如何强制coap服务器节点连接特定的边界路由器？

Question

force nodes to connect to specific border router in a mesh network

Here is my setup; 6 nodes, n1, n2, n3, n4, n5, n6 all running https://github.com/contiki-os/contiki/blob/master/examples/er-rest-example/er-example-server.c Coap server 2 border router, b1, b2 running https://github.com/contiki-os/contiki/tree/master/examples/ipv6/rpl-border-router connected to two Linux board (like Raspberry Pi) L1, L2.

How can I make sure that n1, n2, n3 node only connect to border router b1 and not b2, similarily, n4, n5, n6 nodes only connect to border router b2 and not b1? Thanks!

Need to change panid;

use for boarder-router b1, n1, n2, n3 panid 0xabcd

use for boarder-router b2, n4, n5, n6 panid 0xabce
