Cisco Nexus 7000 Series LISP Commands
allowed-locator
LSP-2
Cisco Nexus 7000 Series NX-OS LISP Command Reference
allowed-locator
To configure a list of locators that are allowed in a Map-Register message sent by an egress tunnel router
(ETR) when registering to the Map Server, use the allowed-locator command. To remove the locators,
use the no form of this command.
allowed-locator {rloc1 [rloc2 [rloc3 [rloc4]]]}
Syntax Description
Defaults None
Command Modes LISP site configuration mode
SupportedUserRoles network-admin
vdc-admin
Command History
Usage Guidelines When a LISP ETR registers with a Map Server, it sends a Map-Register message that contains, one or
more EID-prefixes and routing locators that the ETR is configured to use. After verifying the
authentication data, the Map Server checks the EID-prefixes against those configured on the
Map-Server. If they agree, the Map Register is accepted and the ETR registration is completed.
You can constraint the Map Server default behavior so that the ETR can only register using specific
routing locators. To enable this functionality, enter the allowed-locator command in LISP site
configuration mode. The Map-Register message from the ETR must contain the same locators that are
listed in the Map-Server LISP site configuration. If the list in the Map Register does not match the one
configured on the Map Server, the Map-Register message is not accepted and the ETR is not registered.
You can configure up to four IPv4 or IPv6 routing locators.
Note When you configure allowed locators, an exact match for all locators or a subset of all locators listed on
the Map Server within the LISP site configuration must also appear in the Map-Register message sent
by the ETR for it to be accepted.
This command does not require a license.
rloc1 IPv4 or IPv6 Routing Locator (RLOC) allowed within the Map-Registration
message.
rloc2,rloc3,rloc14 Additional IPv4 or IPv6 RLOCs allowed within the Map-Registration message.

5.0(1.13) This command was introduced.

Examples This example shows how to configure the LISP site named Customer-1 and enter the site command
mode. This example also shows the IPv4 address 172.16.1.1 and the IPv6 address 2001:db8:bb::1 are
configured as allowable locators for the LISP site Customer-1. When Customer-1 registers with this Map
Server, at least one or both of the configured locators must be included in the Map Registration for the
site to register.

LSP-4
Cisco Nexus 7000 Series NX-OS LISP Command Reference
authentication-key
To configure the password used to create the SHA-1 HMAC hash for authenticating the Map-Register
message sent by an egress tunnel router (ETR) when registering to the Map-Server, use the
authentication-key command. To remove the password, use the no form of this command.
authentication-key key-type password
no authentication-key key-type password
Syntax Description
Defaults None
Command Modes LISP site configuration mode
SupportedUserRoles network-admin
vdc-admin
Command History
Usage Guidelines When a Locator/ID Separation Protocol (LISP) ETR registers with a Map-Server, the Map Server must
already have been configured with certain LISP site attributes that match the ETR attributes. These
attributes include a shared password that is used to create the SHA-1 HMAC hash that the Map Server
uses to validate the authentication data in the Map-Register message. On the ETR, this password is
configured by using the ip lisp etr map-server and ipv6 lisp etr map-server command.
On the Map Server, the password is configured as part of the lisp site configuration process. To enter the
LISP site password, enter the authentication-key command in LISP site configuration mode. You can
enter the SHA-1 HMAC password in unencrypted (cleartext) form or encrypted form. To enter an
unencrypted password, specify a key-type value of 0. To enter a 3DES-encrypted password, specify a
key-type value of 3. To enter a Cisco-encrypted password, specify a key-type value of 7.
Caution Map-Server authentication keys entered in cleartext form automatically are converted to Type 3
(encrypted) form.
key-type Key type that the following SHA-1 password is encoded using Type (0) indicates
that a cleartext password follows. Type (3) indicates that a 3DES encrypted key
follows, and Type (7) indicates that a Cisco Type 7 encrypted password follows.
password Password used to create the SHA-1 HMAC hash when authenticating the
Map-Register message sent by the ETR.

Note You must configure the Map Server and ETR with matching passwords for the Map-Registration process
to successfully complete. When a LISP site successfully completes the Map-Registration process, its
attributes are displayed by using the show lisp site command. If the Map-Registration process is
unsuccessful, the site does not be display.
This command does not require a license.
Examples This example shows how to configure the LISP site named Customer-1, enter the site command mode,
and enter the shared password:
switch# configuration terminal
switch(config)# lisp site Customer-1

clear ip lisp data-cache
LSP-6
Cisco Nexus 7000 Series NX-OS LISP Command Reference
clear ip lisp data-cache
To clear the LISP IPv4 data-cache, use the clear ip lisp data-cache command.
clear ip lisp data-cache [vrf vrf-name] [EID]
Syntax Description
Defaults None
Command Modes Any command mode
SupportedUserRoles network-admin
vdc-admin
Command History
Usage Guidelines The clear ip lisp data-cache command removes all IPv4 endpoint identifier to Routing Locator
(EID-to-RLOC) mapping in the forwarding data-cache. Data-cache entries are present in two cases only:
when the ip lisp itr send-data-probe command entered, after a data-probe is sent, this data-probe is
stored in the data cache until a Map-Reply is returned, when you enter the ip lisp etr glean-mapping
command, gleaned EID-to-RLOC mapping data is stored in the data cache until the data is verified.
When you use the optional vrf keyword, the data-cache is cleared for the specified VRF. When the EID
option is used, only the EID-to-RLOC mapping for that entry is cleared.
This command does not require a license.
Examples This example shows how to clear the LISP IPv4 data cache:
switch# clear ip lisp data-cache
Related Commands
vrf vrf-name (Optional) Specifies virtual routing and forwarding (VRF) instance with which
to clear the data cache.
EID (Optional) IPv4 EID to clear from LISP data-cache.
Release Modification
5.0(1.13) This command was introduced.
Command Description

stored in the data cache until a Map-Reply is returned, when you enter the ip lisp etr glean-mapping
command, gleaned EID-to-RLOC mapping data is stored in the data cache until the data is verified.
When you use the optional vrf keyword, the data-cache is cleared for the specified VRF. When the EID
option is used, only the EID-to-RLOC mapping for that entry is cleared.
This command does not require a licens.
