Mixed-Mode Encapsulation Configuration
You can configure a single VMM domain to use VLAN and VXLAN encapsulation. Mixed-mode encapsulation enables you to have a single domain for all EPGs, regardless of encapsulation mode. That makes it easier to track and manage EPGs.
When you create a VMM domain, you can explicitly choose its encapsulation mode: VLAN or VXLAN.
When you create a new EPG for the VMM domain, each EPG for the domain by default uses the VMM domain's encapsulation mode. However, when you create a new EPG and associate it with a domain, you can configure the EPG to override the domain encapsulation mode and use another mode.
For example, you may choose VLAN configuration when you create a VMM domain. When you create a new EPG for the domain, you may configure it to use VLAN—the domain mode—or you may configure it to use VXLAN.
Note |
Mixed-mode encapsulation is available for Cisco ACI Virtual Edge in local switching mode only. |
Encapsulation Pool Combinations
Your ability to add and delete VLAN and multicast pools for a VMM domain depends on whether EPGs are associated with the domain.
If no EPGs are associated with the VMM domain, you can add and delete VLAN and multicast pools. You can do this regardless of whether the VMM domain default encapsulation mode is VLAN or VXLAN.
If EPGs are associated with the VMM domain, you cannot delete existing VLAN or multicast pools.:
-
VLAN—You can configure both VLAN and multicast pools.
VLAN is the default encapsulation mode for the domain. New EPGs created for this VMM domain use VLAN encapsulation by default. You can configure EPGs to use VXLAN encapsulation if multicast pools are configured in the VMM domain.
Note
Configure the private VLAN as internal in the VLAN pool for internal switching.
-
VXLAN—You can configure both VLAN and multicast pools. VXLAN is the default encapsulation mode for the domain. New EPGs created for the VMM domain use VXLAN encapsulation by default. You can configure EPGs to use VLAN encapsulation if VLAN pools are configured in the VMM domain.
