Hi All,

Receiving this error

Cisco's answer...


 When a Cisco 10720 Internet Router loads a large routing table, the
following error message may appear:
%GENERAL-3-EREVENT: HWCEF: Failed to alloc Mtrie HW node

This means that the Mtrie IP lookup algorithm used in Cisco Express
Forwarding (CEF) failed to allocate sufficient memory. This error
happens when a full Internet table that consists of approximately 100K
or more of sparsely distributed routes is added to the hardware
forwarding table.

Workaround: There is no known workaroun 

Any ideas what I can do, without reloading this router??

Christian
