Configuring Router Discovery
The Router Discovery protocol is used by hosts to identify operational routers on the subnet.
Router Discovery messages are of two types: “Router Advertisements” and “Router
Solicitations.” The protocol mandates that every router periodically advertise the IP
Addresses it is associated with. Hosts listen for these advertisements and discover the IP
Addresses of neighboring routers.
Router Discovery Configuration
Use the Router Discovery Configuration page to enter or change Router Discovery
parameters.
To display the page:
Subnet Mask Enter a Subnet Mask for the VLAN Routing Interface.
IP MTU Specify the maximum size of IP packets sent on an interface. A valid
range is from 68 bytes to the link MTU. The default value is 1500. A
value of 0 indicates that the IP MTU is unconfigured. When the IP MTU
is unconfigured, the router uses the link MTU as the IP MTU. The link
MTU is the maximum frame size minus the length of the layer 2 header.
