Member may puke L2 loop to IXP, you must have some channel to deal with your customers.
First, mac filters. Second, if someone l2 loops and it causes problems because of hardware failure on our side, we reserve the right to pull connectivity: https://www.inex.ie/technical/maintenance
In the case of emergencies, INEX reserves the right to perform critical maintenance on a 24x7x365 basis without prior notification to INEX members. Emergencies are defined as situations where: [...] - member port misconfiguration or hardware/software bug causes loss of service or down-time for other INEX members, in the potential situation where this is not prevented by INEX port security measures
Fortunately, it's only rarely that this happens. Third, someone puking an l2 loop to the IXP is a problem which may affect the ixp infrastructure. This is not the case when people muck up their MTU config. There is a demarcation line here: one is an IXP problem; the other is not. Nick
