Abstract:
1. A method of adjusting route metrics in a data packet router, comprising the steps of: determining if virtual routing redundancy protocol (VRRP) routing is enabled on the router; determining, responsive to VRRP being enabled on the router, if the router is a backup VRRP router; setting on the router, responsive to VRRP being enabled on the router and the router being a VRRP backup router, a pointer in a routing information base (RIB) entry for an interface of the router to point to a first metric entry of a management information base (MIB) object corresponding to the interface; and setting on the router, responsive to VRRP being enabled on the router and the router not being a VRRP backup router, the pointer to point to a second metric entry of the MIB object, wherein the second metric entry has a value that is different than a value of the first metric entry.
