I'm trying to ping L0 on Core1 but it's not working! I tried everything but I don't understand the reason why

VPC6 and 5 are able to ping everything in this network except L0 on Core1

Hi

Your access switch is doing layer 3, right? Are you using Dynamic protocol? Which one?

show ip route on the Access switch does it show the L0 ip address?

Hello,

if possible, post the full running configs (sh run) of all three switches, as well as of the router...

SinghRaminder · ‎06-16-2022

any redistribution happening with Dynamic protocols if you are running them? Any Route-map preventing it?

Thanks
Raminder

Hello

Not enough information however It sounds like the loopback address(s) are not being advertised so the vpcs hosts are able to reach them.
