◆
In general, interfaces facing toward to the network core, or toward
routers supporting the Network Discovery protocol, are configured as
trusted interfaces.
◆
RA messages received from a trusted interface are added to the prefix
table and forwarded toward their destination.
◆
NS messages received from a trusted interface are forwarded toward
their destination. Nothing is added to the dynamic user binding table.
