    Operation Manual – IPv6 Routing H3C S5500-SI Series Ethernet Switches Chapter 2 IPv6-RIPng Configuration considered as unreachable. After another 240 seconds, if no routing update is received, the router will remove these routes from the routing table. RIPng supports Split Horizon and Poison Reverse to prevent routing loops, and route redistribution.

  • Page 11: Protocols And Standards

    Operation Manual – IPv6 Routing H3C S5500-SI Series Ethernet Switches Chapter 2 IPv6-RIPng Configuration After receiving a response, a router checks the validation of the response before adding the route to its routing table, such as whether the source IPv6 address is the link-local address, whether the port number is correct.
