ASPATH Prepend is used to prefer inbound path. To make path less preferable , we can prepend its own AS number as BGP router prefers the shortest as-path

    hello sir i would like to ask question related to this topic my router and desktop is connected through lan cable and in my router 802.1p qos value is set 7 by me and in windows GPEDIT POLICY my DSCP value is set 46 for online gaming application so is this good marking done by me ?. my main goal to achieve is low latency in gaming

    • @selvajegannetworkingchanne3222
      @selvajegannetworkingchanne3222 Před 9 dny

      yeah looks good , as EF provides low loss, latency, and jitter

    • @Amit3D2Y
      @Amit3D2Y Před 9 dny

      is 802.1p also good its on high ? and sir there is more folder in side gpedit qos policy called confim packets and non confirm packets is this there is 5 service type is this folder important for low lag and less packet burst ? layers 2 value in gpedit all value set to 7 is this value for gaming ?

    it would be nice to mention what are disadvantages of this setting, for example MAC address flapping observed in logs, as MAC ageing will not take place with this fast change.

    Sir, I’m confused about one point. When applying a route-map, why did you do #route-map MED permit 10 #set Metric 100 and no #match ip address command and no ACL either? Setting the route-map without an ACL, and without a matching command, what would be the result be?

    • @selvajegannetworkingchanne3222
      @selvajegannetworkingchanne3222 Před 2 měsíci

      Route map with metric statement is for influencing inbound traffic and default MED value is 0. Setting metric higher than MED value=0 will give less preference to that traffic----MED for inbound traffic and lowest MED is preferred . if im not setting the metric default MED 0 applies

    Hi Selva, Your videos are so helpful. Thanks. Glad that you are on udemy, 😅 I have a problem in my topology, kindly let me know if you have any ideas to debug. Issue description: Connectivity issue with clients and VRRP Peer after upgrading from older firmware to new firmware. Two core routers are available. Core-1 as master core-2 switch as backup. This is configured as a VRRP peer. Problem is that, clients were not able to reach VRRP peer after upgrading to a specific firmware. In the switch, cr-1 and cr-2, mac and arp learning is happening successfully and after clearing arp, it-was able to re learn the mac addresses properly. Facing duplicate address issues on many vlan addresses. Didn’t see same addresses configured on master and backup router. Workaround to restore the clients connectivity to vrrp peer is : 1. Flapping the respective ve ,interface clients connects to. 2. Downgrade back to working version. Any idea how to debug this issue ? Please let me know, if you are on discord.
