This command lists a summary of the configuration and status for each unicast routing protocol. The command lists routing protocols which are configured and enabled. If a protocol is selected on the command line, the display will be limited to that protocol. If no virtual router is specified, the configuration and status for the default router are displayed.

| Mode | Privileged EXEC |
| Parameter | Description |
|---|---|
| BGP Section: | |
| Routing Protocol | BGP. |
| Router ID | The router ID configured for BGP. |
| Local AS Number | The AS number that the local router is in. |
| BGP Admin Mode | Whether BGP is globally enabled or disabled. |
| Maximum Paths | The maximum number of next hops in an internal or external BGP route. |
| Always Compare MED | Whether BGP is configured to compare the MEDs for routes received from peers in different ASs. |
| Maximum AS Path Length | Limit on the length of AS paths that BGP accepts from its neighbors. |
| Fast Internal Failover | Whether BGP immediately brings down an iBGP adjacency if the routing table manager reports that the peer address is no longer reachable. |
| Fast External Failover | Whether BGP immediately brings down an eBGP adjacency if the link to the neighbor goes down. |
| Distance | The default administrative distance (or route preference) for external, internal, and locally-originated BGP routes. The table that follows lists ranges of neighbor addresses that have been configured to override the default distance with a neighbor-specific distance. If a neighbor‘s address falls within one of these ranges, routes from that neighbor are assigned the configured distance. If a prefix list is configured, then the distance is only assigned to prefixes from the neighbor that are permitted by the prefix list. |
| Redistribution | A table showing information for each source protocol (connected, static, rip, and ospf). For each of these sources the distribution list and route-map are shown, as well as the configured metric. Fields which are not configured are left blank. For ospf, an additional line shows the configured ospf match parameters. |
| Prefix List In | The global prefix list used to filter inbound routes from all neighbors. |
| Prefix List Out | The global prefix list used to filter outbound routes to all neighbors. |
| Networks Originated | The set of networks originated through a network command. Those networks that are actually advertised to neighbors are marked “active.” |
| Neighbors | A list of configured neighbors and the inbound and outbound policies configured for each. |
| OSPFv2 Section: | |
| Routing Protocol | OSPFv2. |
| Router ID | The router ID configured for OSPFv2. |
| OSPF Admin Mode | Whether OSPF is enabled or disabled globally. |
| Maximum Paths | The maximum number of next hops in an OSPF route. |
| Routing for Networks | The address ranges configured with an OSPF network command. |
| Distance | The administrative distance (or “route preference”) for intra-area, inter-area, and external routes. |
| Default Route Advertise | Whether OSPF is configured to originate a default route. |
| Always | Whether default advertisement depends on having a default route in the common routing table. |
| Metric | The metric configured to be advertised with the default route. |
| Metric Type | The metric type for the default route. |
| Redist Source | A type of routes that OSPF is redistributing. |
| Metric | The metric to advertise for redistributed routes of this type. |
| Metric Type | The metric type to advertise for redistributed routes of this type. |
| Subnets | Whether OSPF redistributes subnets of classful addresses, or only classful prefixes. |
| Dist List | A distribute list used to filter routes of this type. Only routes that pass the distribute list are redistributed. |
| Number of Active Areas | The number of OSPF areas with at least one interface running on this router. Also broken down by area type. |
| ABR Status | Whether the router is currently an area border router. A router is an area border router if it has interfaces that are up in more than one area. |
| ASBR Status | Whether the router is an autonomous system boundary router. The router is an ASBR if it is redistributing any routes or originating a default route. |
| RIP Section | |
| RIP Admin Mode | Whether RIP (Routing Information Protocol) is globally enabled. |
| Split Horizon Mode | Whether RIP advertises routes on the interface where they were received. |
| Default Metric | The metric assigned to redistributed routes. |
| Default Route Advertise | Whether this router is originating a default route. |
| Distance | The administrative distance for RIP routes. |
| Redistribution | A table showing information for each source protocol (connected, static, bgp, and ospf). For each of these source the distribution list and metric are shown. Fields which are not configured are left blank. For ospf, configured ospf match parameters are also shown. |
| Interface | The interfaces where RIP is enabled and the version sent and accepted on each interface. |
The following example shows CLI display output for the command.
