[AusNOG] Dealing with global route views

[Nathan Brookfield]

Does the upstream in question support BGP Action communities to stop advertising routes through the impacted path?

Hi All,

Coming to the end of a couple of long weeks, and brain is a bit fried.

For the last few days we've had issues where one or other of our two primary internal upstreams has had DOS attacks affecting their connectivity on foreign soil (i.e. connectivity via Level 3 is borked, or connectivity via he.net<http://he.net> is borked), which has adversely affected our ability to reach certain parts of the world, and conversely their ability to reach us.

In both cases we don't really want to drop either transit provider completely as the domestic performance we get from them both is good.

On another day my brain might see this really clearly, but just can't get my head into it for now.

Can we:

a) adjust our internal preferences accurately enough to influence our outbound traffic to prefer one or the other in particular, operator driven scenarios
b) influence our rest of the world traffic to avoid he.net<http://he.net> or level 3

… and how?

I believe one of our upstreams (Vocus) will honour some "do not advertise here" communities (but I don't know where the list is), but I suspect the other (PIPE) will not?

Thanks,
Andrew
