Cisco ASR 9000 Series Configuration Guidelines

Mobility Support
In global VRF, mobility is not supported. However, you can move a host from one ES to another ES within
the same bridge domain. The host gets a new MAC address and IP address. The host can have multiple IP
addresses for the same MAC address.
In non-default VRF, mobility is supported with the following conditions:
• Basic MAC move: The IP address and MAC address remains the same. You can move a host from one
ES to another ES with the same IP address and MAC address.
• Same MAC address but with a different IP address: The host gets a new IP address
• Same IP address but with a different MAC address: The host gets a new MAC address but retains the
same IP address
• Multiple IP addresses with the same MAC address: Many VMs are involved in the same the MAC move
Restrictions
• In customer VRFs, when host routing is not configured, MAC-IP advertisement is different between zero
ESI and none-zero ESI. When host routing is not configured, MAC-IP with non-zero ESI is advertised
without L3 RT (VRF RT). MAC-IP with zero ESI is not advertised. The following table lists the behavior
of MAC-IP advertisement with respect to ESI and host routing.

• In global VRF, Layer 2 stretch is not supported.
• MAC move in global VRF is only supported if the host is within the same bridge domain. You can move
a host from one ES to another ES within the same bridge domain.
• Duplication of IP address detection is not supported.
• Maximum number of leafs allowed per ESI is two.
Configure EVPN IPv6 Hosts with Mobility
Perform the following tasks to configure EVPN IPv6 Hosts with Mobility feature:
• Configure VRF
• Configure ISIS
• Configure BGP
• Configure AC interface
• Configure BVI interface
• Configure EVPN
• Configure L2VPN
