Description: The maximum number of static routes and routes redistributed from other protocols that DC-ISIS will accept.

The action that DC-ISIS will take when the maximum is exceeded is controlled by isisSysMaxExternalRoutesAction.

0xFFFFFFFF is a special value indicating that the threshold is infinite.

What is isisSysMaxExternalRoutes?

Caps the number of static routes and routes redistributed from other protocols that DC-ISIS will accept, defaulting to 0xFFFFFFFF (infinite); what happens when the limit is exceeded is controlled by isisSysMaxExternalRoutesAction. An admin sets a finite cap here to protect LSP size and router resources from an uncontrolled redistribution leak from another protocol flooding IS-IS with external routes.
