Hi
I have 2 HP A10508 switch at core , connected to HP 5120 access layer siwtches using trunk link. I have attached the topology. There are two vlan 10 and 20 and SVI 172.16.10.1/24 and 172.16.20.1/24 respectively.. I have created a VRF(Vpn-instance) DC on Core switches and put interface vlan 20 into that VRF. Users connected to access layer switches in vlan 10 can ping to 172.16.10.1 but users in vlan 20 can not ping 172.16.20.1/24. Even if i create the vlan 20 svi on access layer swith,i can not ping to 172.16.20.1. Here is the configuration of core and access layer switches. Thanks in advance.
