Use ULAs instead of LL. No need to use filters or static this way.

Re: CLOUD CORE ROUTER

Normis,

Maybe it is not...

Seems like the new ethernet buffer optimization for CCR is causing the problem. When I started btest from CCR using direction=transmit and Local TX Speed=95Mbps test took 5 minutes and I saw no problem. When I changed Local TX Speed to 98Mbps the problem shows up!

Re: CLOUD CORE ROUTER

Normis,

Actually the problem is something about "management" process. I started test from 2 RBs 751 using direction=transmit and I saw no problem.
But when I started test from one RB 751 using direction=receiving "management" process reaches 6% on CCR1016 and after 90 seconds the router reboot.

Re: Problem with wilreless point to point

brunoms86,

You don't need too much to this short link. If you didn't change default TX POWER try to low it at least to 10dbm in both sides and try again.
Keep in mind that -40 is not a good signal. There is too much power in your system. Always try to keep it around -60dbm, ok?

If you use walled garden it will not work fine. You must use IP BINDINGS to make the correct test.

Re: 2 peers, 4 /24 prefix and load balance outbound

Upload is really easy. You need to create a ECMP route with check-gateway enabled. Just add both gateways in the same static route. The traffic will be share using round-robin every time source or destine address change. This way you can reach a good balance. Try it and tell us, ok?

Re: Losing VPN connections when changing default route

Uncheck "Add default route" in your VPN client and add the default route manually. At this point do not use the IP address as gateway. Use the vpn interface as gateway.

This way you don't need to change the default route anymore, ok?

Keep you balance the way you are doing and you also can announce your /22 in both peers. If one peer goes down all traffic will be redirect to the other peer.

The default tx power is 17dbm and when you are using 2x2 you will get 3dbm extra and 200 meters is really close. Try to decrease TX power using card rates and set it to 7 dbm.
