BGP: amsix configuration guide

Tue Apr 15, 2025 3:45 pm

It seems like current configuration guide on AMS-IX website for mikrotik devices have a plenty of mistakes like recommendation to set interfacing LAGs into disabled state to disable proxy-arp etc.
https://www.ams-ix.net/ams/documentatio ... n-20313799

It would be great to have some clarity how to configure correctly these routers to be compliant with IXPs like amsix.

so mainly wondering whats the correct way to disable proxy-arp to be compliant with ixp without disabling my interface?

What's, in your opinion, wrong with disabling Proxy ARP on an IXP interface?

In general:

- Disable all layer2 Protos (LLDP, CDP etc)
- Disable Spanning Tree
- Disable Multicast things (OSPF, ..)
- Only send traffic originating from 1 mac...

/interface/bonding/ set LAG2 arp=proxy-arp disabled=yes
afaik this will disable the whole LAG2?

Disabling the interface is probably wrong. Disabling ProxyARP is not.

/interface/bonding/ set LAG2 arp=proxy-arp disabled=yes
This is just WRONG!!!
They want to disable proxy arp, not the interface. It means you should use "arp=enabled".
