You can configure the interface so that the receiving and sending of OSPF packets are prohibited, and thus the networking adaptability of OSPF is enhanced and system resource consumption is reduced.
This describes how to configure the interface to fill in the Interface MTU field of the DD packets with the actual MTU value when the interface sends DD packets. By default, the MTU field of DD packets adopts 0.
Because RFC2328 and RFC1583 adopt different route selection rules, you can configure the external route selection rules that are compatible with RFC1583.
OSPF neighbor relationship flapping suppression works by delaying OSPF neighbor relationship reestablishment or setting the link cost to the maximum value.
