1801 adding 4G port

[apear2016]

Hello all,

I have an 1801 router.

FE 1 to 4 are a bonded dialer group with an ISP via per packet share diallers 1 to 4 on VLANs 101 to 104 respectively (4 ADSL lines using PPOE). The WAN of the router goes to the managed switch for the system (NO DHCP required from the 1801 on the WAN) - setup as the internet gateway.

I wish to add a 4G router to the 1801 for more UP speed and dialer group (ADSL lines) failback redundancy on FE5.

FE5 is to be on the default VLAN1 (or any VLAN defined) via DHCP from the 4G router LAN.

Help on the metrics, routing and config for the router to achieve this please ??

Basically - I would like the 4G router on port FE5 to be part of a load sharing group, sharing with the dialer group on a season based load sharing / redundancy.

That is, if FE1 to 4 dialer group fail / FE5 takes over - and vis vera.

However , if possible, I would also like a metric to load share FE5 with FE1to4 diallers for more bandwidth when all is well.

Regards,

Warren

I would be interested to see the relevant 1801 configuration. I suspect normally you would want the traffic to go thru the 4G router,as should have a lot higher bandwidth.The Internet gateway will be the 4G router. Then I would setup some Ip SLA configuration say pinging 8.8.8.8 out of Fe5, if that fails then using EEM scripts change the default gateway to the router on the  ADSL group. Once the 4G route comes back up swap the default gateway back to the 4G router with another EEM script

The 1801 is setup as a load sharing internet gateway - wan side to main server (firewall_DHCP _ switch_clients).

At the moment - the 4 ADSL2+ lines do all the internet work (FE1 to4) - in a packet share 4 line Dailer bond to the ISP (FE1 to 4 running the PPPoe bridged to PPPoa ADSL modems)

The download is - 20Mb + , Upload 3 to 5Mb. Cheap data and good constant speeds / pings (so far to date as the copper is behaving :-).

Adding the 4G LTE connection is for redundancy mainly. Google ping for connection status sounds fine.

However - the up speed advantage of the 4G LTE would be great to make use of, in this case, LTE data is expensive - so just up speed is the main target during load sharing (if possible).

As many of the clients applications are going to the cloud - increased up speed is goal.

So I would like to setup a session based load balance between the ADSL dialer group and the 4G LTE router using FE5. With 'WAN to 4G LTE port (FE5)' as a priority for the up traffic, perhaps in the QOS?

But still have the failover function to move all the traffic away from a failed connection (dailer group or the 4G LTE) is one goes missing.

I have limited experience with setting up load balancing metrics with failover and was hoping some-one has done this very thing or similar and can share some code or ideas?

Warren,

I don't know how you could LB using QOS. As you say perhaps somebody else does.

Please see the link below regarding load balancing

You could setup Policy based routing(PBR) so that certain traffic always goes thru the 4G connection
