Parameters

tree-root nickname: Displays the TRILL RPF check table information for the TRILL distribution tree rooted at the specified RB. The nickname argument is a hexadecimal number in the range of 0x0 to 0xFFFF.

Usage guidelines

The TRILL RPF check table is used to check whether the incoming port of a broadcast, multicast, or unknown unicast frame is valid. According to the nicknames of the egress RB (root bridge of the TRILL distribution tree to which the frame belongs) and ingress RB in the frame, the RPF check feature checks whether the actual incoming port of a frame is the same as the incoming port specified in the RPF entry. If they are different, the frame is considered invalid and is dropped.

Examples

# Display the TRILL RPF check table information for the TRILL distribution tree rooted at the RB whose nickname is 0x899B.
