Prefix Advertisement
This alarm rule detects when a prefix is advertised and reports if it exceeds the threshold trigger.
 Note |
It is useful to know which of your peers may be doing something wrong (leaking route information or having some type of misconfiguration) so that you can address the problem right away. A My Peers rule is available for this alarm with certain Crosswork Cloud subscriptions. The My Peers option follows BGP updates only from your peers, whereas All Peers follow BGP updates from your peers and global peers. To configure this option, see Add Crosswork Cloud Network Insights Policies. |
