I support this course of action. background: Some in the working group might wonder why Large should change instead of Huawei. Huawei routers are treating routes with Large BGP Communities as "withdraw", which makes Large BGP Communities deployments suffer. Large BGP Communities users become unreachable on attribute 30. Had the squatting resulted in Huawei routers crashing or some other form of damage on the Huawei side, the onus would be on Huawei users. This is not the case unfortunatly. There are no winners if either side holds their ground and remains on the codepoint. For Large BGP Communities it is still early enough to update the implementations. Changing the Large BGP Communities path attribute value is a risk adverse strategy. Kind regards, Job
