In this section, a configuration example of a three nodes ring is given. The ring has the following topology:
+-------------------------+ +-------------------------+ | | | | |->|ge-1/2/4 ge-1/0/1|<------->|ge-1/2/1 ge-1/0/2|<--| | | node 1 | | node 2 | | | | | | | | | +-------------------------+ +-------------------------+ | | | | | | +-------------------------+ | | | | | |->|ge-1/0/4 ge-1/0/3|>--------------------------------------| | node 3 | | | +-------------------------+
The configuration in this section is only for the RAPS channel. The bridge domain for user traffic is the same as the normal bridge domain. The only exception is if a bridge domain includes a ring port; then it must also include the other ring port of the same ring.
