FIGURE 122 RHP flow on rings with shared interfaces showing ring 2 RHP flow
Referring to Figure 122 interface 3/1, is the primary interface of the ring 2 master node. It sends
an RHP packet on the ring. Since all interfaces on S4 are regular interfaces, the RHP packet is
forwarded on those interfaces.
When the RHP reaches S2:
• A copy of the RHP is sent out of regular interface e 2/1 onto ring 1. This is in accordance with
the rule that a lower priority RHP can traverse a higher priority ring interface. This RHP is
forwarded until it reaches the ring 1 master where it is discarded.
• A copy of the RHP is forwarded out of the ring 2 tunnel interface on e 2/2
The RHP is received by S1 on e 1/1 and then:
• A copy of the RHP is sent out of regular interface e 1/2 on ring 2
• A copy of the RHP is sent out of regulate interface e 1/3 on ring 1. This is in accordance with
the rule that a lower priority RHP can traverse a higher priority ring interface. This RHP is
forwarded until it reaches the ring 1 master where it is discarded.
