i need help with layer 3 inter vlan routing and pinging my layer 2 switch.

i having trouble with pinging on my layer 2 switch.

i created vlan 99 on a my layer 2 switch and i want to use it as my management svi.

so on vlan 99 i assigned a IP address of 10.0.0.4 255.255.255.248

and for the default gateway i used 10.0.0.1

i made trunk ports on both my layer 2 and layer 3 switch on my layer 2 int g0/1 and on my layer 3 i did int g1/0/23 as trunks ports and allowed vlan 1-99 through.

and on my layer 3 switch on interface g1/0/24 i connected it to a router and i used the no switch-port command

and gave it ip address of 10.0.0.2 255.255.255.248 on my int g1/0/24.

my router int g0/1 has a ip address of 10.0.0.1 255.255.255.248.

but for some reason i cant ping my layer 2 switch vlan 99

why ?
