• Generate a tag to be added to redistributed routes. CONFIG-ROUTE-MAP mode set automatic-tag • Specify an OSPF area or ISIS level for redistributed routes. CONFIG-ROUTE-MAP mode set level {backbone | level-1 | level-1-2 | level-2 | stub-area} • Specify a value for the BGP route's LOCAL_PREF attribute. CONFIG-ROUTE-MAP mode set local-preference value • Specify a value for redistributed routes. CONFIG-ROUTE-MAP mode set metric {+ | - | metric-value} • Specify an OSPF or ISIS type for redistributed routes. CONFIG-ROUTE-MAP mode set metric-type {external | internal | type-1 | type-2} • Assign an IP address as the route's next hop. CONFIG-ROUTE-MAP mode set next-hop ip-address • Assign an IPv6 address as the route's next hop. CONFIG-ROUTE-MAP mode set ipv6 next-hop ip-address • Assign an ORIGIN attribute. CONFIG-ROUTE-MAP mode set origin {egp | igp | incomplete} • Specify a tag for the redistributed routes. CONFIG-ROUTE-MAP mode set tag tag-value • Specify a value as the route's weight. CONFIG-ROUTE-MAP mode set weight value To create route map instances, use these commands. There is no limit to the number of set commands per route map, but the convention is to keep the number of set filters in a route map low. Set commands do not require a corresponding match command. Configure a Route Map for Route Redistribution Route maps on their own cannot affect traffic and must be included in different commands to affect routing traffic. Route redistribution occurs when Dell EMC Networking OS learns the advertising routes from static or directly connected routes or another routing protocol. Different protocols assign different values to redistributed routes to identify either the routes and their origins. The metric value is the most common attribute that is changed to properly redistribute other routes into a routing protocol. Other attributes that can be changed include the metric type (for example, external and internal route types in OSPF) and route tag. Use the redistribute command in OSPF, RIP, ISIS, and BGP to set some of these attributes for routes that are redistributed into those protocols. Access Control Lists (ACLs) 137
