1. Currently, if I restart Mac OS X then everything is back to normal. What I'd like to do is reset the routing tables to the 'default' (e.g. What it is set to at boot) without a whole system reboot. I think that step 1 is route flush (to remove all routes). And step 2 needs to reload all of the default routes.
2. To flush the DNS cache in these older versions, enter these in Terminal: In macOS El Capitan or newer, run sudo killall -HUP mDNSResponder For macOS Yosemite, enter sudo discoveryutil udnsflushcaches In Mac OS Lion, Mountain Lion and Mavericks, the command is sudo killall -HUP mDNSResponder In Mac.

Nov 18, 2019 Things can also go awry when you upgrade your Mac with new hardware, add memory, install a new graphics card, or change startup volumes. All of these activities can write new data to the parameter RAM. Writing data to the parameter RAM isn't an issue in itself, but it can be a source of problems when you change multiple items on your Mac.

Description

Enable media access control (MAC) flush processingfor the virtual private LAN service (VPLS) routing instance or forthe mesh group under a VPLS routing instance. MAC flush processingremoves MAC addresses from the MAC address database that have beenlearned dynamically. With the dynamically learned MAC addresses removed,MAC address convergence requires less time to complete.

For certain cases where MAC flush processing is not initiatedby default, you can also specify explicit-mac-flush-message-options that additionally configure the router to send explicit MACflush messages. To configure the router to send explicit MAC flushmessages under specific conditions, include explicit-mac-flush-message-options with the statement.

In the VPLS documentation, the word router in terms such as PE router is used to referto any device that provides routing functions.

In certain cases, BGP updates sent by the provideredge (PE) device are delayed for 1 to 5 seconds.

This happens when all of the following condtions aretrue:

• BGP-based VPLS multihoming sites are configured.

• The mac-flush statement is included in theconfiguration.

• a non-minimum designated-forwarder site (site-x, for example)transitions to non-designated-forwarder status

The BGP update being delayed corresponds to the explicit-MACflush notification message sent by site-x's PE device (PE2, for example).This BGP update message is not deferred if the designated-forwarderstatus is lost due to a locally-triggered event (for example, a localattachment-circuit interface going down). In other words, BGP updatemessages are deferred (in Device PE2) only when the designated-forwarderstate is lost due to external events taking place in remote PE devicesthat also hold site-x (for example, in PE1). Suppose, for example,that Device PE1 is the default designated-forwarder with site-x'slocal interface in the DOWN state. Device PE2 defers BGP update messageafter Device PE1's local interface comes back to the UP state.

Options

Mac Os High Sierra

explicit-mac-flush-message-options—(Optional) You can specify one or more of the followingexplicit MAC flush message options:

• any-interface—(Optional) Send a MAC flushmessage when any customer-facing attachment circuit interface goesdown.

• any-spoke—(Optional) Send a MAC FLUSH-FROM-MEflush message to all provider edge (PE) routers in the core when oneof the spoke pseudowires between the multitenant unit switch and theother network-facing provider edge (NPE) router goes down, causingthe multitenant unit switch to switch to this NPE router.

  How to flush the DNS cache in macOS Sierra

  Refreshing the DNS cache on macOS Sierra is a little difference in syntax from refreshing the cache on High Sierra.
  1. Open the Finder and go to Applications > Utilities > Terminal.
  2. Enter (or copy-and-paste if it’s easier) the following syntax at the command line:
  sudo killall -HUP mDNSResponder;say DNS cache has been flushed
  3. Press Return, enter your password, and press Return again.
  4. Listen out for the audio alert to signal that the cache has been successfully cleared.
  If for some reason the above syntax doesn’t work, you can use the following syntax in the Terminal instead:
  sudo killall -HUP mDNSResponder;sudo killall mDNSResponderHelper;sudo dscacheutil -flushcache;say MacOS DNS cache has been cleared

  How to flush the DNS cache in Mac OS X El Capitan and Yosemite

  Both systems can flush the DNS cache in the following ways.
  1. Open the Finder and go to Applications > Utilities > Terminal.
  2. Enter the following syntax at the command line:
  sudo dscacheutil -flushcache;sudo killall -HUP mDNSResponder;say cache flushed
  3. Press Return, enter your password, and press Return again.
  4. Wait for the audio alert to signal a successful flush.
  5. Exit the Terminal.
  For OS X Yosemite versions 10.10, 10.10.1, 10.10.2, and 10.10.3 the process is slightly different. To fully flush all DNS caches, you’ll need to clear both the Multicast DNS (MDNS) and Unicast DNS (UDNS).

  Part 4. The easiest way to flush DNS on your Mac

  Is it complicated to use the terminal to flush the DNS cache? It's ok! We find a way to get your DNS flushed the easier way which is using a third party program and we strongly suggest using PowerMyMac to help you with your DNS and much more.

  PowerMyMac provides you with a one-stop flush DNS operation! Using PowerMyMac, you no longer have to flush your DNS using the terminal and it’s a pretty simple process without having to type in commands or such.
  

  How do you do it?

  1. Download PoweMyMac software and open it

  2. You can see the Toolkit options and click on it

  3. Click on Maintenance and you can see that there is a “view button” and a “scan button”. Click the “scan button” to scan and delete some features on your Mac. But here we save the time, just click the “View button”.

  4. When you come in, you can see the option to “Flush DNS” at the bottom of the list window on the left. Yes, that's right! It is the goal of our operation! Click on the “Clean” button to flush the DNS! Is it very simple?

  There you will see the many benefits of flushing your DNS such as:

  1. Inability to connect to some websites.
