Parameters

tree-root nickname: Specifies a TRILL distribution tree by its root RB's nickname, a hexadecimal number in the range of 1 to fffe.

Usage guidelines

The RB uses the TRILL RPF check table to check whether the incoming port of a multidestination frame is valid. The egress RB for a multidestination frame is the root bridge of the frame's distribution tree. The RB checks the RPF check table for the frame's expected incoming port based on the frame's egress and ingress RB nicknames. If the frame is not received on the expected incoming port, the RB considers the frame invalid and drops it.

Examples

# Display TRILL RPF check table entries for the TRILL distribution tree that is rooted at the RB 0x899b.
