This command lists a summary of the configuration and status for the active IPv6 routing protocols. The command lists routing protocols that are configured and enabled. If a protocol is selected on the command line, the display is limited to that protocol.
| Format | show ipv6 protocols [bgp|ospf] |
| 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 a 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. |
| OSPFv3 Section: | |
| Routing Protocol | OSPFv3. |
| Router ID | The router ID configured for OSPFv3. |
| OSPF Admin Mode | Whether OSPF is enabled or disabled globally. |
| Maximum Paths | The maximum number of next hops in an OSPF route. |
| 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. |
