    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.

    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
