  • HSRP between 2 access switches and 2 core switches

    Hi I am looking for running HSRP between 2 access switches and 2 core switches for client PC and Server network’s next-hop redundancy as per attached setup.

    As you can see I have used one /29 network for connecting CORE & ACCESS switches & configure Interface VLAN10 (Layer 3 SVI) with shown IPs and standby IP (VIP).G0/1 on Access Switches & G2/1 on Core Switches are access ports for VLAN10.

    There is a L2 Trunk interconnecting Core-Main/Backup & as well as Access-Main/Backup Switches allowing VLAN10 to allow VLAN10’s HSRP packets to pass through (apart from other HSRP instances).

    Below are the HRSP & Trunk configuration on Core and Access Switches please have a look and suggest if they are correct in term of HSRP implementation, as I can see on both side HSRP master & standby status are fine as desired, but I can’t ping VIP of ACCESS Switch from CORE switch, but the VIP of CORE switch I can ping from ACCESS switch.
