Version Description

8.3.16.1 Introduced on the MXL 10/40GbE Switch IO Module.
Usage Information You can congure an arbitrary value in the IP address format for each router. However, each router ID must be
unique. If you use this command on an OSPF router process, which is already active (that is, has neighbors), a

eective at the next reload.

Changing router-id will bring down existing OSPF adjacency [y/n]:
