					<description><![CDATA[A BGP “zombie” is essentially a fancy name for a route that has become stuck in the Default-Free Zone (DFZ) of the Internet, potentially due to a missed or lost prefix withdrawal. 

In this post, we will walk through some situations where BGP zombies are more likely to rise from the dead and wreak havoc, how excessive path hunting can contribute to longer periods of impact, and some recommendations and follow-ups we have to put together to make them less likely.]]></description>
