856 Configuring Routing Interfaces
ip mtu
size
Set the IP Maximum Transmission Unit (MTU) on a
routing interface. The IP MTU is the size of the largest
IP packet that can be transmitted on the interface
without fragmentation. The range is 68–9198 bytes.
bandwidth

Set the configured bandwidth on this interface to
communicate the speed of the interface to higher level
protocols. OSPF uses the bandwidth value to compute
link cost. The range is 1–10000000.
ip unreachables Allow the switch to send ICMP Destination
Unreachable messages in response to packets received
on the interface.
ip redirects Allow the switch to send ICMP Redirect messages in
response to packets received on the interface.
