balancing link

[Felipe]

Good afternoon,In a client must perform a link balancing between two locations. The interlinking between them, atualemente, is performed through radio (Radwin), however the client requests to be balanced (50% and 50%) the traffic with an optical fiber. The port is gigabit and Fibre is 100.
What would be the best possible way?
LACP L2?
Model: X440-24t
View: 15.2.1.5

Thank you

Hi Felipe,

The configuration for alternate path should be as follows:

Sede:

create vlan ISC2 tag 20
config ISC2 add ports 1 tagged
config ISC2 ipaddress 1.1.1.1/30
configure mlag peer alternate ipaddress 1.1.1.2 vr vr-default

Garagem:

create vlan ISC2 tag 20
config ISC2 add ports 1 tagged
config ISC2 ipaddress 1.1.1.2/30
configure mlag peer alternate ipaddress 1.1.1.1 vr vr-default

Extreme Morro Cristo:

create vlan ISC2 tag 20
config ISC2 add ports 1 tagged

Since the alternate path will cross 2 ports of the same LAG (through "Extreme Morro Cristo" switch), I'm not sure if that works. You can ping 1.1.1.2 from Sede switch and confirm if the communication is working.

Hi Henrique,
Thank you for the tip!

Performed a lab on the item that you sent me and is working, however I have some questions:

Station occurring losses of packages, about 20x1.

This architecture is redundancy or balancing? How to check the traffic on each side of the network?

Hi Henrique,

See if this right. It would be just that?
For not work.

Hi Felipe,

It's not a new MLAG peer. It's a 2nd health-check ISC vlan/ip.

Is case of a link fail between MLAG peers (Sede and Garagem), a 2nd health-check ISC vlan/ip (let's say "ISC2" vlan) will be used to check and assure both peers can still communicate and sync FDB tables till the main ISC link is restored.

This ISC2 vlan would be using the physical link through "Extreme Morro Cristo" switch as follows:

- Sede port 1 (ip 1.1.1.1/30)
- Garagem port 1 (ip 1.1.1.2/30)
- Extreme Morro Cristo ports 1 and 2 (no ipaddress)

Therefore no additional physical link is needed.

Usually this solution uses the "Mgmt" vlan as the 2nd path (new physical link is needed).

However, I believe that the above configuration might help.

That should be validated first.

New MLAG peer? As will be held this check?
