I am facing some issue below :
LAN : Ping from any host below is giving max latency upto 200ms,
where it is expected to be <1ms
as per our LAN standards
any pc > sw01 > core_sw
sw01 > core_sw
core_sw > sw01
ping latency is equal to 1 ms latency with remote neighbor router
Our Network :<=WAN=>router > core_sw > sw01 > pc
2nos 3845 routers with point to point leased line connectivity
2nos. 3750 stacked L3 core switches
20nos. 3560 L2 switches connected with redundandant links to both core switches.
Network infrastructure layout implemented by the best team as per international standards
STP has selected one of the 20 switches and not core switch
>Request help to reduce network latency
Do making Core switch to be the root bridge for all vlans sort out the issue!
