Hello,
Our goal is source all locally generated traffic from the Routing Engine (RE) of a device to use the IP address of the loopback interface. This will concern different traffic such as traffic going from the local RE of the device to the syslog server, NTP server, SNMP server, Radius server etc. To accomplish this we plan to use the "default-address-selection" command.
My only concern was for point to point links where the physical interface address is used for OSPF peering. For this particular connection instead of using the loopback address, we would want the interface address to be used, as we wouldn't be able to form OSPF peering if loopback address was used in this scenario.
There is also another way to source RE generated traffic for various specific protocols by using the source-address command, but this is not that efficient, as it requires us to specify the source address for each protocol.
Could somebody please advise on this setup?
