To configure the Border Gateway Protocol (BGP) on a Locator/ID Separation Protocol (LISP) Map Server to redistribute and advertise endpoint identifier (EID) prefixes from registered LISP sites, use the redistribute lisp route-map command. To remove the configuration, use the no form of this command.

Syntax Description

Command Default

None

Command Modes

Usage Guidelines

When a Map Server registers LISP sites, the EID prefixes from these registered LISP sites are advertised through BGP into the virtual routing and forwarding (VRF) instance that is used by the Locator/ID Separation Protocol Alternative Topology (LISP-ALT). This action can be accomplished by using the redistribute lisp route-map command.

Only after an Egress Tunnel Router (ETR) successfully registers through the Map-Registration process, the EID prefixes from that LISP site are advertised in the URIB or U6RIB by the LISP process. BGP then redistribute the EID prefixes, according to the route-map rules, into the LISP-ALT.

Note	We recommend that you use the route-tag under the eid-prefix command to simplify redistributing EID prefixes into BGP.

You must connect the Map Server to the LISP-ALT. For more information, see the ip lisp alt-vrf and ipv6 lisp alt-vrf command.

This command does not require a license.

To configure the Locator Separation Protocol (LISP) Virtual Machine (VM) switch to register the dynamic endpoint identifier (EID) prefix from the database-mapping dynamic-EID subcommand rather than a more-specific host-EID, use the optional register-database-mapping command. To remove this optional functionality, use the no form of this command.

Syntax Description

This command has no arguments or keywords.

Command Default

More-specific (host-EID) prefix is registered with the configured Map Server.

Command Modes

Dynamic-EID configuration mode

Command History

Usage Guidelines

Use the register-database-mapping command to cause the LISP VM switch to register the dynamic EID prefix from the database-mapping dynamic-EID subcommand rather than (more-specific) dynamic host-EIDs to the Map Server. By default, host-based dynamic-EIDs are registered to the Map Server.

You can use the register-database-mapping command to support cloud applications. When a dynamic EID matches the dynamic EID prefix from the database-mapping dynamic-EID subcommand, the entire dynamic-EID prefix is registered and all endpoint identifiers (EIDs) are moved to the new locator set.

This command does not require a license.

To configure an optional endpoint identifier (EID) or list of EIDs to be considered as roaming dynamic EIDs, use the roaming-eid-prefix command. To remove this optional functionality, use the no form of this command.

Syntax Description

Command Default

Specific (host-EID) prefixes within the dynamic-EID prefix range specified in the database-mapping dynamic-EID subcommand are individually registered with the configured Map Server.

Command Modes

Dynamic-EID configuration mode

Command History

Usage Guidelines

When an EID is detected to be a candidate for dynamic-EID roaming and the optional roaming-eid-prefix command is used, the EID must be covered by the roaming-EID prefix entry in order to be discovered. The EID prefix listed in a database-mapping entry within the lisp dynamic-eid policy is registered with the Map Server specified in the map-server command. That is, the roaming-eid-prefix command restricts the discovery of LISP virtual machine (VM) Mobility (dynamic-EID roaming) for initiating Map-Server registration.

Note	Without this command, any EID within the EID prefix range configured through the database-mapping entry is discovered and registered.

The EID referenced by the roaming-eid-prefix command can be either an IPv4 or IPv6 address in the EID space.
