Monitoring IP Protocols

Purpose

Display detailed information about IP protocols currently configured on the router.

You can use the summary keyword to display only a list of the configured protocols.

Table 22: 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 receives version 1 or 2. If the version is set to RIP2, the router sends and receives 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
