Bell uses PPPoE+VLAN ID to established the connection. I understant that the usual maxium mtu on a PPPoE connection is 1492 (1500 minus the 8 bits that PPPoE is adding). but that said, Bell allows us to use 1500 (1500+8). Some users did this with their own pfsense "router" and this helps to get a little bit more throuput.

At last problem is solved, it is MTU size issue as RON, RBEVAART, WIMCLEND identified. By the way, just thing that make me confused. - On my draytek router (default MTU: 1438), and this router is configured to be PPPOE client -> every one behind this runs OK - But when I configured my SRX 240 to be PPPOE client with MTU: 1438 -> MTU issue And RFC 4638 allows for larger MTU sizes to be negotiated on PPPoE. Ubuntu 14.04 just doesn't appear to support RFC 4638 out of the box. – kasperd Sep 18 '16 at 17:10 only gigabit does such massive MTU , most of the internet runs with an MTU of 576 so you really wont get more speed doing this , you will probably just give someone elses router Bell uses PPPoE+VLAN ID to established the connection.

PPPOE interfaces generally have an MTU of 1492 bytes, whereas the straight Ethernet interface that they sit on have an MTU of 1500 bytes. When the stack initiates a TCP connection, it advertises the largest MTU of all its interfaces, as per RFC 1193, via the TCP mss option. This is done because, although the outgoing packets are going out on MTU. The Maximum Transmission Unit (MTU) is the maximum frame size that can be sent between two hosts without fragmentation. The MX uses an MTU size of 1500 bytes on the WAN interface. When a packet is sent from a local host to a host in a remote network, the frame may traverse multiple router hops.

PPPoE MTU is a buzz word that many people ask about even if they don’t have anything to do with network engineering. Just being a broadband subscriber with a PPPoE circuit is enough to get introduced to the concept. The Point-to-Point Protocol over Ethernet (PPPoE) is a network protocol for encapsulating PPP frames inside Ethernet frames. It appeared in 1999, in the context of the boom of DSL as the solution for tunneling packets over the DSL connection to the ISP's IP network, and from there to the rest of the Internet.

Mar 29, 2017 · If you experience any problems or any performance-related issues after you modify the MTU size settings, remove the registry keys that you added. back to the top Change the MTU Settings for PPP Connections To have us the MTU Settings for PPP Connections for you, go to the "Here's an easy fix" section.

MPLS over PPPoE Overview. This example shows how to set up MPLS network over PPPoE interfaces. Example network. As you ca see from illustration above, router R2 is pppoe server and routers R3 and R4 are pppoe clients. Our goal is to run MPLS on this network. When running MPLS over PPPoE or other tunnels you have to deal with MTU issues. interface Ethernet0.101 encapsulation dot1Q 101 ip mtu 1492 pppoe-client dial-pool-number 1 end. But now in the #debug ppp negotiation I see that for some reason my MRU being sent is STILL 1500, it's so annoying The Maximum Transmission Unit (MTU) feature of your Linksys router is an advanced configuration that allows you to determine the largest data size permitted on your connection. Generally, if your MTU is too large for the connection, your computer will experience packet loss or dropping internet connection. In some cases, verifying the configuration of the following parameters may improve the performance of the PPPoE connection: MTU Size (1492 bytes max) – A mismatch of MTU size between PPPoE server and client can result is smaller than optimal packets, causing throughput issues and unnecessary fragmentation of packets. Apr 17, 2018 · However, it took us a while to get it set up and we did need to get a little help from CenturyLink to get the PPPoE password. Afterward we simply added the VLAN ID and changed the priority, as well as setting the IPv6 configuration and changing the MTU size to match CenturyLink specs. So far performance has been good based on speed tests.
