Networking requirements As shown in Figure 1, CE2 and CE3 are connected to PE2 and PE3 at the same time. The traffic from CE1 to CE2 is required to be transmitted by load sharing, while the traffic from CE1 to CE3 is transmitted by non load sharing. In order to realize the above requirements, the redundancy mode can be set based on ESI granul ...

Networking requirements As shown in Figure 1, routers PE1, P and PE2 belong to the same autonomous system, and they are required to achieve the purpose of IPv6 network interconnection through IS-IS protocol. PE1, P and PE2 belong to IS-IS process 1 and are all Level-1 devices. IBGP neighbors are deployed between PE1 and PE2, and EBGP neighbors ...
