Host vs. Router

© Copyright Lenovo 2018
Each IPv6 interface can be configured as a router node or a host node, as follows:
 A router node's IP address is configured manually. Router nodes can send
Router Advertisements.
 A host node's IP address is auto‐configured. Host nodes listen for Router
Advertisements that convey information about devices on the network.
Note: When IP forwarding is turned on all IPv6 interfaces configured on the
switch can forward packets.
You can configure each IPv6 interface as either a host node or a router node. You
can manually assign an IPv6 address to an interface in host mode, or the interface
can be assigned an IPv6 address by an upstream router, using information from
router advertisements to perform stateless auto‐configuration.
To set an interface to host mode, use the following command:
NE2552E(config)# interface ip <interface number>
NE2552E(config-ip-if)# ip6host
NE2552E(config-ip-if)# exit
By default, host mode is enabled on the management interface, and disabled on
data interfaces.
The NE2552E supports up to 1156 IPv6 routes.
