A keyword after which follows the four metric components (bandwidth, delay, reliability, link load), plus the MTU associated with the route. [EIGRP]
If redistributing from OSPF, this keyword lets you match internal OSPF routes, external (by type), and NSSA external routes, essentially filtering which routes are redistributed. [EIGRP]
Assigns a unitless integer value to the routes redistributed by this command—tags which can be later matched by other routers using a route-map [EIGRP, OSPF]
Apply the logic in the referenced route-map to filter routes, set metrics, and set route tags. [EIGRP, OSPF]
Defines the cost metric assigned to routes redistributed by this command, unless overridden by a referenced route map. [OSPF]
Defines the external metric type for the routes redistributed by this command: 1 (E1 routes) or 2 (E2 routes). [OSPF]
If redistributing from another OSPF process, this keyword lets you match internal OSPF routes, external (by type), and NSSA external routes, essentially filtering which routes are redistributed. [OSPF]
Redistribute subnets of classful networks. Without this parameter, only routes for classful networks are redistributed. [OSPF-unique]
If redistributing a routing protocol that uses a process-id or ASN on the router global config command, use this parameter to refer to that process or ASN value.
The source of routing information. Includes RIP, OSPF, EIGRP, IS-IS, BGP, connected, and static.
OSPF Redistribution with Minimal Parameters
When taking from BGP, use a default metric of 1.
When taking from another OSPF process, take the source route’s metric.
When taking from all other sources, use a default metric of 20.
Create a Type 5 LSA for each redistributed route (external) if not inside an NSSA area; create a Type 7 LSA if inside an NSSA area.
Use external metric type 2.
Redistribute only routes of classful (class A, B, and C) networks, and not routes for subnets.
Default if no metric configuration exists
Cost 1 for routes learned from BGP.
If redistributed from another OSPF process, use the source route’s OSPF cost.
Cost 20 for all other route sources.
Setting the default for all redistribute commands
The default-metriccost OSPF subcommand.
Setting the metric for one route source
The metriccost parameters on the redistribute command.
Setting different metrics for routes learned from a single source
Use the route-map parameter on the redistribute command.
