffalo) had 4 usable ports.

Can anyone add to this situation?

Would consider using a single subnet between sites (approx 40 devices) configured with failover on the WAN.

I'm guessing I could configure DHCP on both sites (disable on the DSL Link site) and use some script in the event of a failure on the Cable Modem site to turn on DHCP. Considering that 99% of the time 99% of the devices are known I could use reserved addresses (based on MAC) for devices.

it's simple network map, just take a look at OSPF ... add loopback interfaces of both sides with /32 addresses ...
add backbone networks ... cost for path ... and e.t.c
