Creating a Bridge Group
To configure fallback bridging for a set of switched virtual interfaces (SVIs), these interfaces must be
assigned to bridge groups. All interfaces in the same group belong to the same bridge domain. Each SVI
can be assigned to only one bridge group.
Follow the steps below to create a bridge group and assign an interface to it.
