maximum prefix maximum [mid-threshold]

no maximum prefix

Syntax Description


`maximum`	Maximum number of prefixes allowed in the VRF instance. Range is 32 to 2000000.
`mid-threshold`	(Optional) Integer specifying at what percentage of the `maximum` argument value the software starts to generate a Simple Network Management Protocol (SNMP) trap. Range is 1 to 100.

Command Default

No default behavior or values

Command Modes

Global VRF address family configuration

Command History


Release	Modification
Release 3.3.0	This command was introduced.

Usage Guidelines

To use this command, you must be in a user group associated with a task group that includes appropriate task IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator for assistance.

You can set a value for the mid-threshold argument which is a hard limit. Routes will be blocked after the set mid-threshold value is reached.

Use the maximum prefix command to configure a maximum number of prefixes that a VRF instance is allowed to receive.

Task ID


Task ID	Operations
rib	read, write

Examples

The following example shows how to set the maximum number of prefixes allowed to 1000:

if the number of routes is above the threshold when"maximum prefix" configuration has been committed
if the number routes reaches the configured "maximum prefix" values for the VRF

rump always-replicate [access-list]

Release 3.9.0	This command was introduced.

Usage Guidelines

To use this command, you must be in a user group associated with a task group that includes appropriate task IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator for assistance.

Configuring the rump always-replicate command allows routers in a network to be upgraded to multitopology routing gradually without a flag day where all routers need to be configured at the same time without major service disruption. When rump always-replicate is configured, replicated routes are added into the muRIB with the lowest admin distance. So if protocols are populating the muRIB, they continue to do so. For the same route, protocol routes win over replicated routes because of higher admin distance.

If an unwanted more specific route comes from the uRIB, optionally provide an access list through which the replicated routes are run. If the route passes the access list, the route is replicated by RUMP.

Usage Guidelines

To use this command, you must be in a user group associated with a task group that includes appropriate task IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator for assistance.

Use the show rib statistics command to display RIB statistics. The statistics include requests sent from the clients to the RIB and the information redistributed to the client.

RIB maintains counters for all requests sent from a client including:

Route operations
Table registrations
Next-hop registrations
Redistribution registrations
Attribute registrations
Synchronization completion

RIB also maintains the results of the requests.

When you specify that you want information about a particular network, more detailed statistics are displayed. The following is sample output from the show route command when entered with an IP address:


 RP/0/RP0/CPU0:router# show route 10.0.0.0
  
  Routing entry for 10.0.0.0/16

    Routing Descriptor Blocks
      directly connected, via GigabitEthernet0/0/0/0
        Route metric is 0
    No advertising protos.

Intermediate System-to-Intermediate System (IS-IS) includes an IP address typed length value (TLV) in its link-state packet (LSP) that helps identify the node injecting the route into the network. The IS-IS node uses one of its own interface addresses in this TLV. A loopback address is preferred among interfaces configured under IS-IS. When other networking devices calculate IP routes, they can store the IP address as the originator address with each route in the routing table.

The following example shows the output from the show route command for a specific IP address on a router configured with IS-IS. Each path that is shown under the Routing Descriptor Blocks report displays two IP addresses. The first address (10.0.0.9) is the next-hop address; the second is the originator IP address from the advertising IS-IS router.


 RP/0/RP0/CPU0:router# show route 10.0.0.1

Usage Guidelines

To use this command, you must be in a user group associated with a task group that includes appropriate task IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator for assistance.

RIB quarantining detects mutually recursive routes and quarantines the last route that actually completes the mutual recursion. The quarantined route is periodically evaluated to see if the mutual recursion has gone away. If the recursion still exists, the route remains quarantined. If the recursion has gone away, the route is released from quarantine.

Use the show route quarantined command to display mutually recursive (looping) routes.

The topology keyword must be accompanied by the ipv4 multicast keywords, except when the afi-all keyword or the safi-all keyword is specified.

Release	Modification
Release 2.0	This command was introduced.
Release 3.2	The afi-all and safi-all keywords were added.
Release 3.3.0	The vrf `vrf-name` keyword and argument were added.

Usage Guidelines

To use this command, you must be in a user group associated with a task group that includes appropriate task IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator for assistance.

Use the show route resolving-next-hop command to perform a recursive route lookup on the supplied destination address and return information on the next immediate router (next hop) to the destination.

The topology keyword must be accompanied by the ipv4 multicast keywords, except when the afi-all keyword or the safi-all keyword is specified.

Usage Guidelines

To use this command, you must be in a user group associated with a task group that includes appropriate task IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator for assistance.

Use the show route summary command to display information about routes in the routing information base.

When a route summary is needed frequently—for instance, in a polling situation—use the show route summary command without the detail keyword. The detail keyword is used less frequently for verification purposes, because it is much more expensive (in bandwidth), requiring a scan of the entire routing database.

The topology keyword must be accompanied by the ipv4 multicast keywords, except when the afi-all keyword or the safi-all keyword is specified.
