Hybrid SEP+RRPP Ring Networking

Hybrid SEP+RRPP Ring Networking

In hybrid SEP+RRPP ring networking, SEP networks need to report topology changes to RRPP networks on the edge devices of SEP networks.

Figure 17-14 shows a networking diagram of hybrid rings running SEP+RRPP.

Figure 17-14  Hybrid rings running SEP and RRPP

In Figure 17-14, PE1, PE2 and LSW1 to LSW3 form a SEP segment to access the RRPP ring. PE1, PE2 and LSW1 to LSW3 are at the access layer and transparently transmit Layer 2 unicast and multicast services. When SEP runs at the access layer, redundancy protection switching can be implemented at the access layer.

If the topology of the access layer changes, a node in the SEP segment sends a Flush-FDB packet to instruct other nodes to update their MAC address tables and ARP tables. PE1 and PE2 at the edge of the SEP segment send a TC packet to notify the aggregation layer of the topology change in the SEP segment.
