Meaning

Table 20 lists the show ip protocols command output fields.

Table 20: show ip protocols Output Fields

Field Name	Field Description
For BGP:
Redistributing	Protocol to which BGP is redistributing routes
Default local preference	Local preference value
IGP synchronization	Status of IGP synchronization: enabled, disabled
Always compare MED	Status of multiexit discrimination: enabled, disabled
Router flap damping	Status of route dampening: enabled, disabled
Administrative Distance	External, internal, and local administrative distances
Neighbor Address	IP address of the BGP neighbor
Neighbor Incoming/Outgoing update distribute list	Number of the access list for outgoing routes
Neighbor Incoming/Outgoing update prefix list	Number of the prefix list for incoming or outgoing routes
Neighbor Incoming/Outgoing update prefix tree	Number of the prefix tree for incoming or outgoing routes
Neighbor Incoming/Outgoing update filter list	Number of filter list for incoming routes
Routing for Networks	Network for which BGP is currently injecting routes
For IS-IS:
System Id	6-byte value of the system
IS-Type	Routing type of the router: Level 1, Level 2
Distance	Administrative distance for IS-IS learned routes
Address Summarization	Aggregate addresses defined in the routing table for multiple groups of addresses at a given level or routes learned from other routing protocols
Routing for Networks	Network for which IS-IS is currently injecting routes
For OSPF:
Router ID	OSPF process ID for the router
Distance	Administrative distance for OSPF learned routes
Redistributing	Protocol to which OSPF is redistributing routes
Address Summarization	Aggregate addresses defined in the routing table for multiple groups of addresses at a given level or routes learned from other routing protocols
Routing for Networks	Network for which OSPF is currently injecting routes
For RIP:
Router Administrative State	RIP protocol state. Enable means that the interface is allowed to send and receive updates. Disable means that the interface, if it is configured, is not enabled to run yet.
System version	RIP versions allowed for sending and receiving RIP updates. The router version is currently set to RIP1, which sends RIP version 1 but will receive version 1 or 2. If the version is set to RIP2, the router will send and receive version 2 only. The default is configured for RIP1.
Update interval	Current setting of the update timer (in seconds)
Invalid after	Current setting of the invalid timer (in seconds)
hold down time	Current setting of the hold down timer (in seconds)
flushed interval	Current setting of the flush timer (in seconds)
Filter applied to outgoing route update	Access list applied to outgoing RIP route updates
Filter applied to incoming route update	Access list applied to incoming RIP route updates
Global route map	Route map that specifies all RIP interfaces on the router
Distance	Value added to RIP routes added to the IP routing table; the default is 120.
Interface	Interface type on which RIP protocol is running
Redistributing	Protocol to which RIP is redistributing routes
Routing for Networks	Network for which RIP is currently injecting routes
