An IPv6 routing protocol needs to be configured on a PE and a CE to enable them to learn IPv6 routes from each other.
Context
The routing protocol running between a PE and a CE can be EBGP, IBGP, IPv6 static route, IS-IS, RIPng, or OSPFv3. For details, see the configuration of each routing protocol in the HUAWEI NetEngine 8000 F SeriesRouter Configuration Guide - IP Routing.
