This command places the router in address family configuration mode (prompt: config-router-af), from which you can configure routing sessions that support Multicast VPN provisioning for IPv4 or IPv6.

To create a summary address in a Border Gateway Protocol (BGP) routing table, use the aggregate-address command. To remove the summary address, use the no form of this command.

Command Default

The atomic aggregate attribute is set automatically when an aggregate route is created with this command unless the as-set keyword is specified.

Command Modes

Address-family configuration mode

Neighbor address-family configuration mode

Router BGP configuration mode

Usage Guidelines

You can implement aggregate routing in BGP and mBGP either by redistributing an aggregate route into BGP or mBGP, or by using the conditional aggregate routing feature.

Using the aggregate-address command with no keywords will create an aggregate entry in the BGP or mBGP routing table if any more-specific BGP or mBGP routes are available that fall within the specified range. (A longer prefix which matches the aggregate must exist in the RIB.) The aggregate route will be advertised as coming from your autonomous system and will have the atomic aggregate attribute set to show that information might be missing. (By default, the atomic aggregate attribute is set unless you specify the as-set keyword.)

Using the as-set keyword creates an aggregate entry using the same rules that the command follows without this keyword, but the path advertised for this route will be an AS_SET consisting of all elements contained in all paths that are being summarized. Do not use this form of the aggregate-address command when aggregating many paths, because this route must be continually withdrawn and updated as autonomous system path reachability information for the summarized routes changes.

Using the summary-only keyword not only creates the aggregate route (for example, 192.*.*.*) but also suppresses advertisements of more-specific routes to all neighbors. If you want to suppress only advertisements to certain neighbors, you may use the neighbor distribute-list command, with caution. If a more-specific route leaks out, all BGP or mBGP routers will prefer that route over the less-specific aggregate you are generating (using longest-match routing).

Using the suppress-map keyword creates the aggregate route but suppresses advertisement of specified routes. You can use the match clauses of route maps to selectively suppress some more-specific routes of the aggregate and leave others unsuppressed. IP access lists and autonomous system path access lists match clauses are supported.

Using the attribute-map keyword allows attributes of the aggregate route to be changed. This form of the aggregate-address command is useful when one of the routes forming the AS_SET is configured with an attribute such as the community no-export attribute, which would prevent the aggregate route from being exported. An attribute map route map can be created to change the aggregate attributes.

This command requires the Enterprise Services license.

To apply a configuration profile to configure hosts, use the apply profile command in global configuration mode. To remove the configuration profile use the no form of this command.

Command Default

The port profile is not applied.

Command Modes

Global configuration (config)

Usage Guidelines

Configuration profiles provide an infrastructure to configure hosts based on a set of user-defined templates. You can define different templates for different types of hosts and enable them appropriately based on an event, such as host discovery. You can apply different profiles to different hosts and apply different values for the configuration for different hosts.

Use the apply profile command to apply a configuration profile on a host.

Use the configure profile command to create a configuration profile and add a parameter list and a parameter-list instance. You can either create one parameterized profile for each host or create one profile with parameterized argument and apply it with host-specific arguments. The parameter-list instance provides the actual values that are added in the configuration profile before the profile is applied. The parameter name in the instance must match the parameter name in the profile.

This command has no arguments or keywords.

Command Default

Layer 2 VFI autodiscovery is disabled.

Command Modes

L2 VFI configuration (config-vfi)

Usage Guidelines

Cisco DFA fabrics communicate to other Cisco DFA fabrics and to the external networks through one or more border leaf switches. If a border leaf does not support Edge Router functionalities, such as Multi Protocol Label Switching or virtual private network, Virtual Private LAN Service (VPLS), or Overlay Transport Virtualization (OTV), a separate Edge Router device pairs with the border leaf switch to enable Layer 3 connectivity to the end points in the same VRF in another fabric. This is called a VRF-lite or CE-PE.

The fabric database auto-pull dci command creates an Edge Router VRF-specific auto configuration on the border leafs or the Edge Router devices or both, and enables Layer 3 connectivity to end points in the same VRF in another fabric or to the outside world (WAN), whether the other fabric is geographically collocated or not.

This command is supported on the border leaf switch in a Edge Router in a VRF-lite or CE-PE solution.

Note	EL2 license is required for fabric forwarding. For GW and auto-config, L3 Base and LAN Enterprise licenses are required with no grace-period for L3 Base.

To configure the mobility domain name, use the fabric database mobility-domain command in global configuration mode. To remove the mobility domain name, use the no form of this command.

Command Default

The mobility domain name is not configured.

Command Modes

Global configuration (config)

Usage Guidelines

Use the fabric database mobility-domain command to configure the mobility domain name that is used to retrieve the profile name and parameters, if the profiles are stored remotely. Profiles stored remotely are indexed by the mobility domain and VLAN pair.

Mobility domain uses only data plane MAC learning as the network auto-configuration trigger.

The specified domain-name must match the mobility domain ID specified in the Cisco Prime DCNM as part of the workload-automation settings. If they do not match, the auto-configuration profile will not be populated with the appropriate parameters (for example, segment-IP or subnet).

Mobility domain requires either 802.1Q trunk header transport or, if an access-port is used, a trunk with a native VLAN and matching allowed VLAN between the host (server) and the leaf switch.

To configure fabric database override network profile name, use the fabric database override-profile command in global configuration mode. To remove the override profile name, use the no form of this command.

Command Default

The profile returned from the Lightweight Directory Access Protocol (LDAP) is honored as part of the auto-configuration trigger.

Command Modes

Global configuration (config)

Usage Guidelines

An example use-case for this command is the usage on a Cisco Nexus 5500 Platform Switch that does not support segment ID. Consequently, the Cisco Nexus 5500 Platform Switch can only be a Layer-2 leaf. This command-line interface will force Cisco Nexus 5500 Platform Switches to always use a specified profile regardless of the profile associated with the network entry in the LDAP database.

When a particular switch needs to use a different include profile for tenant, than what is specified in the tenant profile, use the fabric database override-vrf-profile command in global configuration mode. To disable the overridden profile name, use the no form of this command.

Command Default

The profile returned from the Lightweight Directory Access Protocol (LDAP) is honored as part of the auto-configuration trigger.

Command Modes

Global configuration (config)

Usage Guidelines

When you configure a different include profile name for a tenant, it works by substituting the profile specified in the LDAP database locally at the switch in which this command is configured.

To configure a fabric database profile map, use the fabric database profile-map command in global configuration mode. To disable a fabric database profile map, use the no form of this command.

Command Default

A profile map is not assigned.

Command Modes

Global configuration (config)

To refresh the database, use the fabric database refresh command in privileged EXEC mode.

Command Modes

Privileged EXEC (#)

Usage Guidelines

In the virtual port channel (vPC) setup, the fabric database refresh command is supported only on the vPC primary switch. Also this command requires a matching vni or dot1q hosts. You can use the show fabric database host command to list active vni or dot1q hosts.

To configure the fabric database timers, use the fabric database timer command in global configuration mode. To disable fabric database timers, use the no form of this command.
