Conditional advertisements?

That way you don’t advertise anything to Telstra until you stop receiving
routes from primary ISP for example.

>>Hey all,
>>
>>We currently utilise Telstra Internet Direct services for our primary
>>inbound for AS38236, I would like to move to using Telstra as the least
>>preferred and swap to another provider for inbound.
>>
>>When I tested the swap, the majority of domestic looking glasses were
>>confirming inbound through our preferred inbound. However Telstra always
>>seems to prefer their own routes instead of peer learnt; even after
>>setting either as-prepend or MED. A Telstra engineer confirmed this.
>>
>>My question is pretty much is there any other way to steer inbound
>>traffic to us through Telstra? (without grabbing a /23 and advertising
>>more specific 2 x /24s or using communities, which Telstra doesn't
>>support)
>>
>>The only other alternative would be to swap providers at our DR site, and
>>we originally had issues getting a service installed there.
>>
>>Does anyone also know if this is the default behaviour through Telstra
>>Wholesale Internet?
>>
