routing over access link?

Hi,

is this setup valid?

right inervlan routing works fine. I have no issues with this. routing between l3 switch and router works fine as well however i dont understand how this works

router has an ip of 172.22.10.20 that is connected to l3 switch which is on access vlan 99. the interfacce svi for vlan 99 is 172.22.10.20.

my questions is the port thatgoes from rouer (172.22.10.20) to core switch (172.22.10.10) is an access port on vla 99 (with svi 172.22.10.20). how will this work? there is no routing on the core switch. just static route 0.0.0.0 0.0.0.0 172.22.10.10.   wont the access port only carry vlan 99 traffic ? so if any ip on vlan 10 or 20 0r 30 or 40 wants to communicate to outside world, how will it do ?

Re: routing over access link?

Can you check your post as it has the router and the SVI on the same IP address? I can't really read the diagram on iPhone resolution but I see it is different IPs here.
