Help installing secondary BH between tower sites

i second the use of bridging as it will be much easier to setup/troubleshoot especially if you are not real familiar with routing protocols.

Yeah that is true nucoles ! Thanks

unless you have someone on staff that understands routing I would probably just leave it a bridged network by :

Create Bond between 2 interfaces (Interface 2 -3)
and then create a Bridge between (Bonding1 and Interface 1 on Tower B Router)

Meanwhile Doing the Same thing on Tower A as well.

I have never setup a bridge across a bond before but it should act properly...

I take it as you have every one of your customers Double nat'd ? Unless they request it otherwise?


When creating the bond on ether2 and ether3 with ARP monitoring what IP addressing do I enter in the ARP IP targeting the IP of ether1 or do I assign ether2 and ether3 an address and enter those in?

use the bonding interface ip address of the opposing router.

I have figured out the ARP IP part now I know that the target has to be the other routers bond I have created bonds on both routers

how do i disable the dhcp and assign a static ip to ether1 port which is the gateway. I tried to disable the dhcp client and assign a ip but it lost its connection

So you have ether 1 setup under DHCP-SERVER? or DHCP-CLIENT?

you should not have either of those

You should assign ‘STATIC’ IP with /ip address add address=x.x.x.x/24 interface=ether1

also you probably will want to add a /ip route add dst-address=0.0.0.0/0 gateway=(IP FROM NEIGHBORING ROUTER)

that way it has a default route to get back to Tower A

When I try to ping 192.168.1.1 or google.com’s ip from tower b I get a lot of packet loss from tower a I get no packet loss the reply I get when I ping is 192.168.100.1 92 byte redirect host (5:1) time<1 msFollowed by 192.168.1.1 ping timeout
The 192.168.1.1 is the router at our head end I just have it setup in the office right now for testing before we implement the devices.


Ok for tower a this is my setup
ether 1 ip = 192.168.1.21
ether 2 & 3 bonding 1 ip = 192.168.100.1

route list
AS dst add = 0.0.0.0/0 Gateway 192.168.1.1 reachable bridge 1
DAC dst add = 192.168.1.0/24 Gateway Bridge 1 Reachable
DAC 192.168.100.0/24 Gateway bridge 1

tower b
ether 1 ip = 192.168.2.21
ether 2 & 3 bonding 1 ip = 192.168.100.2

Route List
AS dst add = 0.0.0.0/0 Gateway 192.168.1.1 reachable bonding 1
AS dst add = 192.168.1.0/24 Gateway 192.168.100.1 reachable bonding 1
DAC dst add = 192.168.2.0/24 Gateway ether 1 reachable
DAC dst add = 192.168.100.0/24 Gateway bonding 1 reachable

Any input you guys have would be awesome thanks for all the great replies so far they have really helped out.
