1-5When the primary route recovers, the route selection process is performed again and the primary routeis selected again to forward packets.Routing Information SharingAs different routing protocols use different algorithms to calculate routes, they may discover differentroutes. In a large network with multiple routing protocols, it is required for routing protocols to share theirrouting information. Each routing protocol shares routing information discovered by other routingprotocols through a route redistribution mechanism.Displaying and Maintaining a Routing TableTo do… Use the command… RemarksDisplay brief information about arouting tabledisplay ip routing-table [ | { begin | exclude |include } regular-expression ]Display detailed information abouta routing table display ip routing-table verboseDisplay information about routespermitted by a basic ACLdisplay ip routing-table acl acl-number[ verbose ]Display information about routespermitted by a prefix listdisplay ip routing-table ip-prefixip-prefix-name [ verbose ]Display routes to a specifieddestinationdisplay ip routing-table ip-address [ mask |mask-length ] [ longer-match ] [ verbose ]Display routes to specifieddestinationsdisplay ip routing-table ip-address1 { mask1 |mask-length1 } ip-address2 { mask2 |mask-length2 } [ verbose ]Display routes discovered by arouting protocoldisplay ip routing-table protocol protocol[ inactive | verbose ]Display the tree-structured routingtable information display ip routing-table radixDisplay statistics about a routingtable display ip routing-table statisticsAvailable in any viewClear statistics about a routingtablereset ip routing-table statistics protocol { all |protocol } Available in user view
