Explains how a bridge domain profile groups SVIs that use different access VLAN encapsulations into a single Layer 2 broadcast domain.

A bridge domain profile associates multiple regular SVIs with different access VLAN encapsulations so that the SVIs operate in the same Layer 2 broadcast domain.

SVI grouping example

The figure shows three regular SVIs deployed on three vPC pairs and grouped in one bridge domain profile.

Three regular SVIs grouped in one bridge domain profile across three vPC pairs

The example uses these vPC pairs:

  • node101 and node102

  • node103 and node104

  • node105 and node106

The SVI and access encapsulation assignments are as follows:

  • svi-100 uses access encapsulation vlan100 on node101 and node102.

  • svi-101 uses access encapsulation vlan101 on node103 and node104.

  • svi-102 uses access encapsulation vlan102 on node105 and node106.

A bridge domain profile, represented by the l3extBdProfile managed object, groups the three SVIs. The profile has a unique name. The l3extBdProfileCont and l3extRsBdProfile managed objects associate each SVI with the profile.
