clear ip lisp map-cache

To clear the Locator/ID Separation Protocol (LISP) map cache, use the clear ip lisp map-cache command in privilege EXEC mode.

clear ip lisp map-cache [EID-prefix/ prefix-length]

Syntax Description


`EID-prefix/prefix-length`	(Optional) IPv4 endpoint identifier (EID) prefix to clear from LISP map cache

Command Modes

Privileged EXEC (#)

Release	Modification
15.1(1)XB	This command was introduced.
Cisco IOS XE Release XA	This command was integrated into Cisco IOS XE Release 2.5.1XA.
Cisco IOS XE Release 3.3.0S	This command was integrated into Cisco IOS XE Release 3.3.0S.
15.1(4)M	This command was integrated into Cisco IOS Release15.1(4)M.

Usage Guidelines

The clear ip lisp map-cache command removes all IPv4 dynamic LISP map-cache entries stored by the router. When an optional IPv4 EID prefix is added to the command, only that IPv4 EID prefix is cleared from the LISP map-cache.

Examples

The following example shows how to display all LISP map-cache entries and then clear the LISP map cache for the IPv4 EID prefix 172.16.10.0/24.


Router# show ip lisp map-cache
LISP IPv4 Mapping Cache, 2 entries

clear ip lisp route-import

To clear the current IPv4 routing information base (RIB) routes imported into Locator ID Separation Protocol (LISP), use the clear ip lisp route-import command in privilege EXEC mode.

clear ip lisp route-import [eid-table vrf vrf-name|instance-id iid]

Syntax Description


eid-table vrf `vrf-name`	(Optional) Clear the referenced EID table.
instance-id `iid`	(Optional) Clears the referenced instance ID.

Release	Modification
15.1(4)XB5	This command was introduced.
15.2(3)T	This command was integrated into Cisco IOS Release 15.2(3)T.
Cisco IOS XE Release 3.6S	This command was integrated into Cisco IOS XE Release 3.6S.

Usage Guidelines

The clear ip lisp route-import command operates differently from other clear commands. Most clear commands remove the respective entries or counters only.

However, when the clear ip lisp route-import command is entered, all route-import routes are marked stale and then re-evaluated according to the ip lisp route-import command and remaining stale routes are removed. Thus, entering the clear ip lisp route-import command may or may not result in changes to the imported routes. The show ip lisp route-import command provides a listing of the current route imports.

To restrict the clear functions to a specific EID table, use the eid-table vrf vrf-name keyword and argument. To restrict the clear functions to a specific LISP instance ID, use the instance-id iid keyword and argument.

Examples

The following example shows all IPv4 LISP route-import entries using the show ip lisp route-import command and then clears the IPv4 LISP route-import entries. The debug lisp control-plane rib-rloc-watch command is enabled to indicate the effect of using the clear ip lisp route-import command.


Router# debug lisp control-plane rib-rloc-watch
LISP control plane RIB RLOC watch debugging is on
Router# show ip lisp route-import

clear lisp ddt

To clear the DDT referral cache that is stored on a DDT-enabled map resolver, use the clear lisp ddt command in privileged EXEC mode.

clear lisp ddt referral-cache [instance-id iid | eid | statistics]

Syntax Description

Command History


Release	Modification
15.3(1)T	This command was introduced.
Cisco IOS XE Release 3.8S	This command was integrated into Cisco IOS XE Release 3.8S.

Usage Guidelines

Use this command to clear the referral cache on a DDT map resolver.

A DDT map resolver uses an iterative process of following referrals to find the correct ETR to answer a map request; this requires a DDT map resolver to maintain additional state: a map-referral cache and a lookup queue of map requests that are going through the iterative referral process. The clear lisp ddt command clears the contents of the map-referral cache.

When the clear lisp ddt command is specified using the optional eid entry, the single referral cache entry eid is removed.

When the clear lisp ddt command is specified using the optional instance-id iid keyword, all referral cache entries related to that instance ID are removed. When the clear lisp ddt command is specified using the optional instance-id iid keyword, the single referral cache entry eid within instance-id iid is removed.

Examples

The following example clears the LISP DDT referral cache using the clear lisp ddt command, and then displays the output of show lisp ddt command:

Device> enable
Device# clear lisp ddt referral-cache
Device# show lisp ddt referral-cache
LISP-DDT Referral Cache in VRF "default", 0 entries

Related Commands


Command	Description
ddt	Configures a device to enable LISP DDT functionality.
show lisp ddt	Displays the configured LISP DDT root(s) and/or DDT delegation nodes on a device enabled for LISP DDT.

clear lisp site

To clear the registration data for the specified Locator/ID Separation Protocol (LISP) site, use the clear lisp site command in privilege EXEC mode

clear lisp site {EID-prefix/ prefix-length | site-name}

Syntax Description


`EID-prefix/prefix-length`	IPv4 or IPv6 endpoint identifier (EID) prefix configured on any site for the LISP to clear.
`site-name`	LISP site for which registration data is to be cleared.

Cisco IOS XE Release 3.3.0S	This command was integrated into Cisco IOS XE Release 3.3.0S
15.1(4)M	This command was integrated into Cisco IOS Release 15.1(4)M

Usage Guidelines

On a LISP Map-Server only, the clear lisp site command clears the registration data for the specified LISP site. When the EID-prefix argument in the command, the EID-prefix registration data is cleared from the site containing that EID prefix. If the site is active, the EID prefix will return when the site next registers. When the site-name form of the command is used, all site-specific registration information for the specified site is cleared. If the site is active, the entire site will return when the site next registers.

The registration status of LISP sites is displayed using the show lisp site command.

Examples

The following example shows how to clear the LISP registration data for the LISP site called Site1-xtr.


Map-Server# show lisp site name site1-xtr
Site name: site1-xtr
Description: LISP Site 1
Allowed configured locators: any
Allowed EID-prefixes:
